help with backtrack3 and ophcrack
 

If I boot either ophcrack or backtrack3, my computer locks up and the scroll lock and num lock keys on my keyboard sit there and flash endlessly until I reboot my machine.

I'm booting a live install off a usb thumb drive through grub.

I have puppy and DSL on it too, and those boot / work just fine.

Any ideas? I've tried booting it in a virtual machine but got the same outcome (minus the flashing keyboard lights)

The last few lines before it freeze read (in the boot sequence that shows a bunch of txt)

The first line (sexy-python), there are dozens of lines just like it but with different .lzm files. They all have either i686 or i486 in them somewhere.

Have you tried any switches at the end of the boot line for either distro?

For example linux noapic noacpi no=apic no=acpi

Nope. What is that suppose to do?

My menu entrys are as follows



EDIT

I got backtrack 3 to load using the following menu.lst entry. I'll try something similar with oph crack.

And if I change it to whats below - I get a graphical boot (there is a background image). Can someone explain to me why and what the difference is?....how it works? As well, can someone give me a quick rundown on the ramdisk size? Say I'm using a system that has 512 ram....or maybe even 768 ram, what would be the ideal ramdisk size?
