我想获取我的硬盘的参数。使用此处描述的技术。
这是显示软盘正常参数的代码:
mov dl,00h mov ah,08h int 13h
这是代码,显示无效的硬盘参数(可能是我的硬盘空间很大(LBA)):
mov dl,80h mov ah,08h int 13h
我写了这段代码:
mov dl,80h mov ah,48h int 13h
代码给出 cf = 1(错误)。我如何解决它?
出错时,AH
应包含错误代码。它以前如何?
拉尔夫布朗的(优秀)中断列表详细说明了它们:
00h successful completion
01h invalid function in AH or invalid parameter
02h address mark not found
03h disk write-protected
04h sector not found/read error
05h reset failed (hard disk)
05h data did not verify correctly (TI Professional PC)
06h disk changed (floppy)
07h drive parameter activity failed (hard disk)
08h DMA overrun
09h data boundary error (attempted DMA across 64K boundary or >80h sectors)
0Ah bad sector detected (hard disk)
0Bh bad track detected (hard disk)
0Ch unsupported track or invalid media
0Dh invalid number of sectors on format (PS/2 hard disk)
0Eh control data address mark detected (hard disk)
0Fh DMA arbitration level out of range (hard disk)
10h uncorrectable CRC or ECC error on read
11h data ECC corrected (hard disk)
20h controller failure
31h no media in drive (IBM/MS INT 13 extensions)
32h incorrect drive type stored in CMOS (Compaq)
40h seek failed
80h timeout (not ready)
AAh drive not ready (hard disk)
B0h volume not locked in drive (INT 13 extensions)
B1h volume locked in drive (INT 13 extensions)
B2h volume not removable (INT 13 extensions)
B3h volume in use (INT 13 extensions)
B4h lock count exceeded (INT 13 extensions)
B5h valid eject request failed (INT 13 extensions)
B6h volume present but read protected (INT 13 extensions)
BBh undefined error (hard disk)
CCh write fault (hard disk)
E0h status register error (hard disk)
FFh sense operation failed (hard disk)
您也没有指定DS:SI
要接收信息的设置。是否已正确设置?
从您的评论中:
01h AH 中的功能无效或参数无效。
检查 INT13 扩展是否可用于您的 BIOS。AH = 41h,DL = 80h(第一个驱动器),BX = 55AAh,INT13,如果有扩展,进位将在返回时清除。
有些计算机没有正确保存您的 ds 和 es 寄存器,因此这些应该在从 int-13 function-48 返回时恢复,还检查缓冲区大小为 1A 1E 或 42,具体取决于版本。
