Ok, so we finally decided to upgrade my wifes 486. I bought a used Intel Pentium 200mhz MMX system with 80mb ram and case.
I formatted and installed the two hard drives from the 486. Master is a Maxtor 540 and the slave is a Seagate 850 on the onboard pci primary ide controller. I added the floppy drive and a SB16 sound card for the CD Rom. Thats all I added to get started.
I got the drives installed and configured in BIOS, Installed Windows 95 w/usb support and all installed fine. From windows I can access both C and D drive as well as the CD Rom drive...no problem. However, whenever I try to access the floppy drive from Windows, the system comes to a screeching halt. Reset time! If, however, I use the MS-DOS prompt, I can access the A: drive with no problem. Even windows programs accessed this way will work and come back to windows and finish fine. It is when I access the A: drive using the RUN command, explorer or any other way from windows.
When I view the Device Manager from control panel, the floppy drive and floppy controller seems fine. No yellow flags. However, I do have a yellow flag on the:
Primary IDE Controller (dual fifo)
The secondary and the parent device - Intel 82371SB PCI Bus Master IDE Controller - show to be OK. When I view the properties of the failed Primary IDE Controller(dual fifo), it says that the device is not present, not working properly, or does not have all the driver installed. Also, in the performance tab of system properties, it shows that both hard drives are using MS-DOS compatibility mode file system. I checked every single entry in the device manager to see if any other device showed a conflict, none do.
I have tried reinstalling Windows four times. The same comes up each time. I can't understand why I am having this floppy drive lock-up and the yellow flag on the primary IDE. I'm sure they must be related, but it doesn't make sense since the hard drives seem to be operating OK. I also do not understand the MS-DOS compatibilty mode on the hard drives.
I also tried a fix that was supposed to correct a problem between Windows 95 and the Intel 82371SB PCI Bus Master IDE Controller. Apparantly Windows didn't have that device lised in the MSHDC.INF. I tried this fix and it didn't help. This problem was reported to cause CD Rom failures on the secondary ide, which isn't my problem, but tried it since it was the same hardware. In any event, this didn't help either. Tried formatting and installing again, back to ground zero...
Please...any help appreciated.
