when choosing the eepro100 Ethernet driver from the drvnet.img installation disk, it fails to load because of unresolvable mii symbol.
Workaround: select the eepro10 driver (should fail to load, unless you happen to have such a card as well), then select the eepro100 driver.
Hrmm, selecting eepro100 again works too. Not 100% sure what's going
on here off the top of my head.
Haven't seen this reported again, so assuming whatever the cause was
has been fixed in newer releases.
