Dell Precision 350 User Manual page 21

Time is kept in a 24-hour format (hours:minutes). Change the start-up time by pressing the right- or left-arrow keys to increase or to
decrease the numbers or type numbers in both the date and time fields.
Disabled is the default.
This feature does not work if you turn off your computer using a power strip or surge protector.
CPU ID — Manufacturer's identification code for the installed microprocessor
CPU Information
CPU Speed — Processor speed at which the computer boots
l
Press the left- or right-arrow key to toggle the CPU Speed option between the resident microprocessor's rated speed (the default)
and a lower compatibility speed. A change to this option takes effect immediately (no restart is necessary).
To toggle between the rated processor speed and the compatibility speed while the computer is running in real mode, press
<Ctrl><Alt><\>. (For keyboards that do not use American English, press <Ctrl><Alt><#>.)
Bus Speed — Speed of the microprocessor's system bus
l
NOTE: The front side bus speed may appear as 133MHz, but due to Quad pumped architecture the effective speed is 533MHz.
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
l
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
Installed.
Tape drives are not reflected in the Diskette Drive A option. For example, if a single floppy drive and a tape drive are attached to the floppy
drive interface cable, set Diskette Drive A to 3.5 Inch, 1.44 MB.
Fastboot
On (default) — Your computer boots in 10 seconds or less, skipping certain configurations and tests
l
Off — Your computer does not skip certain configurations and tests during the boot process
l
Integrated Devices — Configures the following devices integrated with the system board:
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/ MBA. Settings for On w/ MBA are PXE, RPL, BootP, or
l
NetWare as the active boot mode.
Mouse Port — Settings are On or Off.
l
Serial Port 1 and Serial Port 2 — Settings are Off and Auto (default).
l
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).
NOTE: When two COM connectors share an IRQ setting, you can use either connector as necessary, but you may not be able to use them
both at the same time. If you are running the Microsoft Windows 95 or IBM® OS/2® operating system, you cannot use both serial
connectors at the same time. If the second connector (COM3 or COM4) is also in use, the integrated connector is turned off.
Parallel Port — The settings are Mode, I/O Address, and DMA Channel.
l
Mode settings are PS/2, EPP, ECP, AT, or Off. Set the Mode option according to the type of device connected to the parallel
connector. To determine the correct mode to use, see the documentation that came with the device.
I/O Address settings are 378h (default), 278h, or 3BCh. The settings are not available when Mode is set to Off.
NOTE: You cannot set the parallel connector to 3BCh if Mode is set to EPP.
DMA Channel appears only when Mode is set to ECP. Settings are DMA 1, DMA 3, or Off.
IDE Drive Interface — The settings are Off and Auto (default).
l
Auto turns off the IDE interface when necessary to accommodate a controller card installed in an expansion slot.
Diskette Interface — The settings are Auto (default), Read Only, and Off.
l
Auto turns off the integrated floppy drive controller when necessary to accommodate a controller card installed in an expansion slot.
Read Only prevents the computer's integrated floppy drive controller from writing to floppy drives and activates Auto.
