}Error the attach img
any help would be great
I have no clue y -- But some thing is written on the screen thats not suppose to be there
this error happens 2-3 sec after "remap done" is shown - if don't call remap its all good so it got to be some thing in that
i commented out the lines in the function one by one and noticed that it happened only if this code is executed
Code: Select all
outb(0x21, 0x20);
