Flashing BIOS on a Toshiba C875D

It seems that Toshiba is largely abandoning customer self-support for its laptops. I have a C875D-S7331 that is not registering any audio device. I suspect it was subject to a power surge, and would like to flash the bios. I've already tried driver updates.

The Toshiba site shows version 6.10 for the bios. The other versions it lists are errors; they have nothing to do with this machine.

The problem is that the flash utility will not re-flash the same version the machine already has. So I cannot flash the bios. I thought to try an older version, but couldn't find one. I tried newer versions than 6.10, but they were not for this particular model.

So I decided to ask at the Toshiba support forums - and found there aren't any. They have helpful KBs and videos, and they point you to the MS forums and to Tom's Hardware. And there is telephone support, which I assume costs money.

I also tried flashing from a CD, but it too would not reflash the same version.

So I'm looking for any insight on how to get this machine flashed, short of waiting for a newer version to possibly come out. And here's a little heads-up about the state of Toshiba support.
 
with Dell you would run the following type command
BOISName.exe -Force
 
Thanks, KYHI, that's a great idea. For some reason, though, both the executables in the bios download require windows. I tried them by booting to FreeDOS. That doesn't make sense, unless the CD burn of the BIOS is a WinPE, and I don't think it is; certainly not with graphics.

Ok, I got it. I found the routine here. After the flash program expands itself into a directory, there's a platform.ini file that has a BIOS_Version_Check section. Set flag=0, and then flash away.
