Problem was in unconditional reboot after BIOS POST. Last message was: "iPXE (PCI...) starting execution..."

All our Option ROMs has been burned into BIOS ROM. Currently I've found only one Mobo without PMM support. I will look closer to the original PXE ROM. IBA on BIOS w/PMM is complain about PMM support.

Could it be a problem with new layout introduced with this commit to be out of available space?
I'll check unmodified iPXE on BIOS w/PMM to confirm.

Anyway, I will try to pressure Asus to fix the BIOS :)
