Back in those days I made my living assembling and repairing those XT machines. 
 The motherboards were almost universally from a handful of manufacturers and 
generally referred to as "Turbo Motherboard XT."
I never saw any type of daughterboard.  Generally they had a switch that 
selected "normal" (4.77 mhz) or "turbo" (8 or 10 or rarely 12 mhz.)
Is this message you are getting a bios message or is it from dos trying to 
load?  If it is bios, it is something I have never seen.  If it is from dos, it 
should be easy to get around it.  The bios on almost all of them was either 
ERSO, Award, or Phoenix.
But my memory is starting to fade after 35 years.
