Yes. Your simplest option (going from memory here) is to boot off the CD
again, choose the bf24 kernel, skip the majority of the configuration
options, opting instead for mount previous installation, install lilo, and
reboot - then you should be back in bussiness.
NOTE: I'm at uni at the moment, doing this from memory, if anything look
weird, cancel out and let me know, I'll be home in a couple of hours, atwhich point I can actually take a look myself at the menu and give you the
exact instructions.
