另:BIOS中断int13h,ah=42,输入参数,si指向下面这个结构
Format of disk address packet:
Offset Size Description (Table 0249)
00h BYTE 10h (size of packet)
01h BYTE reserved (0)
02h WORD number of blocks to transfer (max 007Fh for Phoenix EDD)
04h DWORD -> transfer buffer
08h QWORD starting absolute block number
其中08h处 block是指扇区吗?还是一个block=2sector呢? |
