中国科学院43(0x13)

功能-2402(0x23或35)-->确定控制器特征登记(聚苯乙烯及PS/2,硬盘)

Call with: AH = 23H
AL = feature number
DL = drive number

Return: If Function Successful,
Carry Flag = Clear

If Function Unsuccessful,
Carry Flag = Set
AH = Status

评论:

这项功能是用来确定控制器专题册.如果成功的功能是很清楚,如果不成功携带国旗旗开携带登记、申报地位啊.


中国科学院43(0x13)

功能24h内(36或0x24)-->确定多重转移模式(硬盘、聚苯乙烯及PS/2)

Call with: AH = 24H
AL = number of sectors per block
DL = drive number

Return: If Function Successful,
Carry Flag = Clear

If Function Unsuccessful,
Carry Flag = Set
AH = Status

评论:

这个集多种功能是用来传递方式. 如果你想要扼杀了多次转移模式,确定若干部门至0. 块大小的最大值(如2,4,6,8和16等等)取决于固定式磁盘驱动器.

商品储存在第15字节的固定磁盘驱动器的参数设定表,邮寄(电力自我考验). 在0040h字节的地址:0074h定运行状态. 硬盘专题价值观ps/1人数已表列如下:
