1. Basic System Board Hacks > 6. Configure Boot Device Order

Configure Boot Device Order

Don’t wait for the floppy disk or CD-ROM to time out before the system boots.

One advantage of modern BIOS and hardware capabilities is that they allow you to boot up from something other than a diskette or hard drive. BIOS can now fetch and run an operating system from an appropriately capable and configured LAN adapter or a bootable CD-ROM. You can tell the BIOS which devices it should try to boot up from, and in what order.

For a faster boot time you probably want your hard drive to be the first device in the list, as shown in Figure 1-8, ignoring the presence of diskettes or bootable CD-ROMs, although some BIOSes will detect the presence of a bootable CD-ROM and offer the option of booting off the CD regardless of the boot device order you set. Skipping the process of looking for a bootable diskette or CD-ROM by telling the BIOS to boot from the IDE hard drive first can shave anywhere from a few seconds to tens of seconds off your boot time.
