I installed windowsXP a few days ago and everything works fine except for my 3com 3C509TP ISA networkadapter (Not Plug & Play). It works fine on windows 98 & DOS, but windows XP won't even find my 3com card. I downloaded a DOS based program which sums up all 3com network cards, in DOS it finds my card, but if I try running the same program from windows XP it finds nothing. Does anyone know how to solve this problem?
