直接从MSDN上摘下来的,懒得翻译,反正这点英文应该难不倒各位的。
另外,我曾经很武断的说在主引导区内没有INT13的扩展调用,在此向
被我误导(如果有的话)的同志致以诚挚的歉意
Check Extensions Present
Entry:
AH = 41h
BX = 55AAh
DL = Drive number
Exit:
carry clear
AH = Major version of extensions
AL = Internal Use Only
BX = AA55h
CX = API subset support bitmap
carry set
AH = error code = 01h, Invalid Command
This function is used to check for the presence
of the INT 13h extensions for a particular drive.
If the carry flag is returned set, the extensions
are not supported for this drive.
