force network card 100 mbit

Hi,
i want to force the network card on my linux redhat 7.2 to 100 mbit.
It isn't an eepro100, so the way to do it didn't work.
In the /etc/modules i have this entry.
alias eth0 3c59x
Usually i add this entry:
options eepro100 options=0x30
in the /etc/modules but in this case didn't work. (of course i replaced eepro100 with 3c59x)
and then rmmod 3c59x
This is the output of my mii-tool command:
eth0: 10 Mbit, half duplex, no link

Thanks in advance
Tarek

Howdy,
The easiest way to set up your card is to download the 3c59Xcfg.exe program from the www.3com.com support site & drop it onto a bootable dos ( boo - hiss ) floppy disk. This sticks the settings into the eeprom. The more graceful way is to insmod with
options=4 full_duplex=1 as the options but I don't know if they can be applied using your modules.conf or not.

PS - at least your 3c590 will do 100Mbit - mine must have come in on the ark as it only does 10 :o(

Hi Tarek,

Check that the port of the switch is properly configured. Do not hesitate to force it at 100 Mbits/sec, full duplex.

Then, I guess both the switch and the host ethernet adapter will negociate 100 Mbits/sec full-duplex.

If it does not work, try to force it in start/stop scripts using mii-tool.

Good luck.
