Hey POLARiS. I recently installed Win7 x86 and as expected my 3C905tx ethernet controller could not be installed. I searched the web and found a driver - the same driver that you installed - but unfortunately the link was dead. Am wondering if by chance you still have the driver for the 3com ethernet controller and if you could forward it to me by mail.

Ive read that for Windows 7 64 bit you have to manually install the driver from win7 integrated list of compatible drivers.

Hope this helps smile
