BIOS Version
BIOS Version displays the version number and release date of the basic input/output system (BIOS) in your computer. A service technician may
ask you for this version number if you call Dell for technical assistance.
Boot First Device
Boot First device determines which disk device your computer uses to find the software needed to start the operating system.
The term boot refers to the computer's start-up procedure. When you turn on the computer, it "bootstraps" itself into an operational state by loading
into memory a small program, which in turn loads the necessary operating system. Boot First device tells the computer where to look first for the
files that it needs to load.
Settings for this option are:
l Diskette Drive (the default) — Causes your computer to attempt first to boot from a bootable diskette
l Internal HDD — Causes your computer to attempt first to boot from the hard-disk drive
l CD-ROM/DVD-ROM Drive — Causes your computer to attempt first to boot from a bootable CD
l Ext Media Bay HDD — Causes your computer to attempt first to boot from the second hard-disk drive installed in the external media bay
l PCI Slot NIC — Causes your computer to attempt first to boot from a network interface controller (NIC) PC Card
NOTE: Dell may periodically offer revisions of the BIOS that add features or solve specific problems. Because the BIOS for your
computer is stored on a reprogrammable flash-memory chip, you can use the Flash BIOS Update program to update your computer's
BIOS entirely through software.
