Well, if it is coming up with a Rio logo instead of an Empeg logo, it is a Mark2A (unless this was specifically changed by you or a previous owner). As for the boot log, you should connect in with Hyperterminal, watch and save the startup to a capture file and post the contents of that file to the board. If a drive is not being found (a likely cause for the type of error you are seeing) it will be very obvious in that log file.
