AH = 01h DL = drive (bit 7 set for hard disk)
Return:
CF clear if status unchanged CF set if status changed since last call AH = 00h AL = status of previous operation (see #00234 at INT 13/AH=01h)
Notes: This function is nearly the same as INT 13/AH=01h on a standard PC BIOS. The TI's BIOS tranparently performs a number of retries, and an error status is only reported if all of the retries fail. To get the error status if the operation succeeded on a retry, use AH=07h instead
See Also: AH=00h - AH=07h - INT 13/AH=01h
