Windows driver use default setting from eeprom by default. If you impose
other preference it use setted preferences.

It do not work. I used modprobe options=0x204,0x204 but with eeprom card
configured with 100/Full (with 3Com tools) the driver say "cable not
present" or similar (card setted with dhcp).

This is not a big problem.. I'm Italian :)
However we use only bought patchs and the only problem I have is using
Linux.
All I want to do is setting card fixed to 100/Full (all network, about
thousand machines, are setted 100/Full)...
I'm not the network administrator but I don't think the problem is the wire.

Cards are all 3c905c. Follow partial "lspci -vn"
