Updating Your BIOS
PHLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the
programmable flash ROM on the Notebook PC’s motherboard. This file works only in DOS mode. To
determine the BIOS version, check the code (e.g. BIOS Ver. XXXXX) displayed on the upper left-hand
corner of your screen just before entering BIOS setup (after pressing the F2 key). Larger numbers represent
a newer BIOS version.
Creating a BIOS Update Floppy Disk
PHLASH works only in DOS mode. It will not work with DOS prompt in Windows and will not work with
certain memory drivers that may be loaded when you boot from your hard drive. It is recommended that you
reboot using a floppy disk.
1. Download an updated BIOS file from the Internet (WWW or FTP) (see Contact Information).
2. Type FORMAT A:/S at the DOS prompt to create a bootable floppy disk. DO NOT copy
AUTOEXEC.BAT & CONFIG.SYS to the floppy disk.
3. Copy PHLASH.EXE, PLATFORM.BIN, and the original BIOS (from the support CD) and new
BIOS (from the Internet) files to the just created bootable floppy disk.

PLATFORM.BIN, and BIOS files to your hard disk drive from the support CD or the Internet. When
possible, ask your dealer where you can find the latest BIOS file on the Internet.
