BIOS Interrupts

Orkie · 04-20-2005, 12:31 PM

Does anybody know where I can get an OS independant C library (which I can compile into a flat binary file) that has a function for calling BIOS Interrupts (and changing the appropriate registers in order choose a function and to pass values to the interupt functions). I don't mind doing this in C but I have no idea how to call interrupts from within C and the same with modifying the register contents.

Thanks

I eventually found an answer through my searching and it is no - there isn't one it would have to be done through inline asm or to link a separate file against it. I wanted to play around with INT 13h (which is the disk routines) but in my research I managed to find the memory addresses or the various devices including disk drives so I can do it through that instead of messing about with the interrupts.

Hi,

I am looking for an interrupt table, can anyone provide a useful link ?
eg.
int 0x10 = Video BIOS interrupt
and etc...
