used any of computers special micro controllers to do some calculations or non-specific tasks for you in your program (just like normally people use math coprocessor and cpu).
I mean in some undocumented or unusual way, not just programing them to perform normal duties, but something fun and crazy???
if you did, please tell.
cheers mates!
Turnip,
Like mem-to-mem copy via 8237?

Freezer cartridges (action replay etc), switchable silicon-based operating systems and hardware kernels etc.
I worked at a company called Dolphin in South Australia which made a number of products, some of them legally questionable, but all intelligent in design, it was quite educational, and a whole lot of fun.

well thats great no doubt, but its complicated electronics requiring welding and stuff, what i
rather hoped was some tricks about using undocumented microcontroller features in pe or elf executables in 32 bit protected mode.
baldr
yes i meant that kind of stuff, like using dma controller to copy memory to memory.
is this hard?

wasn't very good at it himself, apparently.

Turnip,
That wasn't hard. Using CUDA to factor numbers is much funnier. But nothing compares to custom microprogram update of CPU.

tell me all.
preferably with some code examples.
for ia32 in protected mode.
if its not too much to ask

Turnip,
Sorry, licensing issues. I've sold that code in a whole. Google is your friend.

What? you are talking about dma?
