Hello,
i recommend this size optimized exit code for your os 
Code: ; they are the same in size, but the right side won't exit on esc if ah<>0 ; 5 bytes (7 with int 20h) ; i will not take any responsibility for any hardware damages ; this code can cause ; i recommend using the right side with dec al, however its all right if ah=0 ; MATRIX org 256 mainloop: in ax,$5f ; in al,$60 sahf ; dec ax jnc mainloop ; jnc mainloop int 20h it does weird things

>>>it works fine, until you press a key.
All is correct Meanwhile, IRQ1 is used for return in debuger...
Because OS is at an early stage of development... no_int20: ; IRQ1, Keyboard cmp al,0x21 ; Controller: i8248 jne no_int21 in al,0x60 mov al,0x20 ; EOI out 0x20,al ; Return to AXE debuger... mov al,0xFE out 0x64,al >>>i recommend this size optimized exit code for your os  interesting code... |
