by Hey,
I installed NetBSD 1.3.2 on my Micron XKE laptop with a docking station
with aic-7860 SCSI and de21143 ethernet behind a standard Intel mobile bridge
chip.
The first odd thing I noticed when booting was that the scsi controller and
ethernet controller were assigned the same irq. Could this be because
they're behind the same bride chip ?
After ifconfig and route commands I could see what was going on on the
ethernet but was unable to ping anything, connect to anything, and
my machine was unreachable. Initially I just got arp requests, later ARP
was resolved, but still no connection.
Anyone have an idea what's going on ?
The 'abnormal interrupt' message would indicate that the irq assignment is the
root of the problems. However, there are no options for irq assignment
in the BIOS :(
Thanks.,
Casey
