Ok, this thing is driving me mad ...
After a long pause (moving into a new appartment, working on the P133 and the Athlon 700), I decided to get back to that 486.
It just doesn't want to work.
Currently, it will run several programs with no pb (himem, my packet driver, all from mtcp, all basic msdos commands) but won't run anything like pkunzip, speedsys or chkcpu without hanging/showing a message from EMM386 saying an error has been detected at some adress.
Here's what I tried, the only common denominators being the HOT419 DZ/R2 and the 5GB HDD :
- DX4 100 WB
- DX4 100 WT
- DX2 66 WT
(with correct, as far as i can tell, jumper hell settings)
- DC680-T caching ctrl (cache on/off)
- windbond stupid ctrl
- 64MB FPM
- 32MB FPM
- 16MB FPM
- 2 different VLB ET4000/W32p
- ISA cirrus logic 5429
- BIOS on fail safe
- BIOS on performance
- BIOS manually tuned
- any mix of the previous choices.
I just can't run chkcpu 🙁
Can a faulty HDD give that kind of problems ?
