next in thread | raw e-mail | index | archive | help
After a confusing sequence of events concerning power spikes which killed
my home gateway, some shuffling of network cards was needed.
An underused machine which for the usual reasons (SWMBO and daughter
insistence) dual boots FreeBSD 5.0-RELEASE and Win98se ended up with a
3c509-Combo card (ISA) which *almost* works. That is, after booting
into win98's 'dos mode' I was able to run the config program and set
the card to not grab IRQ11 for itself, and after a few attempts the
card at least works somewhat in win98.
However, the card does some strange things when I boot FreeBSD.

There is only one network card in the machine, I promise!
The network card at ep0 is then initialized normally, but the network
response is extremely slow, taking literally minutes to scp a small file
like the dmesg above to another machine across a 10Mbit ethernet.
The card performed reasonably as the inner interface on the (now
deceased) gateway running Debian, and the machine and cables in
question performed just fine with another 3com card (the xl
persuation) which was needed more urgently elsewhere and various
FreeBSD releases plus win98 when necessary.
I'm unsure if the real problem is that this card needs some not very
widely known special pampering or if it is more likely that the card
was actually damaged by the power irregularity even if the diagnostic
programs from 3com do not turn up anything.
Any advice on how to proceed would be much appreciated, although
swapping the card for another one (preferably some PCI card or other)
would perhaps be a saner option than fighting with ISA cards these
days.
