pmode bootloader qx2

[Ozguxxx]

Hi all people... Another qx about pmode bootloader(It might be very silly but forgive me, I am a newbie): should a20 line be activated by a bootloader that changes processer into pmode? Why. 10x to everybody...

ok.... what do my mean by "qx" what does that mean? Oh yea, and what bootloader are you using?

qx=question. I am trying to write my own bootloader. In fact it is like copying and pasting some of the bootladers that I could find on the net, however I am modifying some code of these in order to improve the code. I think I could not find a way to enable A20 line, in fact I am looking for the robust source code (Also small) for enabling A20 line. ;D
