RedBoot not saving boot script on Thecus N2100

Has there been any progress on going back to an older
version of  
RedBoot in order to be able to boot the Thecus N2100 from
the boot  
script? Also, do some Thecus N2100's have a serial header
actually on  
the SATA backplane instead of just the contacts where on
would be?  
Thank you.
