Getting Started  
Host Adapter and the SCSI Bus  
I/OHIGHWAY is a bus mastering host adapter which works with the host computer to  
provide control for the SCSI bus. By daisy chaining peripheral devices together, up to  
seven devices can be linked with I/OHIGHWAY. The host adapter can be placed in any  
standard PCI slot on the bus.  
2
SCSI bus preparation  
Each peripheral device attached to the SCSI bus can either be an internal or external  
device. Each peripheral has a specific device ID, commonly referred to as a SCSI ID.  
Please refer to your peripheral documentation to determine switch or jumper settings for  
SCSI ID’s. No two devices can have the same ID; the device ID uniquely defines the  
device to the SCSI bus.  
SCSI bus termination  
The SCSI bus structure has a length limitation as well as a requirement for termination at  
each end of the SCSI cable. The cable is designed to connect in a daisy chain fashion.  
No branching is permitted in the SCSI bus. The first and last physical SCSI device on  
the SCSI bus must be terminated (FIGURE 2).  
FIGURE 2 – Examples of SCSI bus termination  
®
initio  
 
6
Getting Started  
I/OHIGHWAY’s SCSI termination can be set to auto-termination or programmable mode  
via the SmartSCSI Setup Utility. This feature allows the operator to switch the auto-  
termination On or Off. If auto-termination is switched off, the operator can manually  
program termination for the host adapter. There are three ways to manually control  
terminating the host adapter on the SCSI bus (see TABLE 1).

Hardware Installation  
Installation Basics  
The internal cable permits connection of multiple internal devices. SCSI devices that are  
connected to the internal connector are installed inside the host computer enclosure.  
The external connector is accesible through the D-shell connector at the back of the  
host system and is designed to connect devices outside the host system enclosure.

TABLE 2 - Connector Details  
To increase the reliability of the cabling being used with the host adapter, it is recom-  
mended that the following guidelines be observed:  
• SCSI-1 – up to 6 meters or 20 feet  
• FastSCSI – up to 6 meters or 20 feet  
• Impedance of the cable should be between 90-110 ohms  
• Use high quality shielded connectors  
Installation inTen Easy Steps  
1 Power down the host computer and all peripherals.  
Remove the cover from the host system. You may need to refer to the system manual  
for cover removal. If necessary, identify the PCI sockets inside the host system with  
the aid of the system documentation.  
2 Use static electricity discharge precautions.  
Remove possible static discharge potential from any objects that the host adapter  
may come in contact with before installation. This can be accomplished by touching  
a bare metal chassis rail after you have turned off the power.

Hardware Installation  
3 Inserting the host adapter  
Orient the host adapter for installation so that the external connector is facing the  
back of the system unit and align the card with the PCI connector on the system unit  
(see FIGURE 3).  
Holding the adapter by the mounting bracket and the card edge, match up the card  
edge connector with the PCI host computer socket and insert the card into the  
socket. Once the connector is in the PCI expansion slot socket tighten the mounting  
bracket screw to secure the card in place.  
FIGURE 3 – Inserting the host adapter into a PCI slot  
4a Installation of internal SCSI cables  
The number of internal and external connectors for Initio’s SCSI host adapters are  
referenced in the hardware installation section (TABLE 2).  
All internal connectors may be used simultaneously or singularly, depending on  
your bus configuration. Installation of internal SCSI cables must be performed  
before replacing the system covers. The internal ribbon cable is made with multiple  
connectors attached and used to daisy chain the host adapter with two or more  
devices. It is important that the cable be installed correctly for proper operation.  
The cable has a colored stripe running the length of the cable, on the edge distin-  
guishing the pin one side of the connector. These identifying markings must match  
when mated on the host adapter board.

Hardware Installation  
When attaching FastSCSI devices, use the 50-pin FastSCSI cable connector on the  
host adapter. Align the internal cable into the host adapter and the other cable  
connectors in a similar fashion into the other SCSI device connectors as described  
in the appropriate manufacturers instructions.  
FIGURE 4 – Connecting the 50-pin internal flat ribbon cable  
4b Installation of external SCSI cables  
Installation of external SCSI cables can be performed after the cover has been  
closed. The cable is limited in length to a total of six meters including any internal  
cabling. The external cable can be daisy chained to include up to seven with the  
host adapter in combination with internal devices. The external cable is designed  
to be inserted only one way, requiring termination at the end peripheral device on  
the bus (FIGURE 5).

Hardware Installation  
5 Drive activity LED  
A drive activity LED is designed into the host adapter to indicate when a data  
transfer is being made. Connection to the LED is optional and cabling is not in-  
cluded with this kit. Each host adapter has one four-pin connector. Please refer to  
the host adapter’s illustration (FIGURE 1) for the LED connector that will accomodate  
the LED cable.  
6 Multiple Initiators  
Under some circumstances multiple initiators can be used on a single SCSI bus. The  
bus is configured to have more than one host adapter inserted into at least two  
distinctly different computer systems sharing peripheral devices. In these circum-  
stances, it is possible to have one of the two computer systems turned off. Under  
these conditions, the host adapter has a jumper that can be enabled (closed) to set  
the active on-board termination on all the time, regardless of whether power is  
applied or not. The host adapter is shipped without the jumper installed and need  
not be changed in most cases.  
7 Close the cover on the host computer  
Visually inspect the configuration you have installed to verify that all cables have  
been inserted correctly. Close the cover on the host computer. The hardware  
installation for the host adapter is now complete.  
8 Host computer configuration  
Most computer manufacturers with a PCI bus automatically configure the add on-  
card or host adapter I/O Port address, IRQ Channel and BIOS address. If this is not  
the case with your computer system, you will need to manually configure your  
system.  
There are two means of configuring the PCI bus from the host computer system:  
1. Setting jumpers on the host system motherboard.  
2. Setting CMOS BIOS incorporated into the host system.  
You will need to refer to the host computer system documentation to complete PCI  
bus activation and setup.  
If the host system will be using a SCSI device to provide system boot capability, then  
the system CMOS drive type settings may need to be changed. Under some condi-  
tions the system will expect the boot disk to be an IDE drive. This must be changed  
in order to boot from a SCSI device.

Hardware Installation  
9 System startup  
The newly installed SCSI bus is now ready to power up. Switch on peripheral and  
host computer system power. The system monitor should display the following  
information, but may vary, based on the system BIOS manufacturer.  
• The normal Power-On Self Test and memory test procedure.  
• The host adapter sign on message including a list of attached SCSI devices.  
The list should match the peripheral devices attached to the bus. In most cases the  
host computer system is now configured and ready for use.  
Some situations will require that a low-level format be performed using the host adapter  
SmartSCSI Setup Utility to initialize a SCSI disk drive and lay the foundation for a bootable  
SCSI drive.  
10 SmartSCSI Setup Utility  
The SmartSCSI Setup Utility simplifies the SCSI installation process by eliminating  
the need for opening the system to change system jumpers and switch settings. All  
necessary host adapter functions are accessible through the utility, simplifying  
customization for your system needs. Initio’s SmartSCSI Setup Utility is divided into  
five segments identified by: Scan Bus; Device Setup; Adapter Setup; BIOS Setup; and Disk  
Utility. These program functions are accessible by typing <CTRL><I> at the boot-  
up prompt.  
Hard Disk Drive Preparation  
A new SCSI disk drive is normally low-level formatted at the factory to simplify installa-  
tion. The drive can be used as it comes from the factory once it is partitioned for  
system operation.  
Low-level Format  
A low-level format will erase any data that is stored on the target disk. Before attempting  
to perform a low-level format be sure the data on the target disk has been backed up. A  
low-level format can be achieved via the SmartSCSI Setup Utility for I/OHIGHWAY.  
The low level format sets the media to a state which is easily recognized by the host  
adapter on the SCSI bus. Once this format is completed, you will need to partition the  
drive. Refer to your operating system documentation for further information on parti-  
tioning drives.

Host Adapter Setup  
Running the SmartSCSI Setup Utility  
To start the SmartSCSI Setup Utility, verify that all devices attached to the SCSI bus are  
powered up when the host computer system is turned on. Once the power switch has  
been turned on and the system begins its on screen power up sequence, the Initio banner  
will be displayed for a brief period. During this time the Initio SmartSCSI Setup Utility is  
accessible by pressing the <Ctrl> key and the <I> key at the same time. When displayed  
on your system monitor, the following message indicates that the host system is ready to  
accept your keyboard input.

!!! Press <Ctrl> <I> for SmartSCSI Setup Utility !!!  
Main Menu Options  
SmartSCSI’s main menu provides five possible setup options for meeting your system  
configuration:  
Scan Bus  
Device Setup  
Adapter Setup  
BIOS Setup  
Disk Utility  
Scan Bus  
This option scans the SCSI bus. All device ID’s are displayed on the screen including  
SCSI ID’s without devices attached. This allows for a better definition of location and  
priority on the SCSI bus.  
• A device ID should only be changed if it conflicts with another device address on the same bus. Refer  
to your peripheral documentation for changing SCSI ID’s.  
• The best ID for a bootable hard disk is SCSI ID-Ø.  
Device Setup  
Asynchronous Transfer. Use this option to set the synchronous data transfer mode.  
I/OHIGHWAY will transfer data at a maximum rate of 10 MBytes per second in synchro-  
nous mode and a maximum rate of 5 Mbytes per second in asynchronous mode. Use  
this option to set the synchronous data transfer mode. The default setting for this  
option is for synchronous operation. (no)  
Maximum Synchronous Transfer Rate. This option determines the speed at which  
data is moved across the SCSI cable. I/OHIGHWAY has the option of running up to 10  
MBytes per second.

Host Adapter Setup  
DOS Space > 1 GB. Using this option allows for single disk capacities to be extended  
up to 8 GBytes (yes). Please refer to the Appendix titled DOS Space > 1 GB for further  
information on this feature.  
• (NO) DOS limits the number of cylinders per drive to 1024. The host adapter defines  
head and sector usage to 64 heads and 32 sectors. This format allows for maximum  
capacity of 1 gigabyte per disk storage.  
• (YES) The upper limit can be extended from 1 GByte to 8 GBytes by increasing the  
number of heads to 255 and sectors used per track to 63. This is a powerful option.  
DATA CAN BE LOST BY CHANGING SETTINGS.  
Spin Up Disk Drive. This option is used to initiate motor spin-up for SCSI disk drives.  
The host adapter BIOS can limit system power requirements during power-up. This is  
accomplished by signaling the device to start at delayed intervals (default setting will be  
‘no’).  
Enable Disconnect. The host adapter uses this option to allow a device to temporarily  
disconnect from the SCSI bus (referred to as disconnect/reconnect). This allows the  
host adapter to perform other functions on the bus while the device is temporarily  
disconnected. The device and the host adapter can then reconnect when the bus is  
needed (default setting will be ‘yes’).  
Adapter Setup  
Host Adapter SCSI Bus ID. Used to change the adapter’s SCSI ID on the SCSI bus.  
The narrow host adapters provides eight ID’s available numbered 0-7, with 7 having the  
highest priority (and ID-7 reserved for the host adapter).  
Installation of additional host adapters is permitted on the same PCI bus. This will allow  
the system to have more than one SCSI bus attached. Under these conditions, SCSI  
ID’s can be repeated.  
Boot Device ID. This option selects which SCSI device will be the designated boot  
device for the system. The default ID for this option is 0.  
SCSI Terminators. This option is used to set auto-termination located on the host  
adapter card. This option is also used to manually control termination on the host  
adapter. The normal setting for this option is auto.  
®

15  
Host Adapter Setup  
SCSI Parity Check ON. Select this option to enable or disable parity checking on the  
SCSI bus by the host adapter. The default setting for this option is on (yes).  
NOTE: If this option is set ON, be certain that the peripheral SCSI device also has this option turned  
ON.  
BIOS Setup  
Enable Host Adapter BIOS. This option controls the host adapter usage of SCSI disk  
I/O routines inside the host adapter BIOS. By disabling this option you will eliminate the  
host adapter’s ability to utilize boot capabilities in I/OHIGHWAY. Setting this to “no” will  
also disable all subsequent features displayed by this on-screen panel. The default  
setting will be on. (Yes)  
BIO SUPPORT for More than Two Drives. This option supports two or more disk  
drives on the SCSI bus for MS-DOS 5.0 or later when enabled. The optimum device  
identification (ID) for multiple drive operation is device ID-0 for a system disk and device  
ID-1 for the second drive. The default setting will be on. (Yes)  
BIOS Treat Removable Disks as Fixed Disk. This option is able to treat removable  
disks as fixed disks. With this option selected you can run removable disk media without  
additional software drivers. The default setting will be off. (No)  
BIOS Support for Bootable CD-ROM. This option allows users to boot from a CD-  
ROM by replying with Yes at the prompt. Only one bootable CD-ROM will be allowed at a  
time. The default setting will be off. (No)  
Disk Utilities  
Format Disk. Use this option to perform a low level disk format on the target device.  
The format will erase all data resident on the targeted disk drive. Refer to the section  
titled “Hard Drive Preparation” for additional information.  
Verify Disk. This option will verify the media of a successfully formatted device and  
verify that the drive is functioning properly. Verify will also identify and flag any bad  
sectors on the disk so that during operation these flagged sectors will not be used. If a  
bad sector is found you are given two options shown below:  
• Reassign will assign the flagged location to another sector on the disk.  
• Skip will not reassign the flagged location.

INICD.SYS is automatically loaded in the CONFIG.SYS start up file by the Initio  
DOSSETUP or SETUP programs. INICD.SYS requires that the Initio ASPI Manager be  
loaded. INICD.SYS can be loaded with either the DEVICE= or DEVICEHIGH= command.  
INICD.SYS can be found on INI-9XXXU/9XXXUW DRIVER DISK 1. Below is a list of  
command line options and examples.  
/D: /d: This option is used to specify the name of the device driver. The name specified  
must also be passed to MSCDEX.EXE on it’s command line (Using the same /D: or /d:  
option). The name specified must be 8 or less characters in length. Valid characters are  
the A-Z, a-z, 0-9 and underscore. The name must start with a letter.  
Examples:  
/D:INICD001  
/d:mscd001  
/d:MYCD01  
/T /t  
This option is used to specify a Time out value to be used when sending  
commands to a CDROM drive. If a CDROM drive does not respond to a command  
within the specified time out then the command will be aborted and an appropriate  
error message will be displayed. The time out value is specified in minutes. Valid values  
®

MS-DOS/Windows 3.1x Driver Installation  
are 1-9 and D or d. The D or d values are used to Disable the time out mechanism. If  
the time out mechanism is disabled then faulty hardware can lock up the system.  
Examples:  
/T4  
/Td  
/TD  
/T1  
/X /x  
This option is used to exclude particular CD-ROM drives. Excluded CDROM  
drives are identified by specifying the host adapter, target id and lun. These values are  
spereated by a colon. Groups of CDROM drives (or wild cards) can also be identified.  
Below are examples of the different ways CDROM drives can be excluded:  
/X0:1:2  
/X0:2  
/X0  
This will exclude the drive on Host Adapter 0, with target ID 1  
and lun 2.  
This will exclude the drive on Host Adapter 0, with target ID 2  
and ANY lun  
This will exclude ALL drives on Host Adapter 0.  
SAMPLE CONFIG.SYS AND AUTOEXEC.BAT FILES  
These samples assume that the user has loaded the Initio drivers in the following  
directory: c:\iniaspi.  
Config.sys:  
DEVICEHIGH=c:\iniaspi\aspi910u  
DEVICEHIGH=c:\iniaspi\inicd.sys /D:INICD001  
Explanation:  
The first line loads the ASPI manager and the second line loads the CDROM driver  
specifying the device name INICD001.  
Autoexec.bat:  
Mscdex /D:INICD001  
Explanation:

ASPI Disk Driver Command Line Options  
INIDISK.SYS is a DOS block device driver for supporting SCSI fixed disks, removable  
disks and MO devices. INIDISK.SYS is automatically loaded in CONFIG.SYS start up file  
by the Initio DOSSETUP or SETUP programs. INIDISK.SYS requires that the Initio ASPI  
Manager be loaded. INIDISK.SYS can be loaded with either the DEVICE= or  
DEVICEHIGH= command. INICD.SYS can be found on the INI-9XXXU/9XXXUW DRIVER  
DISK 1. Below is a list of command line options and examples.  
/R /r  
This option specifies the number of logical drives to reserve for MO and  
removable disk devices. MO and removable disks media are capable of being parti-  
tioned just like a fixed disk. For every DOS partition on the media a logical DOS drive  
letter will be available. INIDISK.SYS will support as many logical drives as required (up to  
the maximum supported by DOS) based on the partitioning of the media that is present  
when your system boots. However, the media may be removed at any time and a new  
disk may be inserted. The new disk may have more (or less) partitions then the original  
disk. The /R /r option is used to reserved drive letters at start up in order to facilitate a  
disk change to a disk with more partitions than the original disk present at boot time.  
The value after the /R /r option determines how many drive letters will be reserved on a  
device basis. For example, if the user specifies a /R4 option and there are two removable  
devices attached to the SCSI bus, then a total of eight (8) drive letters will be reserved.  
/T /t  
This option is used to specify a Time out value to be used when sending  
commands to a SCSI drive. If a SCSI drive does not respond to a command within the  
specified time out then the command will be aborted and an appropriate error message  
will be displayed. The time out value is specified in minutes. Valid values are 1-9 and D  
or d. The D or d values are used to Disable the time out mechanism. If the time out  
mechanism is disabled then faulty hardware can lock up the system.  
Examples:  
/T4  
/Td  
/TD  
/T1  
/X /x  
This option is used to exclude particular SCSI drives. Excluded SCSI drives are  
identified by specifying the host adapter, target id and lun. These values are spereated

directory: c:\iniaspi.  
Config.sys:  
DEVICEHIGH=c:\iniaspi\aspi910u  
DEVICEHIGH=c:\iniaspi\inicd.sys /R2  
Explanation:  
The first line loads the ASPI manager and the second line loads the SCSI disk driver  
specifying that a minimum of two drive letters be reserved for each MO and removable  
disk attached to the SCSI bus.  
ASPI Partition & Format Utility  
INIFDISK.EXE is a DOS ASPI partition and format utility. It requires the ASPI910U.SYS  
and INIDISK.SYS drivers to be loaded in order for it to function properly. INIFDISK.EXE is  
installed by the Initio DOSSETUP or SETUP programs. Upon invocation, the initial  
screen will have two windows. The top window will list all of the SCSI devices installed in  
the system. The user can highlight a particular device by using the up and down arrow  
keys. The bottom window will display information about the device that is currently  
highlighted in the top window. Inifdisk.exe can partition and format any SCSI storage  
device that is not being controlled by the BIOS, this includes SCSI disks, magnetic  
optical drives, and removable media devices. INIFDISK will display two screens in which  
the bottom portion will explain all commands possible in the top window.

The SCO UnixWare drivers developed by Initio will be installed on the disk drive used for  
system initialization. It is strongly suggested that the selected procedure be read and  
understood before continuing with the system configuration or change. Please read the  
instructions carefully.  
Updating interrupts and hardware settings  
The following interrupt configuration settings are suggested as the most effective means  
of providing a controller interrupt to the host adapter:  
• Host adapter interrupt level must be set to IRQ 10 for proper installation of the  
Initio driver.  
Please refer to your system documentation to set the interrupt levels and your periph-  
eral documentation for help in setting SCSI IDs.  
Installing the Initio driver in a new UnixWare system  
Drivers for the host adapter may be found on the INI-9XXXU/9XXXUW DRIVER DISK 2.  
In most cases you will load the drivers during a new installation of UnixWare from CD-  
ROM. The driver is loaded during the early stages of the installation procedure. The  
UnixWare installation program will prompt you for the required parameters as the  
installation procedure progresses. It is highly recommended that you have a copy of the  
SCO UnixWare Installation Handbook and SCO UnixWare System Owner Handbook for

• pkgadd -d diskette1 , press <ENTER>  
2 Select i910u ihv hba from the list of available host drivers, press <ENTER>.  
3 If the INI-9XXX is intended to be the bootable host adapter, the next step to updating  
the driver will require a revision to the I910u file. These instructions will guide you  
through changing the current software settings for UnixWare to establish the INI-9XXX  
as the host adapter for your boot device:  
• At the system command prompt, type  
• cd /etc/conf/sdevice.d  
• Use “vi” or another editor to modify the file I910u by adding a line  
• locate the line $version2  
• edit the file by adding the line $static immediately following $version2.

as a non-bootable host adapter for your device:  
• At the system command prompt, type  
• /etc/conf/bin/idbuild -M i910u <ENTER>  
• cd / <ENTER>  
• shutdown -g0 ( 0 is Zero ) <ENTER>  
• Y <ENTER>  
5 Exit the UnixWare program and reboot your system to initialize the new device driver  
to control INI-9XXX.  
Using Multiple Host Adapters  
UnixWare is capable of supporting up to eight SCSI busses. If you choose to use multiple  
host adapters in your system, verify that each host adapter shared interrupt level is set to  
IRQ10. Please refer to your system documentation to set the interrupt levels.  
Space for each host adapter in the system is configured and allocated by a separate line in  
the file /ETC/CONF/SDEVICE.D/I910U.  
1 Verify that Y is selected in the second field at the line starting at I910u in the file /ETC/  
CONF/SDEVICE.D/I910U for each INI-9XXX in the system.  
UnixWare will automatically rebuild the kernel when an additional INI-9XXX is detected.  
Removing the Initio driver from a UnixWare system  
1 Once a UnixWare session is established and a command prompt is ready, type (recall that UnixWare  
is case sensitive):  
• Type: /etc/conf/bin/idinstall -d i910u <ENTER> to delete the following files:

Troubleshooting  
In the following section you will find commonly asked questions and answers to problems  
encountered during the installation of your host adapter.  
Question: Why isn’t the INI-9XXX banner “!!! Press <CRTL><I> for SmartSCSI Setup Utility  
!!!” displayed when I power up the host system?  
Answer:  
Verify that all cabling to the host adapter is installed correctly, refer to the hardware  
installation section of this manual.  
Question: On boot-up the message “SCSI BIOS Installed” is displayed, but my system hangs.  
Answer:  
Verify that the CMOS interrupt structure is set to INTA and the CMOS IRQ level  
matches the jumper settings on the motherboard. Refer to your PC user manual.  
Question: On boot-up, not all the peripherals are scanned and recognized.  
Answer:  
Verify that each of the SCSI devices on the bus has its own distinct SCSI ID number  
and all peripherals are receiving power. Refer to your peripheral manual for informa-  
tion regarding changing SCSI ID’s.  
Verify the SCSI Termination is set correctly. Make sure the last peripheral on the  
SCSI bus has termination. See the peripheral manual for proper termination  
information.  
After the above steps are executed, if you are still not recognizing all attached  
peripherals, configure the host adapter to operate in an Asynchronous Transfer  
mode by changing its setting under the SCSI Devices Setup section of the  
SmartSCSI Setup Utility. This feature is discussed thoroughly in the chapter entitled  
Host Adapter Setup.  
Question: On boot-up I get a message “Missing Operating System”, displayed. The boot drive  
is greater than 1 gigabyte.  
Answer:  
Verify the “DOS SPACE> 1 GB” is enabled in the INI-9XXX SmartSCSI Setup Utility.  
Question: Under SCO UnixWare, the system displays a panic message or crashes during  
bootup:  
Answer:  
Reboot the system and verify that the INI-9100A is using IRQ10. Please Refer to  
your system documentation to set the interrupt levels and your peripheral docu-  
mentation for help in setting SCSI ID’s.  
In order to boot from the old UnixWare kernel, reboot the system and execute the  
following steps:  
• Begin an interactive boot session by pressing the <SPACEBAR> at the  
BOOTING UNIXWARE prompt.  
• At the system [boot]# prompt, type KERNEL=unix.org <ENTER>  
• Type go <ENTER>.

Troubleshooting  
Consult the SCO UnixWare Installation Handbook “Troubleshooting” section to help  
isolate the problem. If it becomes necessary to remove the Initio device driver,  
please consult the “Removing the Initio Driver from a SCO UnixWare System”  
section of this document.  
B: DOS Space > 1GB  
The default disk head mapping for Initio SCSI host adapter is 255 heads and 63 sectors.  
This translates to a maximum accessible capacity of 8 GBytes per drive under MS-DOS.  
Warning: If you have already installed the operating system on your hard drives,  
changing the head mapping will corrupt your files and cause other unexpected prob-  
lems. Before changing any “DOS Space > 1GB” option setting, please back up your disk  
drives. Then you should run the FDISK utility to delete all the partitions on your selected  
disk drive. At this point you can switch the setting, reinstall the operating system, and  
restore your backed up files.  
All device drivers for the INI-9100A Host Adapter will support different head mappings  
based on the setting of “DOS Space > 1GB” option.  
MS-DOS, OS/2 & Windows NT  
Under MS-DOS, OS/2 & Windows NT, we recommend you enable “DOS Space > 1GB”  
option if your SCSI hard disk has more than 1 GByte capacity.  
SCO UNIX  
SCO UNIX does not have a 1 GByte barrier. Therefore, the “DOS Space > 1GB” option is  
not required to be enabled; however, you must make sure the root file system is located  
below 1024 cylinders in order to perform the kernel boot routines. If the size of the root  
file system is greater than 1 GByte or the location of root file system is beyond 1 GByte,  
you should enable the “DOS Space > 1GB” option.  
SCO UNIX can not support different head mappings for each disk drive under the same  
host adapter. The head mapping will be based on the setting represented by target ID 0.  
®
initio  
 
53  
Troubleshooting  
Drives with Multiple Operating Systems  
It is mandatory that the same head mapping be used across multiple operating systems  
on one drive. However you can use different head mappings on different drives with the  
exception of SCO UNIX. It is recommended that you enable “DOS Space > 1GB” option  
if the capacity of your SCSI hard disk has more than 1 GByte.
