[SOLVED] Int 13 08H return values

Post by qw »

Hi everybody,

According to Ralf Brown's Interrupt List, int 13H 08H returns the maximum cylinder number, the maximum head number and the maximum sector number. In CHS adressing, the cylinder and head are zero based and the sector is one based. This should mean that the number of cylinders is the maximum cylinder number plus one, the number of heads is the maximum head number plus one and the number of sectors equals the maximum sector number.

Could someone confirm this please?

I confirm that (and Wikipedia does so, too: INT 13). :wink:

I'd never expect to find INT 13 on Wikipedia... What's next, INT 13 in the Encyclopedia Britannica? Thanks for your reply!
