这项功能是用来确定硬件配置. 电话号码的功能,以这个基地的功能得到如下表:
Value |
Description |
00H |
Enable prefetch |
01H |
Disable prefetch |
02H |
Set maximum PIO transfer mode |
03H |
Set PIO mode 0 |
04H |
Set default PIO transfer mode |
05H |
Enable INT 13H DMA maximum mode |
06H |
Disable INT 13H DMA |
DMA的方式之一,因此选择互不相条残疾或是指定的DMA装置或装置,所有条残疾的DMA控制器和选拔

Call with: AX = 5001H
DL = Drive number
ES:BX = Command packet (See the Table in
comments)
Return: If Function Successful,
Carry Flag = Clear
AH = 00H
If Function Unsuccessful,
Carry Flag = Set

功能5501h(0x5501)-->讯(联营st01/st02)
Call with: AX = 5501H
DH = Number of bytes to transfer
DL = Drive Number
ES:BX = Buffer for results
Return:
ES:BX buffer, filled with the Inquiry results.

这项功能是用来派遣调查. st01/st02BIOS中的成败并不返回任何迹象的功能,因此必须假设所有指令都获得了成功.
<永远的BIOSst01/st02地图后其开车开车不改变以往的BIOS的BIOS驱动指望在0040h:0075h. 该司令部指挥调查是一致的接口
