Hello Install Windows 7 and I cannot install the Driver of NETWORK CARD 3Com 905c-tx, already probre with 3c905c_4_41.exe and 3c90x1.exe but I do not work, someone knows since. I need help to install the drivers of network Card?Thank you.

That driver was not supported in Vista either. If you search the internet for getting it to (sort of) work in Vista, it may work ok in Windows 7. Really though, you need to move on. 3COM has not made or supported that card in many, manyyears. A new desktop network card costs 15 USD.Ned Pyle [MSFT] - MS Enterprise Platforms Support - Beta Team
