Single/Dual Power Plane CPU Voltage Regulator Selections (JP1, 20)
The following jumpers set the voltage supplied to the CPU. Determine whether
your CPU has a Single Power Plane or Dual Power Planes and then the volt-
age that it uses. When a single power plane CPU is installed, the dual power
plane selections will be automatically disabled. When a dual power plane CPU
is installed, the single power plane selections will be automatically disabled.
You may have one jumper on the Single Power Plane and another on the Dual
Power Planes at the same time.
WARNING: Incorrect setting can damage your CPU. If you are not
exactly clear on CPU jumper settings, check with your retailer.

III. INSTALLATION
APIC Dual CPU Selection (JP14)
This jumper turns on or off the multiprocessor operating system’s support for multi-
processors regardless of the number of processors installed in the system.
For single processor operating systems (e.g. DOS, OS/2 Warp, Win3.1x,
Win95, Nextstep): You can use one (or two) processor(s) and this “APIC Dual
CPU Selection” jumper has no function (you may leave on default setting).
For multiprocessor operating systems (e.g. WinNT, Unixware, SCO Unix
MP, Solaris 2.51): You can use one or two processors and Enable this “APIC
Dual CPU Selection” jumper. This solution allows some multiprocessor operat-
ing systems to upgrade from one processor to two processors in the future with-
out having to reinstall a multiprocessor OS. Otherwise Disable the dual proces-
sor support in a multiprocessor operating system if for some reason necessary.

Dual CPU Compatibility
A table on the next page shows the compatible CPU’s to be used on the ZIF socket
for the second processor. The following are codes used in the table:
• Type 0: This type of CPU can be used as the first processor only. Almost all
CPU’s are in this category and therefore not listed in the table.
• Type 2: This type of CPU can only be used as the second processor.
• Type 0/2: This type of CPU can be used as the first or second processor.
• Core Speed: This is the advertised speed of the CPU.
• BUS Speed: This is the BUS frequency that the baseboard must be set to.
• S-Spec: This is the identification code marked on the surface of the processor
without an attached fan heatsink. The code is marked on the underside of pro-
cessors with an attached fan heatsink.

III. INSTALLATION
Power Connection Procedures
1. After all jumpers and connections are made, close the system case cover.
2. Make sure that all switches are in the off position as marked by
.
3. Connect the power supply cord into the power supply located on the back of
your system case as instructed by your system user's manual.
4. Connect the power cord into an power outlet that is equipped by a surge
protector.
5. You may then turn on your devices in the following order:
a. Your monitor
b. External SCSI devices (starting with the last device on the chain)
c. Your system power
6. The power LED on the front panel of the system case will light and the moni-
tor LED as well. The system will then run power-on tests. While the tests are
running, additional messages will appear on the screen. If you do not see
anything within 30 seconds from the time you turn on the power, the system
may have failed a power-on test. Recheck your jumper settings and connec-
tions or call your authorized dealer for assistance.
7. During power-on, hold down the <Delete> key to enter BIOS setup. Follow
the next section "BIOS SOFTWARE" for instructions.
BIOS Chip
The BIOS chip on the the Pentium CPU card and the Pentium Pro CPU card are
different. If purchasing a Baseboard with a CPU Card, the BIOS is correctly in-
stalled. If purchasing an additional card which uses a different processor, it should
come with a BIOS chip to replace the one installed on your Baseboad.
Support Software
FILELIST.TXT - View this file to see the files included in the support software.
PFLASH.EXE - This is the Flash Memory Writer utility that updates the BIOS by
uploading a new BIOS file to the programmable flash ROM chip on the mother-
board. To determine the BIOS version, check the last four numbers of the code
displayed on the upper left-hand corner of your screen during bootup.
NOTE: A binary BIOS file is no longer included with the support software.
Save the motherboard's BIOS file to a floppy diskette as soon as your system is
operational. See "Flash Memory Writer Utility" in this section to “Save Cur-
rent BIOS to File.”

IV. BIOS SOFTWARE
Flash Memory Writer Utility
1. Enable "Boot Block Programming" jumper as shown in section III.
2. Make sure the system is running in real mode. This utility will not operate if
the system is under protected mode or virtual mode. This means that you
cannot reprogram the motherboard BIOS under the Windows environment or
with any memory management software, including HIMEM.SYS. The fol-
lowing describes the easiest way run your system from real mode:
•
Boot from a floppy disk formatted with the "FORMAT A:/S" command with-
out creating CONFIG.SYS and AUTOEXEC.BAT files.
•
If you are using MS-DOS 6.x, you can bypass the AUTOEXEC.BAT and
CONFIG.SYS by pressing <F5> when "Starting MS-DOS . . . “ line is dis-
played on the screen.
•
For Windows 95 users, press <F8> to enter the Microsoft Windows 95 Startup
Menu and then choose "Safe mode command prompt only"
3. You should copy the contents of the \FLASH directory to your hard disk drive.
Once you have accomplished the above tasks, you can run the Flash Memory
Writer utility. To run the utility, change to the directory containing
PFLASH.EXE and then at the DOS prompt, type:
PFLASH <Enter>

IMPORTANT: Flash Type may also be "INTEL 28F001BXT." If "unknown"
is after "Flash type --," then this ROM chip is not programmable or not sup-
ported with the PnP BIOS and therefore cannot be programmed by the Flash
Memory Writer.
This screen provides three command options, which you can invoke by typing the
corresponding number of the command and pressing <Enter> key. The following
describes each command:

ASUS C-P55T2D User’s Manual
IV. BIOS SOFTWARE
1. Save Current BIOS to File (Perform as soon as system is running)
This option allows you to copy the contents of the Flash memory chip into a file in
the \FLASH directory. This gives you a backup copy of the original motherboard
BIOS in case you need to re-install it. In such cases where the data on the chip get
lost or corrupted, you can reprogram the chip using this backup copy.
2. Update BIOS Main Block from File
This option updates the BIOS from a file on the disk. This can either be a new file or
a backup file created by the “Save Current BIOS to File” option. This will not
update the Boot Block if the Boot Block is different. You will be prompted with the
following if advanced features if necessary.
Boot Block of New BIOS is different from old one !!!
Please Use 'Advanced Feature' to flash whole bios !!!
3. Advanced Features
Selecting this option brings up the Advanced Features screen for clearing the PnP
configuration record and updating the motherboard BIOS.
To terminate the program and return to the DOS prompt, press the <Esc> key. Se-
lecting the third option displays the Advanced Features screen.
Advanced Features
Flash Type -- SST 29EE010

1. Clear PNP ESCD Parameter Block
2. Update BIOS Including Boot Block and ESCD

IV. BIOS SOFTWARE
To select an option, type its corresponding number in the provided space and then
press the <Enter> key. Follow these procedure to update the PnPmotherboard BIOS.
1. Download the new BIOS by selecting the second command option from the
Advanced Features screen. The program displays a second screen prompting
you for the name of the BIOS file. Type in the complete name of the file,
including the file name extension, and then press the <Enter> key. The utility
then downloads the new BIOS file. The following message appears:
DO NOT TURN OFF THE SYSTEM IF THERE IS A PROBLEM!
If you encounter problems while downloading the new BIOS, DO NOT turn
off your system since this might prevent your system from
booting up. Just repeat the process, and if the problem still persists, download
the original BIOS file you saved to disk.
2. After successfully downloading the new BIOS file, exit the Flash Memory
Writer utility and then turn off your system. Set the jumper back to its de-
fault setting of Programming “Disabled.”
3. Turn on the system and hold down <DEL> to enter BIOS Setup. You must
load "Setup Default" to affect the new BIOS.
WARNING: If the Flash Memory Writer utility was not able to successfully
download a complete BIOS file, your system may not be able to boot up. If
this happens, your system will require service from your vendor.
