the highest bit of attributes is the "blinking bit" unless you program the VGA card to support 16 background colours instead. check "freevga" document if you want to know more about it or just stick to the 8 first colours for the background.

Hi,
If you're in real mode you can disable the blinking (and enable 16 background colours) using BIOS Int 0x10, AX=0x1003. See:

At least, this is what I've been using...
Cheers,
Brendan
