Can any one tell me where can i get the INT table and which software can i use to compile and
run programs containing INT requests..

1) why are you posting this in the MASM32 forum? It should be in Main, or perhaps even The Heap (not very win32 related, is it now)

2) I assume you want to do 16bit code? Google for "ralph brown" "interrupt list", that's probably the most comprehensive list around. If you want to use masm to do 16bit dos programs, you will need the 16bit linker - there should be more than a few posts here on this board telling where to get it, so do a board search.

The Ralph Brown's Interrupt List is downloadable from here:

An html version is available here:

Some information on how to use masm to do 16bit dos programs are available in this board, just do a search.

Here one post where you can already find some informations:

You really should have let him find those URLs himself, cip.

Probably you're right, but as I had them in my bookmarks it was just a copy/paste... :grin:

Moved it to heap,

if it is old DOS 16 bits related i guess

Else let me know and i will eventually move it to Main,

You will have to make a KMD if you really want to use ints in win32
but even so it will be really hard as INTs are "virtualized" in Windows kernel
(well there are other "hacking" ways but we will not discuss them here)

Randall Hyde's web site offers a lot about 16-bit coding:

One thing I've been wondering about is how windows takes care of drawing on the screen and other low level things like that. Is windows using interupts deep down in the kernel? I haven't done any DOS-assembly-programming so I don't know of any other method to access hardware.

In Windows, most hardware operations are carried out using vendor-supplied drivers. However, it has the capability to run the BIOS routines (in Virtual 8086 mode) to access strange hard disks for which it doesn't have a driver. Interrupt 20h is used within Windows operating system components and drivers to dispatch functions in other components, but the INT instructions are replaced with indirect calls or jumps once they are called, for speed reasons. I don't know how Windows NT works, though.
