If you need to ask this question then I only have two suggestions:
a) Just get a new motherboard.
b) Find someone with the right skills and equippment willing to this for you.

For everything else I only see total failure coming :(

Also, "The ROM chips contain instructions, which are specific for that particular motherboard. Those programs and instructions will remain in the PC throughout its life; usually they are not altered." from

Karbosguide.com - Module 2a.1 - The PC and its motherboard http://www.karbosguide.com/hardware/module2a1.htm

A new MB will have its own ROM, so why replace it with one that was not designed for the new MB? So, even if the ROM transplant is successful, the result probably won't be.

See above.

I guess it for a "repair" of a failed flash attempt.
People love overclocking these days, try flashing all sorts of roms and if something fries it you need to get an identical chip to get the board going.
Back in the old days we did that and once all bios settings were correct the chip was hot-swapped for the faulty one and the settings saved.
These days not only next to impossible but also not really worth it.
A good board has dual bios and if the user kills both then he really should buy a new motherboard as a learning experience.

Well, as recently as 2013, and on an ASRock board, ROM's are still still EPROM chips with legs that you pry up carefully. from the socket. You don't suppose they are trying to un-solder the socket?
