cant start 9pcfs

[Paul Borman prb@bsdi.com]

I just scanned by cache of 9fans mail and could not find anything
similar to my problem.  I am trying to install a file server (PC).
It has a 3c509 and an adaptec 1542 with a couple SCSI drives hung
off of it.  I built a fs boot disk and then tried to boot from it.
It finds the 3c509 and the 1542, complains about unknown int 7
(I guess it does not like a parallel port?), displays info on the
two hard drives, quickly followed by something about iobuf and
some large negative number, after which it immediately clears
the display and hangs.  I cannot for the life of me read what it
prints before it clears the display.  (Can I boot with a serial
console?)  Anyhow, if anyone has seen this, I would appreciate
any wisdom you might be able to pass on.

Other hardware in the system (not all for use by Plan9) is:

    Maxspeed (does not use interrupts)
    Future Domain SCSI TMC-850 or some such with a CD-ROM and DAT (for DOS)
    ATI Ultra VLB video
    Soundblaster AWE 32
    16MB of memory

Oh, I do not have the Adapatec BIOS turned on, but the Future Domain
BIOS is on.

Thanks in advance.
