first, i clearly misunderstood what you were asking about. we get a ton 
of emails regarding the legacy bios and based on your information i 
assumed that was what you were asking about.

second, the UEFI shipped with the Minnow is a reference implementation 
that was provided by Intel. all of the direct customers of minnow using 
it in products and our own in house development is all done with 
Coreboot, which leaves our experience with UEFI somewhat limited.

third, Circuitco in the past has primarily specialized in ARM, PowerPC 
and MIPS based designs. Minnow is the first x86 based design we have 
produced and with that fact in mind we are not as experience in the 
"typical" support questions revolving around x86.

michael - are you able to answer this?
