[ale] scrambled screen tryin' to boot an Isolinux.iso, huh ?

Framebuffer is a low-level video thing that writes video bits to video ram
and to the graphics chip.  You may need to try some different video= lines.
I don't know isolinux details so you'll have to dig on their site for
specific settings. But I'll bet that something like video=vga may get you a
working screen.

You will need the framebuffer stuff compiled into the kernel to use it.

AH! You need to spec framebuffer mode like 788, etc. Knoppix has good
details on this.

Found this on http://www.linuxsir.org/bbs/archive/index.php/t-168922.html:

My isolinux.cfg looks like this:

timeout 30
prompt 1
display menu.txt
default 1
label 1
kernel vmlinuz
append initrd=initrd.gz

label 2
kernel vmlinuz
append initrd=initrd.gz vga=788

label 3
kernel vmlinuz
append initrd=initrd.gz vga=791

menu.txt is a simple text file that looks like:

1) Text Mode
2) 800x600 x 16bit colour
3) 1024x768 x 16bit colour

The user just enters '1' if they want text mode, 2 for 800x600 and so on.
