We have one in use from Cogent (now: Adaptec). They have a family of 4 port PCI-cards that all use the DECchip controllers. We use the 4x BNC (10Mbps) model but you can get up to 4x 100Mbps fullduplex. The card currently runs in a linux box but I had it on FreeBSD too and it works fine. I don't know current prices. Look at <http://www.adaptec.com/products/overview/cogentquart.html>; Potential Problems: - The board uses a PCI Bridge. Older BIOS versions often do not initialize these chips properly. - Two cards _should_ be no problem, but you can only be sure about that after a test (another field for BIOS or PCI-Driver bugs). - The controllers are longer than typical PCI-Boards - many Mainboards have the CPU or SIMMs in the back of the PCI-Slots so you can't plug in two long cards. ciao, Martin. --
