[syslinux] Problems with bootable DVD

[Dmitriy V. Volkov]

Hello,

I am using isolinux. I made bootable DVD with RedHat 9.0.
But I have a problem:
on some PCs Linux can install well, but on some PCs it can't install.
When i trying to install on problems PCs it don't show bootable menu and 
apear white screen and I can't do something.
Only reset can reboot PC.

What's the problem?

P.S. I am trying all last versions isolinux.
