Prioris XL and XLDP 5166
CPU Powergrade Kit
Introduction
Thank you for purchasing the Prioris™XL or XLDP Powergrade Kit. These
Powergrade kits contain all the components and instructions required to upgrade
your server to a Pentium®CPU with a speed of either 166 MHz or 200 MHz:
Model Prioris™XL
5166 Prioris™XL 5166DP Prioris™XL 5200 Prioris™XL 5200DP
CPU 1- 166 MHz 2- 166 MHz 1- 200 MHz 2- 200 MHz
Installing this Powergrade kit involves updating your system BIOS (Basic Input-
Output System). To do this, you will need to remove any video option card, if
installed, and enable the internal VGA controller. Once the BIOS process has
completed successfully, you can then reinstall any video option card. You must
install the new BIOS before installing your Powergrade kit. This installation
guide provides the necessary details.
Tools Needed
• Phillips screwdriver, 1 pt.
• Antistatic wrist strap with grounding clip (provided)

* These kits are used when a Main Logic Board (54-23456) does not meet upgrade specifications; in which
case, a new MLB (54-23984-01) is included in the kit, which requires Digital MCS installation.
Enable the Onboard VGA Controller
Before updating the BIOS, you must remove any video option card and enable the
onboard VGA.
1. Insert the SCU diskette into drive A and turn on or reset your server. The
diskette should boot automatically.
2. When the SCU title appears, press any key to continue. Afterwards,
follow the instructions on your screen to access the SCU main menu.
3. From the main menu, use the arrow keys to highlight an item and then
press Enter to select it. Press F1 at any time for help about a selection.

4. Select the Advanced Control Group and enable the
Embedded - PCI VGA controller.
5. Select Save and Exit to save this selection.
Update Your BIOS
A diskette containing the required BIOS (Basic Input-Output System) software is
included with the Powergrade kit. BIOS is software that is in a nonvolatile read-
only memory (ROM) chip, which is on the main logic board of your computer.
The BIOS has several functions, including initializing hardware and booting the
operating system when the computer is turned on.
You must install the new BIOS before installing your Powergrade kit.
Power Down the Server
1. Turn off your server.
2. Disconnect any external devices, the ac power cord, and the monitor
power cord.
3. Unlock the front security lock on the server.
4. Remove the left side panel by sliding it toward the rear of the server.
WARNING: You might injure yourself or damage your server if you
attempt to remove the side panel before unplugging the ac and monitor
power cords.
Remove any Video Option Cards
Before updating the BIOS, you must remove any video option card and use the
embedded PCI VGA controller.

removed.
2. Connect the cables, the monitor power cord, and the server power cord to
the back of the server.
Power Up the Server and Update Your BIOS
1. Turn on your server and allow the POST to complete. Your computer
automatically boots from the BIOS Upgrade diskette in Drive A.
2. At the MS-DOS prompt, change the directory to upgrade.
Example:
A:\cd upgrade
3. At the MS-DOS prompt, type: upgrade
NOTE: You must have an MS-DOS formatted diskette for the
current BIOS and for the upgrade BIOS.
4. At the menu, select "Make Recovery Diskette From Flash."
5. At the menu, select "Flash BIOS from IMAGE File." Press Continue and
select the following:
V208_EN.BIN
Program
The BIOS upgrade procedure will run automatically.
NOTE: DO NOT power down the system once this procedure has
started. If the system loses power, or if at the end of this procedure
the system fails, please refer to the section, "Troubleshooting – Using
the Crisis Recovery Diskette if Necessary."
The system will reboot at the termination of the upgrade procedure.
6. Remove the diskette from Drive A.

Reset Jumpers on the Main Logic Board
1. As described previously, power down the server.
2. Make sure that the following jumpers, shown in Figure 1, are set to disabled
to prevent any unauthorized update to your BIOS:
J41 BIOS upgrade Disabled (Off)
J50 Boot block update Move the jumper back to the default position
shown in Figure 1 (pin 1 to pin 2).
Powergrade Installation
Remove the CPU Module
1. Place the antistatic wrist strap on your wrist and connect the grounding
clip to a non-painted metal surface of the computer's chassis.
2. Using a Phillips screwdriver, unscrew and remove the CPU module
retaining bracket (Figure 2).
3. Grasping both ends of the CPU module, carefully remove it from the main
logic board and place it on an antistatic surface.

Install a Second CPU Chip (FR-PC97U-AA, -AF Kits Only)
The CPU module has either one or two Intel®Pentium CPUs mounted with heat
sinks in socket 5 type ZIF sockets. If you are upgrading the existing CPU module
from a single processor to a dual processor (kit FR-PC97U-AA or -AF), install
the new Pentium Processor chip as follows:
1. Unlatch and lift up on the release lever.
2. Install the CPU chip (Figure 3). The arrangement of the pins is keyed for
correct placement. The chip also has a beveled corner (A), which may be
different on your board.
3. Return the release lever to its original position.

Install the Secondary Cache
Move the secondary cache (if present) on the old CPU module to the new CPU
module (Kits FR-PC97U-AB, -AG, and -AJ only). Kits FR-PC97U-AA, -AC,
-AD, -AE, -AF, and -AH have a new 512 KB cache module. Seat the cache
firmly into the socket (Figure 4).

Check the Jumper Settings
Figure 5 shows the CPU module’s jumper locations. The jumper settings for the
bus speed should be 66 MHz. Move the jumpers so they are set correctly for the
correct speed of the CPU you are installing.

1. Install the left side panel and lock the server.
NOTE: The server will not power up with the side panel
removed.
2. Connect the cables, the monitor power cord, and the server power cord to
the back of the server.
Run the System Configuration Utility (SCU)
The SCU enables you to check or change your server’s configuration. Run
the SCU to configure your server for the new CPU chip or module.
To start and run the SCU:
1. Insert the SCU diskette into drive A and turn on your server. The diskette
should boot automatically from the diskette.
2. When the SCU title appears, press any key to continue. Afterwards,
follow the instructions on your screen to access the SCU main menu.
3. From the main menu, press the up or down arrow to highlight an item and
then press Enter to select it. Press F1 at any time for help about a
selection.
4. From the main menu select Configure Computer and then View
and Edit Details. Example:
If you installed a video option card, select the Advanced Control
Group and disable the Embedded - PCI VGA controller.

4. Select Save and Exit to configure your server for the CPU module.
5. When complete, remove the SCU diskette from drive A and reboot your
server.
Refer to Chapter 3, “Server Utilities,” in your computer user's guide for any
additional information on running the SCU.
Troubleshooting
Using the Crisis Recovery Diskette if Necessary
The Crisis Recovery diskette may be used only if your computer’s BIOS fails or if
a BIOS upgrade is unsuccessful.
When using the Crisis Recovery diskette, you must remove any video option card
and enable the onboard VGA.
1. Turn off the server and make sure that the Onboard VGA jumper (J17, Figure
1) is installed (enabled).
2. Install a jumper on J39 (Figure 1) to set it to Recovery mode.
3. Insert the Crisis Recovery diskette into drive A and reboot the computer.
NOTE: Remember to remove jumper J39 to return it to
Normal mode after using the Crisis Recovery diskette.
