and if someone have a patched vbe grub or grub2 on floppy image. Wiki links are dead.
I want to switch to vesa mode with grub...
Pached grub
Re: Pached grub
Hi,
AFAIK, you don't need a patch to use VESA with GRUB2. My installation (v1.99) has a module called vbe. See the multiboot 2 specification for details of how to specify the correct tags to switch mode.
Note: You still need to handle the situation where the hardware doesn't support your requested mode.
Cheers,
Adam
[edit - when I say multiboot 2, my version of the specification is labelled 1.6...]
