*****************************************************************************

During the upgrading of your computers BIOS, if the computer loses power or
fails to complete the process of upgrading the BIOS, the existing BIOS in
the computer may become damaged.  Lenovo HIGHLY recommends that the computer
is powered via the AC adapter during the entire BIOS update process.


Lenovo also recommends that you disconnect all peripheral devices from your
computer before you perform the BIOS update.  Peripheral devices include, but
are not limited to, docking devices (Desk Stations, port replicators), PCMCIA
and CardBus cards, USB and IEEE 1394 devices, printers, scanners, digital
cameras, etc.

It is not unusual to see a CMOS checksum error when you first reboot the computer
after installing the new BIOS.  
If you see this message on your screen, 
	Press the F9 key to load default configuration.
	Select Yes. 
	Press the F10 key to save default configuration and exit. 
	Select Yes. 

You won't see the CMOS checksum error again.

BIOS INSTALLATION INSTRUCTIONS
-------------------------------



---------------------------------------------------
 BOOT CD-ROM INSTALLATION METHOD
---------------------------------------------------
If your Lenovo PC is equipped with a bootable CD-ROM device (CD-ROM,
DVD-ROM, DVD-RW, DVD-Multi, etc.), and you have access to a CD writer
(burner, either installed in your Lenovo PC or in another PC), you can create
a bootable BIOS installation CD-ROM using this ISO CD image.

If you have CD burning software on your computer, chances are good it has set
itself up as the default handler for ISO CD-ROM images.  If this is the case,
the option to create the bootable CD-ROM from the BIOS Launcher, will launch
your CD burning software, ready to burn the ISO image to CD.  If your software
hasn't set itself up as the default handler for ISO images, we'll recognize
that fact, and let you know.

Once you create the bootable CD-ROM, simply boot your computer from the
resulting CD.  To boot from CD, you can either hold down the "F12" key while
you turn your computer on, or you can use Setup to change the boot priority
so the CD drive boots before the HDD.

Note, if your CD burner supports it, you can use a rewritable CD (CD-RW) disc
to create the bootable BIOS installation CD-ROM.  Be sure to erase the
rewritable disc (if it has data on it) before you proceed.  Once you are
finished updating your system's DMI values, you can erase and re-use the
rewritable disc.

IMPORTANT NOTE: Creating the bootable BIOS installation CD requires a specific
                set of steps that is unique to each CD authoring application.
                You cannot simply copy the ISO image to a blank CD and expect
                to be able to boot from it.
