Dumb question, but

[Bonez]

I have a rescue disk which I created when installing Caldera 3.1 from CD
this moring. It boots up fine. However, later today I ran an rpm, for
Win4Lin, which apparently altered something with my video modules.

Now, whether I boot from the floppy and choose floppy or hard drive,
everything seems to load until it comes to 'starting KDE' and then the
screen goes black, and I see nothing except an occasional flash of the words
"modprobe, could not find module".... something to that effect.

How can I with my boot diskette get to a command line mode so that I can go
in an investigate what went wrong and why my system won't boot properly?

Thanks,

Scott
