System BIOS
4.2 Flash ROM
The Intel 82802AC Firmware Hub (FWH) includes an 8 megabit symmetrical flash memory
device. Internally, the device is grouped into eight 64-KB blocks that are individually erasable,
lockable, and unlockable.
4.2.1
Removable Media Support
The BIOS supports removable media devices, including 1.44MB floppy removable media
devices and optical devices such as a CD-ROM drive or DVD drive. The BIOS supports booting
from USB mass storage devices connected to the chassis USB port, such as a USB key device.
The BIOS supports USB 2.0 media storage devices that are backward compatible to the USB
1.1 specification.
4.2.2
Legacy USB
Legacy USB support enables USB devices such as keyboard, mice, and hubs 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 the user applies power to the server, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing the user 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 keyboard and
mice are recognized and may be used to configure the operating system. (Keyboard 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.
✏ ^NOTE
Legacy USB support is for keyboard, mice, and hubs only. Other USB devices are not
supported in legacy mode.
