Ok it took alot of digging but I found the BIOS update for the Vision top MB BIOS String MVP3-W83-586B-2A5LEV5CC-00
You will need to Download the awdflash.exe file and put it on a floppy with the bin file. At the A promt type awdflash mvp30716.bin
And make sure you backup your old BIOS jus in case. It work for me without anyproblems.
Also here are the URLs
There was also a link to the P2-BX made by Vision Top, not sure if it works.
