<Ctrl><Alt><\>. (For keyboards that do not use American English, press <Ctrl><Alt><#>.)
l Bus Speed — Speed of the microprocessor's system bus
l Processor ID — Manufacturer's identification code(s) for the installed microprocessor
l Clock Speed — Core speed at which the microprocessor(s) operates
l Cache Size — Size of the microprocessor's L2 cache
l Hyper-Threading — Enables or disables Hyper-Threading technology for operating systems that support this feature. The default
setting is Disabled.
Diskette Drive A — Type of floppy drive(s) installed in the computer. With the standard cabling configuration, Diskette Drive A (the boot
floppy drive) is the 3.5-inch floppy drive installed in the top externally accessible drive bay. The two options are 3.5 Inch, 1.44 MB, and Not

Fastboot
l On (default) — Your computer boots faster by skipping certain configurations and tests.
l Off — Your computer does not skip certain configurations and tests during the boot process.
Integrated Devices — Configures the following devices integrated with the system board:
l Sound — Settings are On (default) or Off.
l USB Controller — Settings are On or Off.
l Network Interface Controller — Settings are On (default), Off, or On w/ PXE.
l Mouse Port — Settings are On or Off.
l Serial Port 1 and Serial Port 2 — Settings are Off and Auto (default).
Auto automatically configures a connector to a particular designation (COM1 or COM3 for Serial Port 1; COM2 or COM4 for Serial
Port 2).
If you set a serial connector to Auto and add a card containing a connector configured to the same designation, the computer
automatically remaps the integrated port to the next available connector designation that shares the same IRQ setting as follows:
¡ COM1 (I/O address 3F8h), which shares IRQ4 with COM3, is remapped to COM3 (I/O address 3E8h).
¡ COM2 (I/O address 2F8h), which shares IRQ3 with COM4, is remapped to COM4 (I/O address 2E8h).
