Re: unable to install two network cards

it appears both cards are trying to use the same i/o address. some older
network cards required that you firmware-set their i/o port via a
utility provided from the card manufactuer (lots of the older linksys,
smc, and 3com isa cards were like this). you might try getting this:
http://support.3com.com/infodeli/tools/nic/3c509/3c5096.1.htm software
package from 3com, booting up to a minimal dos prompt via a bootdisk,
and modifying the cards' default settings.
