Legacy USB Support

Legacy USB support enables USB devices to be used even when the operating system's
USB drivers are not yet available. Legacy USB support is used to access the BIOS
Setup program, and to install an operating system that supports USB. By default,
Legacy USB support is set to Enabled.
Legacy USB support operates as follows:
1. When you apply power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to
enter and configure the BIOS Setup program and the maintenance menu.
4. POST completes.
5. The operating system loads. While the operating system is loading, USB keyboards
and mice are recognized and may be used to configure the operating system.
(Keyboards and mice are not recognized during this period if Legacy USB support
was set to Disabled in the BIOS Setup program.)
6. After the operating system loads the USB drivers, all legacy and non-legacy USB
devices are recognized by the operating system, and Legacy USB support from the
BIOS is no longer used.
To install an operating system that supports USB, verify that Legacy USB support in
the BIOS Setup program is set to Enabled and follow the operating system's installation
instructions.

BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on
the Intel World Wide Web site:
®
• Intel Express BIOS Update utility, which enables automated updating while in the
Windows environment. Using this utility, the BIOS can be updated from a file on a
hard disk, a 1.44 MB diskette, or a CD-ROM, or from the file location on the Web.
®
• Intel Flash Memory Update Utility, which requires creation of a boot diskette and
manual rebooting of the system. Using this utility, the BIOS can be updated from a
file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette drive)
or a CD-ROM.
Both utilities verify that the updated BIOS matches the target system to prevent
accidentally installing an incompatible BIOS.
NOTE
Review the instructions distributed with the upgrade utility before attempting a BIOS
update.
