PC 360-S150 (Type 6598) - Pentium Pro 150/200 MHz Jumper Setting Procedures:
Processor/Bus-Speed/Clock-Ratio Jumper

Set these jumpers to match the processor installed.

Password Reset:
1. Power-off the computer.
2. Move the jumper from pins 14-15 to 13-14.
3. Power-on the computer. This erases both the power-on and administrator passwords.
4. Power-off the computer.
5. Move the jumper from pins 13-14 to 14-15.

CMOS Jumper:
1. Power-off the computer.
2. Move the jumper from pins 17-18 to 16-17.
3. Power-on the computer. This erases the CMOS information.
4. Power-off the computer.
5. Move the jumper from pins 16-17 to 17-18.

Configuration/Setup Utility Jumper:
This jumper setting enables and disables the Configuration/Setup Utility.

Flash Recovery Jumper:
If an interruption occurs during a Flash/BIOS upgrade, the BIOS might be left in an unusable state. This jumper enables you to restart the system and recover the BIOS.

1. Power-off the computer.
2. Move the jumper from pins 23-24 to 22-23.
3. Insert the upgrade diskette into the drive A.
4. Power-on the computer and listen to the speaker. You should hear beeps in the following sequence.
a. After the computer is powered-on, it beeps once. This beep marks the beginning of the POST.
b. After a short delay (less than 10 seconds), the computer beeps again. This marks the beginning of the recovery process. The recovery code is being copied into the flash component.
c. After about 30 seconds, the computer beeps twice, marking the end of the recovery process. Wait until the diskette drive in-use light goes out.
5. Power-off the computer and move the jumper from pins 22-23 to 23-24.
6. Leave the upgrade diskette in the diskette drive and power-on the computer.
7. Retry the original upgrade procedure.
