hi,
We have successfully installed FreeBSD2.0.5 on one of our systems, using
NCR53c810 SCSI controller (on separate board).
Then we tried to do the same installation on COMPAQ Pentium90 with the same
NCR53c810, but integrated on motherboard. Now it looks like kernel.GENERIC
does not see NCR controller, we got no diagnostic about it at all.
Running Linux on this system all seems to be OK with SCSI.
Here is a sample from it's (Linux) kernel bool log:
...

Looks like BSD vs Linux are using different address/io/irq settings (?)
Any ideas/solutions ???
