Problems

Generelle Computer übergreifende Probleme

Computer

Doesn't start, no postcodes

• Check frequency
• Check multiplier
• Check the voltage
• (Pentium) Possibly change setting for Pentium and Pentium MMX (Dual Voltage).

Freezes / Computer crashes during Doom test

• Test memory
• Check memory. Possibly remove/exchange modules and test with a different configuration.
• Check BIOS settings (possibly set too quickly)
• Check board settings such as voltage and frequency.

Crashes after memory dive

• Test memory in device or another computer.
• Check if the board supports the memory and size
• Possibly install BIOS update

CPU

Fan bracket defective

• There are two other hooks where the heatsink could be attached with wire.
• Sticking it onto the processor would also be a possibility, or using a processor with a pre-applied cooler.
• Furthermore, there are coolers that can simply be clipped onto the CPU.

Hard drive

Not recognised

• Manually enter hard drive parameters.
• Test setup with a different hard drive.
• Test hard drive in another device.
• BIOS Update (possibly hard drive too new)
• Try the XT-Ide BIOS.#

BIOS

General Problem

• Clear BIOS settings reset.
• Update BIOS.
• If no newer BIOS is available, you can also look for successor models with the same chipset. For example, a 486 BIOS can also work on a 386.

New BIOS requires password

• Remove battery to clear settings
• Password reset jumper set
• Standard password for AMI BIOS is -> ami

Miscellaneous

Conclusion

Für Spiele und Anwendungen der 286 – 486er Ära bis hin zu den Spielen um ca. 1996 ist er ausreichend. Spiele wie Doom I/II, Quake, und Duke Nukem 3D lassen sich mit dem P133 spielen aber mehr spass macht mit dem rund 33% schnelleren P200 MMX. Aktuelle ist der Prozesse zwichen 1€ und 16€ zu haben.
