Re: Newbie trying to learn raw x86 asm



Anti Vigilante asked:

I'm on a Debian 686 box. I want to learn ASM not just through int 80
which Linux uses but at the lowest level before machine code to do
programs like how grub lets you play space invaders at boot up.

Raw x86 Asm coding ??

1. RTFM
read the CPU-manuals from AMD and Intel.
You'll find much more details of how a CPU can work far away from
what any tutorial may be able to show you.

2. INT 80h means the API of L'unix only

3. 686 may mean nothing more than: post PIII/P4/K5, you may not
find anything less than AMD K8 or Celeron on the market yet anyway.
Current standard is 64-bit capabile Multicore with Hyperthreaded
I/O-channel access, even most OS will still use only 32-bit mode
(backwards compatibility) and run 64 bit mode in rare occasions.
