I have the same problem on a dual PIII 733, a single 733 and a P4 2.4Ghz, when booting with the 2.4 kernel i just get a black screen and that is it. THe machine is locked up and you have to use the power button to reset it. The P4 and dually will work with the 2.6 kernel, but I really need to use 2.4. I have tried new cd's and a bunch of cheat codes. Any suggestions?
