<p><b>Notes:</b>
|
|
The return values are identical to the standard INT 13/AH=08h, but the
|
|
number of drives is not limited to 2, so.
|
|
Scanning all possible drive numbers with the Read DASD Type call
|
|
(AH=15h) should generally be preferred to determine the number of
|
|
drives attached to the system.
