--------------------------------
	Here's one board which does work with AT&T's SVR4 2.1:
 80386-33, Cache (Austec), TI chipset, AMI Bios
It's sold by CUI, 1680 Civic Center Drive, Suite 101, Santa Clara, CA 95050,
1-(408) 241-9170. 16 SIMM sockets too. I found this after testing a bunch of
boards with the AT&T startup floppies; most boards flunked.
