AFAIK, there is such situation: There was many NetFlex models of network controllers NetFlex-L : onboard ethernet controller made on AMD PCnet chip (on which was built NE2100 card) built-in on old DeskPro's XL, Prosignia VS, 200, 300 and 500 FreeBSD driver - lnc0 NetFlex-3 P/E : Old P-PCI/E-EISA controller, was made when Compaq have not Netelligent division. Have module architechture based on TI ThunderLAN chip and removable media adapters for 10BASE-T 100VG and 100BASE-TX (one at once) Supplied on Proliant 1500, 4500 and 5000 servers and separately FreeBSD driver - not available yet Netflex-2 Dual Port controller based on TI TLAN chips too; rare thing FreeBSD driver - not available yet Latest Netelligent solutions built in Deskpro 4000, 6000, Proliant 800 , 850R, 2500, 6000 Same based on TI TLAN chip, available as onboard, and PCI card options. FreeBSD driver - not available yet The main thing that all Compaq boards based on TI TLAN in use the same set drivers. i.e. possible to use 1.5 year old drivers under NW or NT for latest boards without any probs.
