heya...
I'm making a little os just for the sake of it..and my own pleasure..
I made a .com file for testing
and bootsector compatible to be able to boot it..
it runs/boots quite well so far..
but when I boot the thingy and call the int 16h, ah=01h BIOS routine then the zero flag is always set..no matter if I press key or not..
within the .com file it works perfectely..
any ideas??
thx,
Alex
