Problems and Solutions

The screen is difficult to read when I run the ECU.
Try pressing F5 to toggle the display between color and mono-
chrome modes. This may enable you to read the screen more easily.
I installed the host adapter, and my computer will not boot from the SCSI disk drive.
If both SCSI and non-SCSI disk drives are installed, then the non-
SCSI disk drive is always the boot device. If your system has only
SCSI disk drives, check the following:
1
Make sure your computer system's CMOS setup is set to No
Drives Installed, as is required for SCSI host adapters.
2
Try setting the SCSI boot drive to SCSI ID 0. This is normally
done by changing jumpers or switches on the drive. On each
SCSI bus, SCSI devices must be set to a unique SCSI ID. See
SCSI ID Setting on page 2-15.
3
Try disabling Wide Negotiation for any 8-bit SCSI devices con-
nected to the host adapter. See Initiate Wide Negotiation on page
3-16.
4
Try enabling Include in BIOS Scan in the BIOS and SCSI
Device Configuration option. See BIOS and Device Configura-
tion on page 3-11.
5
Make sure the SCSI bus is properly terminated. See Termination
on the SCSI Bus on page 2-9.
6
You may need to low-level format the SCSI hard drive. If so,
first back up all data on the disk, then run the format utility
accessible through the ECU. See Utilities on page 3-18.
Similar formatting utilities for removable media devices are included
in the Adaptec EZ-SCSI software package for the DOS/Windows
environment. Refer to Appendix B, I/O Operating Environment.
