detecting scsi device

Hey guys,

I have a scsi drive that I am using as my swap space but I am having a problem; that is that the computer will not detect it since I installed my new harddrive. After I put it in, the computer gives me a new error (I believe it is durring post) which I believe is just relevant if you are booting from it (I'm not). The message it gives me is:

No scsi boot device found

Also it tells me:

SCSI BIOS not installed



Now could it be because I do not have a terminator on the external port? If that is so why did the scsi drives work before? Do you think that this is why I am getting this error that sometimes appears in :

scsi1: PCI error Interrupt at seqaddr = 0x8

scsi1: Data Parity Error Detecteddurring address or write data phase

scsi1: WARNING WARNING WARNING

scsi1: Too many PCI parity errors ??observed as a target.

scsi1: Some device on this bus is generating bad parity.

??scsi1: This is an error *observed by*, not *generated by* this controller.

??scsi1: PCI parity checking has been disabled.

??scsi1: WARNING WARNING WARNING



Then this segment repeats itsself every few seconds with the '8' in the first line changing to a 7 or 9.


You know, I was relating the data parity error with the fact that my SCSI was
not working, but as I looked at it I realized that I wasn't reaading it
right.

line 6:

scsi1: This is an error *observed by*, not *generated by*, this controller.


So now my question turns into: how do I figure out what is generating the
error?


and


Why will it not see the scsi drive?
