No VT82C686x Southbridge Detected

Appreciate some assistance.

Changed from a troubled AMD CPU mainboard to a Pentium CPU mainboard. Everything else remained the same (W98SE, HDD, Modem, etc...) and so far appears to work fine, except for this problem.

Removed whatever (I thought) pertained to the AMD mainboard in Device Manager/System Devices.

Installed the mainboard with the Pentium CPU, and when the Desktop finishes, a prompt appears every time with the following info:
"Terminating: No VT82C686x Southbridge detected....etc. "

The VT82C686x chipset belonged to the mainboard with the AMD CPU. This mainboard was replaced.

The mainboard installed now has VT82C693A PCI/AGP Controller (PAC), and a VT82C596B PCI/ISA/IDE Controller chipset.

Any ideas of what to do to get this prompt to fly south?

Thank you for the help.

 

You need to reinstall your operating system from scratch. And by that I mean a fresh install not a reinstall. But since it only takes a 1/2 hour you could try a reinstall first. Swapping mobos without reinstalling your OS is just one of those things that people have learned about the hard way and don't mess with anymore.

 

Find myself complimenting Chiles4 for the second time this morning, everything he said is 100%. I would concur in a clean install to avoid a multitude of potential problems down the road.

Lazy mans approach may include an attempt to boot into safe mode and removing your Southbridge VT82C686x.

 

Update:

Changed mainboards from a troubled DFI AM75-TC (ViA Chipsets: VT8365A/686B) holding an AMD 1.1GHz CPU, to a Gigabyte-6VA7+ (ViA Chipsets: VT82C596/VT82C693A) holding a Pentium III 933MHz (Coppermine) CPU.

Quite a trip! Changed the mainboard and kept W98SE.

The hardware change was accomplished by deleting the HKEY_LOCAL_MACHINE\Enum Registry key and performing all sorts of reboots as the hardware was recognized.

Prior to doing "˜all of the above’, did a few items that were suggested, plus a little bit of research, and had no surprises:

1. Copied the contents of the win98 folder (with all the cab files) from the W98SE CD to the hard drive
2. Ran REGEDIT to access the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Setup registry key and changed the value of the SourcePath string to match the location of the win98 folder
3. Created a folder in C:\ and placed the 4 in 1 ViA drivers in it
4. Created a folder in C:\ and placed the AGP Graphics card drivers in it
5. Switched the Display driver to: Standard VGA

For a just in case, made a backup copy of Favorites and the email address book, but did not need them. In hindsight, did not make a copy of the registry, saving it to a CD. Perhaps that is an item to consider. Doing a scanreg /restore is also an option if there is serious trouble.

Had to reinstall the drivers for the modem and the sound card, as well as Dial-Up-Networking/Remote Access Service, Dial-Up-Adapter.

All went well, and the PC is up and running.

Thanks for all the help.
