An apparatus and a method to prompt for an administrative password during the boot block process to flash a corrupted ROM image. During a computer system's power-up and initialization, the flash ROM image is examined to determine if the image is corrupt. If so, the computer system executes certain protected code stored in the boot block of the ROM. When the computer system is booted from this boot block, a reduced set of capabilities are needed. One capability according to the invention, is the ability to flash a new ROM image to the corrupted ROM. Once booted from the boot block, the computer system prompts the user for a password preferably by flashing keyboard LEDs. Upon receiving a password, this password is compared to an administrative password stored in non-volatile memory. If the password matches the administrative password, then the computer system enables the ROM to accept a flash ROM image. If the password does not match, the ROM is disenabled, not accepting a flash ROM image.
