Intel® Server System S7000FC4UR TPS BIOS Initialization
Revision 1.0
147
The BIOS supports Universal Serial Bus Revision 2.0 Specification mode of operation, and as
such supports Universal Serial Bus Revision 1.1 Specification and Universal Serial Bus
Revision 2.0 Specification compliant devices and host controllers.
During the pre-boot phase, the BIOS automatically supports the hot addition and hot removal of
USB devices and a short beep is emitted to indicate such. For example, if a USB device is hot
plugged, the BIOS detects the device insertion, initializes the device, and makes it available to
the user. During POST, when the USB Controller is initialized, a short beep is emitted for each
attached USB device (includes front panel hub).
Only on-board USB controllers are initialized by BIOS. This does not prevent the operating
system from supporting any available USB controllers, including on add-in cards.
14.3.7.2 Legacy USB Support
The BIOS supports PS/2 emulation of USB keyboards and mice. During POST, the 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.
14.3.8 Serial ATA (SATA) Support
The BIOS supports and initializes SATA IDE devices only. Hot plugging SATA drives during the
boot process is not supported by the BIOS and may result in undefined behavior.
14.3.9 Removable Media Drives
The BIOS supports removable media devices in accordance with the Tested Hardware and
Operating System List.
The server system supports and initialize an ATAPI CD-ROM / DVD ROM optical drive through
an on-board SATA to PATA converter. From the BIOS standpoint, the CD-ROM / DVD-ROM
drive looks like a SATA drive and BIOS treats it as SATA device.
In addition, the BIOS supports USB mass storage devices such as CD-ROM / DVD-ROM drive,
floppy drive, and USB flash drive devices. The BIOS supports booting from these removable
devices.
The BIOS supports the Universal Serial Bus Revision 2.0 Specification compliant media storage
devices that are backward compatible to the Universal Serial Bus Revision 1.1 Specification.
The BIOS does not support ISA floppy drives.
14.3.10 Flash ROM
The BIOS supports the Intel
®
Advanced+ Boot Block Flash Memory 28F320C3B part of size
4MB. There are two such flash parts providing a combined flash size of 8MB. This capacity is
used to store two BIOS images as required to support the Rolling BIOS feature. Each BIOS
image contains:
System initialization routines
BIOS Setup utility
