INT 0x1E disquette paramaters

Post by spiner900 »

Hey, I would like to know what is the utility of the INT 0x1E. I know this the address of the diskette parameters table but why some boot sector change the value in this table ?

It makes disk operations faster. Modern floppy drives can work considerably faster than written in BIOS tables therefore one should change the parameters affecting on the speed (only two parameters).
If you have seen bad English in my words, tell me what's wrong, please.

There is this thing called Google. Then, there's this thing called Ralf Brown's interrupt list. Then, there's the explanation of the int 0x1e paramater table.

Really.
