I played a bit with the box today (sorry, had no chance to capture the du=
mp, =
someone 'borred' my cableset, and the cable for my console terminal is a =
special one...), but it occurs while scsi scan.
After disconnecting both disc drives
Vendor: IBM Model: MXT-540SL Rev: J1.5 (id 0)
Vendor: SEAGATE Model: ST32430N Rev: 0510 (id 1)
the boot up works without panic, but i dont have anything to install on. =
The =
tape drive (Vendor: ARCHIVE Model: Python 25501-XXX Rev: 2.26 (id 6)) =
is =
still connected.
Perhaps the delay after scsi bus reset to begin of inquiry is too short? =
[I =
only know FreeBSD on i386, and there's an kernel option for this delay)
(tomorrow i'll take some tools to university and try to give ID 5 to the =
main =
disc, perhaps i'll be lucky then)

The board is ok, running under SysV68k stable and under Lin*** kinda stab=
le =
(except for commiting suicide after 14 days uptime...)
BTW, i tried another board (MVME 167B , 16 MB non ecc ram, 68040/25, but =
not =
configured [pressed abort while poweron:)]), and after booting kernel fro=
m =
tape i got the bug prompt again. no error, just "Entry point is 0x0x0800"=
and =
"bug167>". Strange!
=
I hope to get it running soon ... :)
and after that i'll try to use some of our VME-Bus periphials
