Hi, I was successfully able to probe, read, erase, and write the Powerspec 8731 machine I have (temporarily anyway). I can't remember where the manufacturer BIOS updates are (not the same place as the drivers), so I just read the current BIOS, erased it, and then wrote it back successfully. If this isn't sufficient, please tell me and I'll track down an actual BIOS update instead.
The site for the machine is here: http://www.powerspec.com/systems/archives/system_archive.phtml?selection=873...
