About to install a X2 4800 939 socket processor into a KN1 Extreme motherboard. Is it worth updating the bios before attempting this, or should I simply flash the bios after installing new processor? I've checked the latest bios update at the ECS website and it states "support Dual Core 3800" and the rather vague "Dual Core CPU Support" so I assume my new processor will be ok. But what's the likely scenarios I'm likely to encounter upon boot up after the new chip installation? Will the Mboard refuse to recognise new processor without bios flash, or will I just be able to update bios using WinFlash after boot-up? I'd rather not have to boot from A: drive with new bios on floppy as this sounds a bit tricky. Anyone got any advice whose been in a similar situation?

"I'd rather not have to boot from A: drive with new bios on floppy as this sounds a bit tricky" It is a bit tricky but IMO, it's safer than flashing from Windows. Check the CPU support list...it shows BIOS 1.2D: http://www.ecsusa.com/ECSWebSite/Su... "If my answers frighten you then you should cease asking scary questions" - Jules Winnfield (Samuel L. Jackson) in Pulp Fiction

If a BIOS update is necessary in order to properly configure a newer processor you are better off doing that while you are still using the original processor. Backup the original BIOS file to the floppy if that option is offered.
