If an AdvancedMC module is installed before power up and recognized by the EFI BIOS,
then the resources required for that AdvancedMC module is determined and that
information is available to the operating system upon boot.
AdvancedMC modules shall only be installed before board payload powers on or after
the operating system has fully loaded. If an AdvancedMC module is hot added after the
initial EFI BIOS device discovery, but before the operating system is fully loaded, then
the AdvancedMC module may not work properly. To correct this, a board payload reset
or payload power cycle is required.
USB Support
Native USB Support
During the power-on self-test (POST), the EFI BIOS initializes and configures the USB
subsystem in accordance with chapter 14 of the Extensible Firmware Interface
Reference Specification, Version 1.1. The EFI BIOS is capable of initializing and using
the following types of USB devices:
USB devices are scanned to determine if they are required for booting.
The EFI BIOS supports USB 1.1-compliant devices and host controllers. The EFI BIOS
configures the USB 2.0-compliant host controller and USB 2.0-compliant devices in
USB 1.1 mode because all USB 2.0 devices are required to support USB 1.1 mode.
Although USB 1.1 mode is slower than USB 2.0 mode, the difference in speed is not
significant during the pre-boot phase. The operating system can reconfigure the USB
devices in USB 2.0 mode as required. The EFI BIOS configures the USB 2.0 host
controller (EHCI) so the operating system can use it.
During the pre-boot phase, the EFI BIOS automatically supports the hot addition and
hot removal of USB devices. For example, if a USB device is hot plugged, the EFI BIOS
detects the device insertion, initializes the device, and makes it available to the user.
Only onboard USB controllers are initialized by EFI BIOS. This does not prevent the
operating system from supporting any available USB controllers, including add-in
cards.
Legacy USB Support
The EFI BIOS supports PS/2 emulation of USB keyboards and mice. During POST, the
EFI BIOS initializes and configures the root hub ports and then searches for a keyboard
and/or a mouse on the USB hub and then enables them.
