There is a BIOS update available for my MB. I have flashed the BIOS on other computers in the past but not recently enough to know whether I can expect FSX or other software activation to be clobbered, or if any other license issues might crop up and require re-installation. I'd just like to get a feel for the amount of aggravation that might result from an operation with, as yet, unknown benefits (no release notes available). I suppose I could always wait until I have to re-install the OS and do the BIOS update before re-installing other stuff. Any thoughts?Rick

There won't be any problems with software activation, but there is a small chance you could get other issues like your system failing to boot, or stuff like that. Generally, I think, BIOSes are updated to fix bugs, to make them (and therefore the whole computer) run faster, or to include support for more hardware. Personally, I give it a good couple of months after a new BIOS has been released and check forums etc. for any issues they might cause before updating, so as to hopefully let any common problems pass me by.
