I've taken the machine back to the shop - The MediaGX cpu (which I previously knew nothing about) scared me... the lengths people go to so that they can produce something a few $$$s cheaper... I've replaced it with a machine w/ an Intel chip (FOOF & all). Interestingly enough, the PCIC probes as a VLSI 82C146 on this machine too, and my 3c589c seems to be misbehaving in the same way (IRQs don't seem to work) - but I can see psm0, so it just seems to be an interrupt thing. Of course I'm still on 2.2.6-release (no timers mentioned at boot time, and no sig 24s). I'll try to cvsup to -current from my other machine over a ppp link if I can't get the NIC to respond tonight. > -- > Poul-Henning Kamp FreeBSD coreteam member > phk@FreeBSD.ORG "Real hackers run -current on their laptop." > "ttyv0" -- What UNIX calls a $20K state-of-the-art, 3D, hi-res color terminal -- Brian <brian@Awfulhak.org>, <brian@FreeBSD.org>, <brian@OpenBSD.org> <http://www.Awfulhak.org> Don't _EVER_ lose your sense of humour....
