either a hex value or a decimal value may be passed.
"0x" is used if you pass a hex value, else value passed will be taken as
being a decimal value.
some basic resolution codes, in decimal, are:
colors bits 640x480 800×600 1024×768 1152×864 1280×1024 1600×1200
256 8 vga=769 vga=771 vga=773 vga=353 vga=775 vga=796
32K0 vga=784 vga=787 vga=790 vga=354 vga=793 vga=797
65K0 16 vga=785 vga=788 vga=791 vga=355 vga=794 vga=798
16M7 24 vga=786 vga=789 vga=792 vga=795 vga=799
Maybe, maybe not. I have several laptops here. Each one produces a different
list of possible VGA modes.
Your actual VGA modes depend solely on your video BIOS. I looked, and I was
unable to find any way to obtain a list of supported video modes from
userspace. The boot time prompt is the only time yu see them.
