The device driver does not see one of the SCSI devices.
•
Make sure the SCSI devices have different ID numbers.
•
Make sure both, but only, the ends of the SCSI bus are terminated.
•
Check the cable and power connections.
•
Check the ordering of BASEDEV= entries in the CONFIG.SYS file to be
sure that the boot device is loaded first.
•
Verify that the adapter is not turned off in the SCSI BIOS
Configuration Utility and that the adapter is not excluded using the
/EXCLUDE command line option.
•
Reboot the computer.
OS/2 attempts to install to or boot from an IDE drive instead of the
SCSI drive.
The system BIOS finds the IDE drive before it finds the SCSI drive, and
therefore uses the IDE drive as the boot device.
•
Check that the appropriate BASEDEV= line ( BASEDEV=SYM8XX.ADD /V
or BASEDEV=SYM_HI.ADD /V ) appears first in the CONFIG.SYS file.
•
Disable the IDE drive in the CMOS setup.
•
On some hardware platforms, the IDE drive must be physically
disconnected before installing to a SCSI drive.
System is booting from a hard drive and the following message
appears at bootup:
OS/2 is unable to operate your hard disk or diskette drive.
The system is stopped. Correct the preceding error and
restart the system.
This problem occurs when the system is booting from a hard drive
attached to an IDE bus, a SCSI disk is attached to the LSI Logic host
adapter, and the SDMS
BASEDEV= line ( BASEDEV= SYM8XX.ADD /V or
BASEDEV= SYM_HI.ADD /V ) appears in the CONFIG.SYS file before the
IDE device driver statement.
