BIOS
Auf dem Board steht als gewünschter Bios Chip ein 27C256 der Chip selbst ist ein M27C512 von ST.
Maintenance
- Erster Funktionstest – OK
- Verschmutzung – Kaum nur mit einem Pinsel abgebürstet
- Batterie – War entfernt, kaum Schaden, habe ich durch ein CR2032 ersetzt siehe unten.
- Schäden – Verbogene Pins gerade gerückt sonst nichts
- Jumper – Waren ok.
- Slotblech für On-Board Anschlüsse rausgesucht und getestet.

Problems
General cross-computer issues
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
General cross-computer optimisation
- 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)

Miscellaneous
Batterie durch CR2032 ersetzt
Hierzu habe ich den Ladeschaltkreis am Widerstand unterbrochen (siehe Bild) und einfach eine Halterung für eine CR2032 an die alten Kontakte für die Batterie gelötet.
