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.
7.
Additional USB legacy feature options can be access by using Intel
®
Integrator Toolkit.
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.
3.5
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 USB
drive (a flash drive or a USB hard drive), or a CD-ROM, or from the file location on the Web.
•
Intel
®
Flash Memory Update Utility, which requires booting from DOS. Using this utility, the
BIOS can be updated from a file on a hard disk, a USB drive (a flash drive or a USB hard drive),
or a CD-ROM.
•
Intel
F7 switch during POST allows a user to select where the BIOS .bio file is located and
perform the update from that location/device. Similar to performing a BIOS Recovery without
removing the BIOS configuration jumper.
•
Intel Visual BIOS allows the user to select the BIOS .bio file from the internet, USB device, hard
disk drive, or other media.
All utilities verify that the updated BIOS matches the target system to prevent accidentally
installing an incompatible BIOS.
