Issue: RedHat 7.0 Beta 3 3Com 3C575 not supported Dell Portable C600 Video ATI 3M Audio Maestro3i NIC PC Card 3COM 3C575 32MB Ram. When attempting to do an NFS install 3Com 3C575 not supported .
Did you boot with pcmcia.img? I had no problems with a cardbus 3c575 (specifically model 3cxfe575bt) doing an NFS upgrade on a Sony Vaio using pcmcia.img on beta1-beta3. Or is there "yet another version of the same 3com card that needs to have its name recognized?" :)
The problem was deduced to a bad network connection. It is working now. Thanks
