Hi!!! I need your help, because I have problems installing the driver of a 3com ethernet card. The erros said:"Problems with 3com 3c90x adapter driver, this part of the computer is not working" (something like that. I'm workin in a NT System, and try to install other driver but never works, could you help me. thanks.

Be aware that 3com use different drivers for their cards, make sure you have used the right driver....If the card is not new, make sure it hasn't been set before to a conflicting irq or address.

I know this comes almost a year after the fact but.... late is better than never!!
