Nun habe ich auch einen 386DX40 auf einem MSI Mainboard. Das Mainboard hatte einen Batterieschaden und wenn ich mir das abgeknipste Beinpaar ansehe, wohl einen kurzgeschlossenen Tantal Kondensator. Der Schaden an der Dinbuchse für die Tastatur wurde mit zwei Kabelbrücken bereits behoben, das Board funktioniert einwandfrei. Was mich einlädt, mal ein paar Tests zu machen.

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 Passwort bei AMI Bios ist -> ami

Conclusion
| Question | Antwort |
|---|---|
| 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€ for the board |
| Was the price okay? | mehr als OK |
| Is it worth it? | Für Software 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 |
