Installing on a system with Tyan Tomcat IV Dual P200MMX motherboard with a LinkSys Ether16 skips the network configuration part and goes directly from lilo installation to timezone configuration. Also, the image is missing from the Printed Installation Guide for the network configuration. (Figure 4-10) I was able to finish the install and configure the network card through linuxconf so the system works, but it is just skipped in the install.
The installer will skip network configuration if it does not find a network device in the machine. I think the Ether16 is an ISA card, therefore it cannot be autoprobed by the installer and this is why the network config screen was skipped. The way around this is to boot the installation with "linux isa" at the boot prompt. Doing this will force the installer to ask you about any hardware in your system which was not autodetected and you will be able to inform the installer about the NIC. Once that is done, the network config screen will come up during the installation.
