I do not work with PC at all so I can not answer any of your question
but I'm curious as to why you need u-boot if you have a standard PC.

That question is easy to answer - because U-Boot is so much more
powerful than any GIOS I've ever seen.

You need to get the data sheets of all the chips on your board, 
including any north bridges, south bridges, video chips (assuming you 
want to support video), memory (flash and SDRAM), and whatever other 
software programmable parts that are on your board.  You need this 
information in order to properly initialize the hardware.

The traditional BIOS does this initialization.  Since you desire to 
replace the BIOS with u-boot, you will have to do the initialization 
yourself.

The big problem is that full hardware documentation is hard to get. 
Depending on your board and the chips used on it, you might be able to 
get the documentation, but historically it is a show stopper problem. 
This may be changing with hardware becoming more open for linux drivers, 
or maybe you will get lucky...

Once you have the documentation, you will need to figure out exactly how 
your hardware needs to be initialized (registers, values, sequences).

Good luck,

With Linux running on your system (or booted via a Live CD like
Knoppix):

# lspci -vvv

That should reveal most of the major chips

Device manager on MS Windows may provide similar information.

You may have to physically identify on the smaller chips on the
board, since they will not be visible in lspci output.

Good luck!

First you should be sure if that's exactly what you want.  

If you just want to play with u-boot on x86, porting it to bochs (or another 
virtual pc) should be easier and have more benefits than your pc. 
http://bochs.sourceforge.net/

If you want free software to boot your PC, you should have a look at coreboot 
(linuxbios) as well. It can also boot other PC related (BIOS dependent)  
operating systems, like freedos, which you probably wont be able to boot with 
u-boot. There is a port for bochs, so you can already play with it.

Getting a board which is already supported by Linuxbios should be the best 
starting point to port u-boot on it.

Good Luck
