Looks like I have the RS Media's memory figured out, that is to say using bootstrap mode I can write something in to memory and its the same when I read it out again.

The two 16bit memory chips are connected in parallel to create one 32bit block of memory. So with a little bit of tweaking, the SDRAM initialization b-code now apears to work. Now If I can figure out how to initialize the EEPROM containing the bootloader, I should be able to read the contents.

Hopefully, figuring out how to initialize the EEPROM shouldn't be to hard, I know the default settings that are used to boot from EEPROMs, so I just need to figure out the bus width settings (there are only two it could be) and it should all be good.

I still haven't managed to write any b-code programs that work, but now that I have the memory all sorted, it shouldn't be to hard. I'm not entirely certain that I need to, since if I manage to initialize the EEPROM, I should be able to read out the contents without needing a special program.
