I doubt it. I've yet to see a Linux flash utility. (Being tied to a
certain BIOS/MB combo, I doubt that we will ever see one)
Most flash utilities either use DOS (99%) or both Windows and DOS (~1%).
I was amazed to discover that Dell provide a linux flash utility for their 430SC baby server's BIOS. I've used it under CentOS 4 and it worked just fine.
