So updating a BIOS from an earlier socket that the CPU is using, to a new socket is not recommended for long term use?
Um, how did you come to that conclusion from that post?
You're not updating the socket, you're updating the list of supported CPU's
You flash the BIOS first. If the old BIOS does not support the new CPU your PC may not post. If it doesn't post, you can't flash the BIOS. The new BIOS file just adds more CPU support, it will still support the old CPU.
The BIOS looks for code on the CPU that tells it what clock multiplier and voltage to use. CPU's made after the motherboard is manufactured may not be in the list. If the motherboard can't figure out what settings to use it doesn't boot up to prevent damage. You'll get a not supported message or just a flashing cursor. In that case the manufacturer adds them to the BIOS code. Then to get the new support you flash your BIOS. Just be sure the BIOS file you plan to use is meant for your motherboard. If its not you could damage your motherboard.
