It's a 486dx2/66 on an EISA motherboard (not sure whose, I can check if it's helpful) with 16M ram, a MAXTOR 639M SCSI I drive, a BusTek 742a SCSI controller, a plain jane vga card, and an NE2000 clone. In the past we were running NetBSD and had hangs with this same NE2000 ethernet card. Switching to a WD ethernet card stopped the hangs but it would still panic and reboot sometimes. I want to order an SMC card and see if it stops. Speaking of which, do you sell them? -matt -- Matthew C.
