this is the reason why before i got hybrid sleep working, i only use foxconn motherboards for carpc. I remembered trying to track down one of these a while ago when i was purchasing a new carpc, but there weren't any of these boards close to north america.
I'm still using a foxconn motherboard (R10-S4 Barebone) with almost the same spec as your except with more sata connection. However the R10-S4's bios was disappointing compared to the CSX-45 in term of boot time. Then i figured out how to use hybrid sleep, which is now like 1 second bootup.
