about the writing my own boot code but this may not be viable in the amount of time I have With all due respect <img src="images/smiles/icon_smile.gif" alt="Smile" title="Smile" /> , allow me to doubt that you will be able to write *something* that can boot and perform the operations you require in evensome moretime <img src="images/smiles/icon_eek.gif" alt="Shocked" title="Shocked" /> .
If you want to write your own software, it would be IMHO smarter to stand on the shoulder of the giants <img src="images/smiles/icon_wink.gif" alt="Wink" title="Wink" /> , like:

Or you might want to research (depending on the EXACT type of RAM modules on which you want to make the study/research) if some hardware *like* these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820227517
can be found/still exists/etc.
Or go for a "microcontroller development board", something *like* :
