Every system must store the BIOS password information somewhere. If you are able to access the machine after it has been booted successfully, you may be able to view the BIOS password. You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.

You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0×370, and then reading the contents of port 0×371.
