Is INT13H (non extended) capable of accessing drives with more than 16 heads per cylinder?
问题 I know that you need the INT 13H extended functions to access drives over 8GB in size. This question refers to standard INT 13H, function 02H. I also know the old 504MB hard drive limit was a result of: 1024 cylinders x 16 heads x 63 sectors x 512 bytes = 528,482,304 bytes. But was this hard drive limitation caused by Int 13h itself? Is there any particular reason the head number was limited to 16 when there is an entire byte of space (dh) for the head number? Obviously later on the standard
