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

[courtneycthomas at bellsouth.net (Courtney Thomas)]

Attempting to bootup a live Isolinux iso on a Dell Latitude C810 portable,
I'm getting a screen scrambled with almost impenetrable horizontal lines
though I can see the blurred GUI 'behind'.

I'd like to mount root on a USB jump drive.

What would be a manually entered [at bootup] command that should
get this thing going, please ?

I've tried [a guess] of :

    /boot/linux append root=/dev/usb0 video=ask panic=10 

but get nothing but kernel panics.

By the way, what's a framebuffer all about ?

Happy New Year !
