can i simply

bios update a K8N SLI platinum edition, swap a 3200+ for a X2 4400+ and just turn back on to bask in the delights of dual core?
 
Yes. Windows will dynamically update the HAL on the first boot to a multiprocessor HAL from the original uni-processor HAL. Of course you?ll have to make sure that you have the correct BIOS rev beforehand.

You can do it manually if need be, but this shouldn?t be necessary if you doing things properly in the first instance (aka maing sure you have a dual core compatible BIOS).
 
As an aside, I completely upgraded my computer last week. Moved my existing OS install on its hard drive (one of only three components to move....the hd, video card, and an optical drive were the three components to make the move) and fired it up.

What it was......Asus nForce 4 A8N-SLI Deluxe motherboard with 2 x 1GB Corsair XMS PC3200 RAM, Athlon 64 4000+ cpu.

What it became.....Intel 975BX2 motherboard with 2 x 1GB Buffalo Firestix DDR2-800 RAM, Intel e6600 cpu.

The move went flawlessly. Fired right up, not a single problem. On initial boot, couldn't find the proper chipset drivers, obviously, but still ran and ran well. Installed the 975 chipset driver CD and off it went.

Did have to reactivate, but it'd been a while since it last had to be activated, so did it over the 'net without a hitch.

Using this same sequence on moving from various nForce chipset motherboards was always much more drama.

In your case, just dropping in a dual-core cpu in place of a single core should be cake!

Unfortunately this didn't work for me. I had the proper BIOS, etc, but windows xp pro sp2 didn't detect the processor switch completely (showed 2 cores in device manager but only a single core in task manager and I did have the view set to show each cpu seperately). I had to do a reinstall of the OS to correct, ymmv. Theoretically it should've worked without issue, but unfortunately it did not for me.

So, you didn't try going to hardware manager and updating the CPU driver ?
