You could look under Control Panel->Add/Remove Hardware and see if the driver is included in the OS' default drivers list by manually selecting the "Network Adapter" category.
I'd say, though, that if the driver isn't listed there, you're probably SOL re: those NICs.
Update-
In W2K's list, I see these:
SMC EtherCard Elite 16 Ultra (8216, 8216C, 8216T)
SMC EtherEZ (8416 in Legacy mode)
SMC TigerCard (8216L, 8216LC, 8216LT)
