About BIOS interrupt 10h? Video?

Expand Post »

Hello!!! I would like to ask anybody can help me with "interrupt 10h". I do everything correct but every time I get a message "Segmentation fault". My code is:

section .text
global _start
_start:
mov ah,00h
mov al,45h
int 10h

When I compile the file into executable file and run it I get the message "Segmentation fault".

Can anybody help me? I use OS: LINUX and compiler: NASM.
Linux is 32 bit installation. If you can`t understand my problem please ask???

The problem seems to stem on the 16 bit intruction set.

By default, the OS will use the 32 bit schema.
