On our Alphaserver 400s running DU 4.0b we have ATI Mach64 ISA VGA cards.
The documentation for the Alphaservers has a brief section on using isacfg
where it specifically says (on page A-18):
-slot <slot#> Allows you to enter a unique slot number for each ISA adapter.
You can assign the numbers in any order. The slot number does
not relate to a physical ISA adapter position in the
motherboard.
We changed the cpu board on a crashing system, and after that the (previously
working) Mach64 card stopped working. At boot time the error was displayed:
Oct 22 03:35:14 mysys vmunix: no graphics console driver configured
Oct 22 03:35:14 mysys vmunix: generic console support installed: using VGA
and the following showed up in the syslog.log:
Oct 22 03:35:11 mysys syslogd: restart
Oct 22 03:35:47 mysys syslogd: /dev/console: I/O error
Examination showed that the isacfg parameters on the cpu board with which
the Mach64 card worked were:
slot device handle
7 0 MACH64 Singleport Yes
and the isacfg parameters on the cpu board with which the Mach64 card did not
work were:
2 0 MACH64 Singleport Yes
When I went in and changed the "2" to a "7", the Mach64 card worked on
reboot. Obviously, the documentation for ISACFG, quoted above, is wrong.
Has anyone else encountered this and come up with more information?
I ask because there is a DE200-LE on this system which also has different
ISACFG entries between the two cpu cards, and the DE200-LE is not working
with the replacement cpu card, so once things settle (this machine has been
crashing, we are trying to get it to stop before changing too many things)
I'll probably change the ISACFG entry for it too - once again, the only
thing that differs is the slot number. According to the manual, however,
this is voodoo!!!!!!
TIA...
