Just FYI - I've made a list of the hardware which has worked properly for me, and
you can find it at:  http://www.freebsd.org/handbook/hw.html (along with what other
generally useful hardware info we've managed to get written down).

They can also exist under FreeBSD when you:

	a) Have bad cache RAM
	b) Have a flakey motherboard
	c) Are driving some component beyond its rated spec
	d) Are driving your AMD DX4 too fast (I saw a system that was
	   instability incarnate until it was clocked down from 100Mhz
	   to 75Mhz).

Not that any of these are your problems, but I've personally seen all 4 result in
flakey systems.

Good move.  VLB is to be avoided for a multitude of reasons.

Not so long as you get a PCI disk controller, no.

They're around $220, I think..

I've heard that Tyan motherboards are also noce.

You might want to buy the "Ultra" version of this, which is ostensibly twice as
fast, but it's a sound move to go with the Adaptec in any case.

You're actually better off with a PCI ethernet card, just for general ease-of-use,
but the 3C509 will also work.

Good luck!
