							Updating the BIOS
Updated versions of the BIOS may be available on the HP website.
Most BIOS updates on the HP website are packaged in compressed files called 
SoftPaqs.
Some download packages contain a file named Readme.txt, which contains information regarding
installing and troubleshooting the file.
Determining the BIOS version
To determine whether available BIOS updates contain later BIOS versions than those currently
installed on the computer, you need to know the version of the system BIOS currently installed.
BIOS version information (also known as 
ROM date and System BIOS) can be revealed by pressing
fn+esc (if you are already in Windows) or by using Computer Setup.

Using MultiBoot
About the boot device order
As the computer starts, the system attempts to boot from enabled devices. The MultiBoot utility,
which is enabled at the factory, controls the order in which the system selects a boot device. Boot
devices can include optical drives, diskette drives, a network interface card (NIC), hard drives, and
USB devices. Boot devices contain bootable media or files that the computer needs to start and
operate properly.
NOTE:Some boot devices must be enabled in Computer Setup before they can be included in the
boot order.
You can change the order in which the computer searches for a boot device by changing the boot
order in Computer Setup. You can also press esc while the “Press the ESC key for Startup Menu”
message is displayed at the bottom of the screen, and then press f9. Pressing f9 displays a menu
that shows the current boot devices and allows you to select a boot device. Or, you can use MultiBoot
Express to set the computer to prompt you for a boot location each time the computer turns on or
restarts.
Choosing MultiBoot preferences
You can use MultiBoot in the following ways:
●To set a new boot order that the computer uses each time it is turned on, by changing the boot
order in Computer Setup.
●To dynamically choose the boot device, by pressing esc while the “Press the ESC key for
Startup Menu” message is displayed at the bottom of the screen, and then pressing f9 to enter
the Boot Device Options menu.
●To use MultiBoot Express to set variable boot orders. This feature prompts you for a boot device
each time the computer is turned on or restarted.
Setting a new boot order in Computer Setup
