SCSI isn't recognized

[The Sutherland's <tsland@worldnet.att.net>]

Dear Users,
    I just tried to install Debian 2 from CD-ROM on
my machine, I got the Debian boot prompt, pressed enter without
parameters, linux began to load then I kept getting the following messages
repeated over and over (one hour) until I just shut the computer off:
    SCSI host 0 abort (pid 2) timed out-resetting
    SCSI bus is being reset for host o channel 0
    SCSI host 0 channel 0 reset (pid 2) timed out-trying
harder
    SCSI bus is being reset for host 0 channel 0
    (scsi0: -1:-1:-1) Bad scbptr 16 during SELTO
    (scsi0: -1:-1:-1) Referenced scb 255 not valid
during SELT0
    scsiseq = 0x5a SEQADDR = 0x8 SSTATO = 0x15 SSTAT1
= 0x88

As I said, this message would repeat forever, if I let it.

    Hardware, with win95 installed:
        3 1/4 floppy
        SCSI ID #0: Seagate ST51080N HDD
        SCSI ID #3: NEC CD-ROM: 461
        SCSI ID #4: Iomega Jaz-1G
        SCSI ID #7: AHA-2940 U/UW Adapter
                No other devices installed.
                Note: I did get the Debian boot prompt where I began loading Linux, then I got the above messages.
    Help!
    Thanks,
            Tim Sutherland
