Maintenance

• Erster Funktionstest – OK
• Gereinigt – War sauber
• Batterie entfernt – war schon weg
• Leiterbahnen repariert – war schon repariert
• Batterie durch Knopfzelle ersetzt – No Varta Hochkannt passt aber nicht gut

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

Generelle Computer übergreifende Optimierung

• BIOS – Update
• BIOS patcherBPA Award/Phoenix Version 4.23 (Ami a Version 6.00)
• ATX Power Supply Adapter (up to ATX)
• Install coprocessor (up to and including 386)
• XT-IDE ROM for Larger Hard Drives (Up to Pentium I)
• ISA Blaster for USB Mouse (as long as no PS2 or USB is present)
• DIN to PS2 adapter for keyboard (as long as no PS2 or USB is available)
• Compact Flash as HDD replacement (up to Pentium, then rather SSD due to speed)
• Gotek or FDD Emu as FDD replacement
• Pico GUZ as a sound card replacement (until May Pentium is 8-bit)
• PicoMem for memory, sound and HDD (Up to a maximum of 486, 8-bit)

Conclusion

Question	Answer
Does the board work	Ja aber wurde vom Verkäufer repariert.
How much did it cost?	121,50€ Ges. Preis – IM Gehäuse, mit Festplatte, 5.25″, 3,5″, Graphikkarte, CDRom => 30-60€ für das Board
Was the price okay?	mehr als OK
Is it worth it?	Für Sofware aus den 80ern ist er genau das Richtige. Wer mit Doom, Quake, Duke Nukem 3D spass haben will braucht etwas stärkeres zum Beispiel den 486 DX2 66 oder stärker.
Overall conclusion	Positive
