Subject: How to capture bootstrap oops?

I need some help, I'm new to this. I have compliled a 2.5.39 kernel for my quad pentium pro system and it is oopsing on bootup. Unfortunently, it looks like a good portion of the oops scrolls off of the screen. Since I don't have the ability to hook up a serial terminal, how do I capture this oops so I can report it?

Thanks,

Chris

This might suffice?

[... patch removed ...]

Or try a serial console (if you have access to such a thing).

People also like using digital cameras these days to photograph their oopses
for typing them in later :-)
