    Default Model 8595 Error "01291300 DMA BUS TIMEOUT"

    So I have an 8595 with an upgrade DX2-66 Complex in it, and I am trying to boot from the Reference disk, when I do it errors out with:

    01291300 DMA BUS TIMEOUT

    Odd thing is, I can boot into an OS, then if I do a warm boot from there, it boots to the disk just fine. While it was up, I ran through all the diagnostic stuff, and everything checked out fine, no failures. I then went into the SCSI tools (as I wanted to get the IDs for the SCSI drives in there) and as soon as I selected the option I dropped to black screen with that same error.

    Thinking this might be the SCSI controller (An "OLD" Spock controller) and replaced it with a Enhanced Differential SCSI Fast/Wide Adapter (I think this is called the Corvette?).

    Of course the machine complains that the adapter configuration has changed, and it'll then tell me to insert the reference disk and press F1, as soon as I do this I am greeted with the DMA bus timeout message.

    I created a second Reference disk on a new disk, and the problem continues.

    Anyone seen anything like this?

    Long answer in comp.sys.ibm.ps2.hardware , but just pull the Boca, the 3c529 is reliable in Pentiums.
