Tried the lspci. Did not see the 3com nic. Switched nics. Still not visible. Installed original nic. Then went into the CMOS and reset everything, then turned off floppy (none installed), changed video from PCI to AGP. Rebooted and everything worked. Posting from it right now. Go figure. I didn't change the CMOS settings. IIRC the current settings are the same as what I had prior to resetting them.

Oh well, at least it's working now.
