The 3c90x driver is not present in the installer {instimage|hdstg1.img|netstg1.img|stage2.img}/modules/modules.cgz. Therefore, 3c980C cards are not found by the installer. The driver is present in the /lib/modules/* directory after installation is complete. If it cannot fit on the bootnet.img, please include it in the hard drive and CD-ROM-based installs. The corresponding entry needs to be in the installer kudzu PCI table as well.
it is also not present on the current beta drivers disk ... this issue has been assigned to a developer for further action ...
Driver added to nfs/cd installs -- will show up on either bootnet.img or the drivers.img (depending on disk space available)
