PHLASH.EXE

All computers have BIOS software in a read-only, non-volatile memory (ROM) chip. This BIOS initializes
hardware and boots the operating system when the computer is turned on. The BIOS also provides access
to other services such as keyboard and disk drives.
The computer comes equipped with flash memory. This means the computer's BIOS can be restored
simply by running the PHLASH.EXE utility contained on the supplied System Utilities diskette. The
computer's BIOS can also be upgraded to future releases by running PHLASH.EXE along with any flash
BIOS update diskette if necessary.
