Dear all,
I have one of these strange things we all love (or hate) retro HW for:
- I overclocked my 386sx25 to 33 mhz last week.
- no issues fast settings doing benchmarks from dos to win to win95. Stable as hell.
- I was then changing network cards to test an intel 100mbit.
- when I removed the card again the system didn’t boot anymore.
- I removed all cards, erased bios etc no success.
- I managed to get it back working by inserting a 60mhz oscillator again. No issues
- I just tried it again: slowest bios settings no cards etc: system won’t boot anymore with 66mhz oscillator
- I even ordered 5 new 66mhz oscillator but same result.
- room temperature is also the same 😀
- lower osci does work. Higher osci as 72mhz won’t work neither
Any ideas? The only thing I can imagine is the osci but all 6! defect?? Ok all from Ali. Anyway I am out of answers 😀
You have some?
Regards
