hmm, is there any way to do this manually, because mandrake 8.2 doesnt have those options under Mandrake Control Center ?

You can edit /etc/lilo.conf and then run "lilo" to write the new settings to the bootloader. I assume the line "vga=" could have some kind of affection to the GUI bootup. Here's my (non-graphic, text-only) lilo.conf for comparison, you can compare it to yours.
