Hello fellow vogons

I have a Octek RHINO 6VX socket 7 motherboard I've just put together

I was having issues with getting USB working in windows 95, so thought as part of the troubleshooting process I'd update the bios version to the latest, provided by the retroweb here:
https://theretroweb.com/motherboards/s/octek-rhino-6vx#bios

Everything seemed to go fine, but on reboot my floppy drive is no longer being detected, and Windows 95 has dropped a lot of things in device manager.. I've cleared the cmos to defaults and confirmed power to the drive is OK. If boot up floppy seek is enabled in the bios it reports an error when going through POST.

Outside of buying a new EEPROM and getting it flashed with the original bios (yes i backed it up), is there any suggestions on how to get my floppy drive working again?

Thanks

- Put the backup image on the HDD if it is not already there.
- Boot into Windows' real mode DOS
- Flash the original backed up BIOS back

Smashing idea! That got me back up and running. Thanks

Glad you got it working again.

As for why the other BIOS did not work well, I suspect that either your board is not the actually the same model/revision as the one you got a BIos for on Retroweb OR The BIOS you got on retroweb is misclassified and not actually for that board/rev.

If you ould you share a dump of your current working BIOS and the one you tried, maybe someone here could verify/analyze.

After double checking, my original POST string was "08/15/96-i430VX-2A59GO09C-00" and I updated to "02/27/97-i430VX-2A59GO0DC-00". Difference being "9C" and "DC" between the two bios POST strings.

I tried another bios version "12/02/96-i430VX-2A59GO09C-00" but found the system had the same issue and did not detect the floppy drive post update.

For anyone interested, the BIOS files I tried are from here:
https://theretroweb.com/motherboards/s/octek-rhino-6vx#bios

As far as I can tell, the board from that page is like for like what I have

Maybe one of these might work.

Turns out the bios files on the retroweb were labelled incorrectly, as the bios I needed was linked to another download...

I've managed to successfully update to the latest available bios for my motherboard revision. 😀

Please do let the maintainers know about any needed corrections if you have not done so already.

Glad you got a working BIOS updated system in the end.
