You don't know what you're talking about, my friend. The Int 13h driver is supposed to issue int 15h, ax=9000h, which will indicate for a multitasker that it has to wait for the I/O operation to complete. Consequently, the (irq 14/15) ISR is supposed to issue int 15h, ax=9100h to finally indicate that the io operation is finished.

The MULTITASKER is supposed to HOOK into the int 15h chain, but the Int 13h driver must CALL it. Is that so hard to understand? Any other behavior simply doesn't make any sense.

Well, since I'm a gentle person I'm hereby making you a offer to teach you the basics of the ROM-BIOS. Will cost you nothing, at least the first 2 lessons.
