50 pin scsi won't boot

By notned ·
have an old 486 powered server with two scsi hdds one at 200meg and the other at 1gig with a cdrom.
the bios detects the 1 gig hdd but not the other
then can't config for system to load Win NT 4.0
server,the system won't go past the bios am setting up a small home LAN and this small server should act as a firewall, i'm hoping!
any help would be mucho appreciated!

The immediate things to check:

SCSI IDs. Make sure these are unique and assigned correctly. You should assign ID 0 to the device you want to boot from. The CD is traditionally set to 3, but this is not by any means a rule...just a common practice.

Check the jumper settings on your SCSI devices. You may need to hunt around a little on the internet if you don't have manuals. I have found SCSI devices to pretty persnickety about their jmper settings.

Open up your SCSI card's control panel(CTRL-A on Adaptec, others have their own key combo. It should show this on the screen as the card is initiallized). Check the settings and make sure they aren't out of the acceptable range of the device. That old 200mb drive may not be able to function at the speed your card is trying to run it for example. You can tweak the settings and see if it is then recognized (I usually try the lowest settings then move up if having these kind of problems).

Check your termination. If a device in the middle of the chain is terminated, nothing after it will work.

Check your cabling. Make sure everything is securely fastened, the cables are good and all devices power up okay. Are you using all the devices on the same cable? If not, then make sure your card supports the interfaces you are using being used simultaneously.

Try removing all but one device. Then see if it is recognized. Add a device. Test again. I know I'm repeating myself, but make sure you have the scsi IDs correct. I have seen this cause more SCSI problems than every other problem combined....

If none of this helps, let me know and I'll be glad to assist further! Good Luck!
