SCSI problem, can't instal Debian

["Reagan Doose" <doose-family@worldnet.att.net>]

I am trying to install Debian 2.0 from a Bootable, SCSI CD.  I have a Dell
Dimension XPS H266 computer with an Adaptec 2940UW SCSI adapter and a 2GB UW
hard drive.

All starts off well, I get the boot prompt, and the system looks like it is
coming up, then I get this:

(scsi0:-1:-1:-1) Bad scbptr 16 during SELTO.
(scsi0:-1:-1:-1) Referenced SCB 225 not valid during SELTO.
SCSISEQ = 0x5a SEQADDR = 0xh SSTATO = 0x15 SSTAT1 = 0x8a

This is repeated forever.

This problem did not occur two days ago when I installed RedHat 4.2, so I
don't think it is a hardware problem.

Any advice on how to proceed would be greatly appreciated!

Thanks
