MOV DX,0080

The hard disk light will come on and it will go through the low level format. When finished, it will print out three lines of test figures. The figures should include AX = 0000. If AX = 0000 then follow these instructions:
Reboot (ALT-CTRL-DEL)
FDISK
FORMAT C:\S

If AX not = 0000, then there is a problem with the hard drive, and the computer should be taken to a procare centre for servicing.
