There is a driver (tulip_cb) that works with the Etherjet Cardbus PCMCIA that comes in the IBM Thinkpad 570. But it's manfid is not in the /etc/pcmcia/config. In order to the EtherJet Cardbus PCMCIA network adapter to be identified, edit /etc/pcmcia/config on the netboot image and add (Author of the following lines: r.scholten.edu.au ) card "IBM 10/100 Etherjet CardBus" # version "IBM", "10/100 EtherJet CardBus", "IBMC-10/100" manfid 0x00a4, 0x0113 bind "tulip_cb" Remake the netboot image and dump it to a floppy. RH6.1 will install itself from the network with no effort!
