Thanks, as this was a new unit for me, I downgraded to OS4, ran the BIOS update and went back to OS6.

No need to downgrade to OS4.
Here's the add-on
The latest BIOS for the Ultra 4/Ultra 4 Plus/Pro 4 is from 23rd August 2011
You can install flashrom and dmidecode using apt-get, extract the contents of the add-on and run the command to flash the BIOS manually doing something like this:
# apt-get update
# apt-get install dmidecode flashrom
# cd /tmp
# wget http://www.readynas.com/download/addons/x86/4.2/BIOS_Update_Package_0.5-x86.bin
# dd if=BIOS_Update_Package_0.5-x86.bin bs=16k count=1
# dd if=BIOS_Update_Package_0.5-x86.bin bs=16k skip=1 | md5sum -
# dd if=BIOS_Update_Package_0.5-x86.bin bs=16k skip=1 | tar -xv
# tar -xvf files.tgz
# ls -lah /tmp/opt/biosflash
# flashrom --programmer internal -c SST25VF016B -w /tmp/opt/biosflash/RN_Ultra4_082311.ROM
Don't interrupt that last command. Updating the BIOS if interrupted can leave the system in a state where it will brick when next powered off.

Have you tried that method under OS 6.6.x? It didn't work for me because flashrom wouldn't execute. See Updating-motherboad-BIOS-from-OS6-can-t-get-it-to-work. There has since been a suggestion that a 32-bit C library is needed, but I have not tried that.
