Here's what I copied from an AnandTech forum around 7/22/2000, but I know there are other threads too:

! How to swap motherboards & leave system intact.doc
7/22/00
Q What's the easiest way to change a motherboard and get Windows back up and running like I used to? I got win-dows on a partition by itself but I don't want to lose my file associations and shortcuts and what not. Could I just rein-stall windows without formatting my c: drive? Would Windows set itself up for the new motherboard automatically (in terms of the devices on the board, not sound cards etc...)? Thanks.
A You can try this, it has worked for me..go into device manager and delete all your devices that you have to add driv-ers for...then when it asks you to reboot click ok, but after it starts the reboot shut down your system...swapout mother-boards and I would just install the video card at that point. Boot to Bios, auto detect the HDD, set up your bios parameters, save and reboot with boot disk...at the A prompt type "sys c:" after it says files transfered and A prompt returns type "fdisk/mbr" then when A prompt returns reboot without the boot disk inserted and you should start win-dows and the process of autodetection will then start and you can then once windows goes to desktop, shut down and install your other cards and devices...hope this helps
-----------------
Q But, what does the "sys c:" command do? Also, why would I want to fdisk my master boot record?
sys C: transfers the system files and Fdisk MBR removes corrupted boot records caused by the swap... I know that this works but Im a master auto technician not master computer geek..just know it works from experience and great advice I have recieved over the past couple years working the computer tech board at E-bay..

Q: As a reseller we are often asked to upgrade someones motherboard. Sometimes it is a breeze and other times the only hope seems to reinstall Windows from scratch. Am I missing someting? Does anyone know of a site that has a FAQ on MB swapping or lobotomys ??
I thought a site like this might have people who try this all the time!
thanks
A: This procedure works most of the time, but always backup whats important:
Open registry editor
open HKEY_LOCAL_MACHINE
highlight the ENUM key and delete it
It will remove everything windows knows about your hardware. Reboot, it will say your display adapter is not configured properly. Click OK, run through add new hardware wizard.
It will reboot alot, and after its done load video/sound/modem drivers.
