AX = 1002h CH = FFh (pre-read required) CL = buffer type (here FAT, DIR, or DATA, see below) AH:DX = 24 bit sector number
Return:
ES:SI -> buffer control block
Notes: This private function is called internally by the OS kernel to ask the FDOS to find the corresponding buffer. By using the INT 2F/AX=1001h FDOS hook, the call can be intercepted by external system components such as the DELWATCH TSR.. This function must under no circumstances be called by applications!
