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。
