SCSI HEADACHE

[finger51]

Hi All!

I've got a Seagate SCSI drive plugged into an adaptec scsi controller. When I tried rebooting I get a "no operating system" message just after the BIOS goes through the start up. The BIOS sees the SCSI card and that there is a drive on it, but then dies.
I think whats happening is the system is trying to boot from the SCSI drive but can't and just freezes.
I have also gone into the BIOS and made sure the "boot from SCSI" is turned off. I have tried a miriad of jumper settings and have tried ID's 1,2,4,7 always the same response-"no os"
I think the last thing I need to tell you is the drive is labled "C:" Is it possible to change the drive letter with PQmagic or something similar?
My system:
P200
Asus mobo w/ award bios
196 megs-o-ram
2 gig ide (with NT sys files only)
13 gig ATA-66 plugged into a Promise controller card (with all my programs on it)
adaptec AHA-1540 SCSI controller


Thanks!

I should have added- I don't want to lose any of the data on this drive so just an outright format is not an option.

found a site for info on the controller card-

ftp://ftp.adaptec.com/pub/BBS/installguides/aha1540cp_ig.pdf

page 11 has some info at the note on the bottom of the page about having more than one host adapter and disabling the bios of the the one you DONT want to boot from...
1st ?
will I be able to use the drive with the controller BIOS disabled?
2nd ?
how do I disable that bios?
