I have bought this 486 PCI motherboard
http://www.amoretro.de/2012/09/qdi-mp4-p4u885 … otherboard.html
It was still sealed, NOS condition.
I think this motherboard is little strange compared to others 486 PCI mobo, because it has only an IDE controller integrated, instead of a complete I/O interface.
Anyway, my issue is that I cannot understand why the system normally boots the DOS 6.22, but not any Win9x versions.
What I do is the following:
- Install DOS 6.22
- Enable optical drive using Mscdex
- Start installation of Win95 or Win98
The installation works well without any issue, but at the first reboot the system says "Disco di non di avvio" ("No bootable device" in English). Note the message is in Italian, this means that some access at the data occurs.
If I try to put that HDD in any other PC, it boots normally.
If I put a Promise Fasttrack PCI IDE controller in 486 motherboard, it boots normally too!
I tried to connect at 486 integrated controller the HDD of another PC, with Win95 installed, same issue, no boot.
Essentially, the IDE integrated controller does not boot any Win9x.
I do not want to solve the problem by simply leaving the Promise PCI controller installed, because this cause another issue with EMM386, like you can read here Emm386.exe won't load with an IDE controller card in the computer.
Can someone help me?
