[SOLVED]Grub + vga option

I've always had the vga=795 option added to the kernel line in /boot/grub/menu.lst. Since today, this doesn't work anymore although I never changed the config file. I get this error:

probing EDD (edd=off to disable)
undefined video number:31b
press <enter> to see video modes available, <space> to continue

<enter> shows me the modes available, but using those options gives me a totally messed up screen. <space> just boots as if there were no vga option.

This is my menu.lst file:

# Config file for GRUB - The GNU GRand Unified Bootloader
# /boot/grub/menu.lst

Re: [SOLVED]Grub + vga option

You can try to add "edd=off" to your kernel line.

Heh, I feel so stupid. That actually worked!
