C. General Troubleshooting Tips
Most controller errors are traceable to external factors, such as conflicts with other installed
cards, bad or incorrectly configured drives, loose cables, improper SCSI termination, or other
installation errors. To troubleshoot SCSI problems, try simplifying your hardware
configuration by removing some devices from the system and then adding them back one at a
time. For slow external SCSI devices you may also try to set the “Sync Negotiation” to “No”,
i.e., Async, or decrease the transfer rate to a lower speed within DC-395’s PCU.
Look for the latest information on Tekram SCSI Controllers as well as the newest drivers on
the Tekram web site at http://www.tekram.com or ftp://ftp.tekram.com. The following are
general guidelines for some specific error conditions:
1.
The error: "WARNING: 64Heads, 32 Sectors Parameter is expected...." pops
up after the DC-395 BIOS:
•
The most likely cause of this error message is using the DC-395 with a drive that has
been formatted with a different controller. Try toggling the setting:
Greater Than 1G
Support
in the PCU.
•
If the above solution does not work, you must boot from a floppy and run FDISK.EXE
to delete the partitions. Then, re-Fdisk and Format the drive to make it compatible with
the DC-395.
2.
The BIOS Message of the DC-395 never appears on the screen:
•
Check if you have any other cards in the system that could be using BIOS addresses
C800 - DC00. If you do, one of these cards may be conflicting with the BIOS of the DC-
395. Take out the suspect cards and see if the BIOS for the DC-395 comes up. If it does,
change the address on the conflicting card.
3.
The <<< Press F2 or F6 …>>> BIOS Message is missing after BIOS upgrade:
•
After BIOS upgrade there will be no <<<Press F2 …>>> message shown along with
DC-395’s BIOS message during next bootup, since the setting for “F2 or F6 Function
During Bootup” is set to “Disabled”. To enable this display you need to execute
\DOS\UTIL.EXE from the DOS/NetWare driver diskette and set the “F2 or F6 Function
During Bootup” in “Set Adapter Options” to “Enabled”.
4.
When the system attempts to boot, the error: "Missing Operating System"
pops up:
•
If you are using a drive that has been formatted with a different controller, try changing
the
Greater Than 1G Support
option in the DC-395 BIOS. If you still get the error, you
must re-Fdisk and Format the drive to get it to boot normally.
