INT 10H interruption does not work properly.

Hi PDOS team,

I find that INT 10H does not work well in some mode:

I put in boot.S the following lines:

mov $0010,%ax
int $0x10

, which sets 640*350 with 4-bit color. However, it starts with only mono-color (2-color) console.

Actually it works well in 13H mode(320*200 256-color). But why the 10H mode doesn't work properly? Do I miss something?

BTW, great thanks for publishing such a good OS lecture!
