Fist off, sorry if this makes it two posts. Blame it on windoze.

I have a box running Linux Mandrake 9.0 and a 3Com
3C905B-TXNM card and the 3c59x driver. The card is
working and I can connect but for some reason I am
unable to get the card to function at 100Mb full-duplex.
Not even by messing with the settings in Drakconf.

The card is plugged into my Linksys BEFSX41 firewall
which does support 100BaseT FDX. This machine is
in that mode now.

It has been a very long time since I dealt with Unix.
Gotten used to running my head into billware.

Anyhow, any ideas?

Never mind. Figured it out.

Seems the configurator in Mandrake stinks.
Simple solution is to edit
/etc/modules.conf (isn't the standard conf.modules??)
Remove any stray "options" lines, then put in
options 3c59x options=12

wash, rinse, reboot

whee!
