I've got a port of the NetBSD MI driver in progress that should fix the stability problems. This card uses the i82586 or i82596 ethernet controller. The Intel EtherExpress 100 ISA (and EISA/PCI refered to as the "EtherExpress Pro/100A") are not supported. The EISA/PCI adapters use the i82556 chipset which is somewhat different from the i82557-9 chipsets. > These cards use a National Semiconductor chip that was used in a few > Cisco routers as well.

I'd love to read over them. -- | Matthew N.
