I would like to get my new-fangled 64bit-but-can-handle-a-32bit slot
PCI SCSI controller supported by BSD. Supported, that is, in a 32bit
I have a Compaq 1600R/550 with a single CPU. I (stupidly) bought a
nice 64bit PCI SCSI controller for it without checking if it was
supported and I stuck it in a 32bit slot.
Now, when the machine is coming up, you can see that the card is
recognised. The problem appears to come up when OpenBSD sees that it
is a 64-bit card, but doesn't realize that it is in a 32bit slot.
Oh, and it workes under FreeBSD.
I can't send dmesg output right now because I don't have
it and the machine is about to go into production. It is possible
that I could get it in a few days, though if I can take our other
1600R offline for a bit. It isn't yet in production.
What I'm wondering is if anyone knows if OpenBSD can deal with 64-bit
cards in 32bit slots in general. The driver for the board (ncr.c?) is
based on FreeBSD, but seems to have drifted quite a bit from the original.
Enough rambling. Anyone got any ideas before I scrounge up some
This Unix stuff make DOS look like a three-piece tinkertoy set.
