You will also need following blobs:
descriptor + me firmware
VGA BIOS
cpu microcode
All are extractible from original BIOS by using the extract tool I
published previously. cpu_microcode
(UUID=3030435f-0000-0000-ff00-000000000000) has a range of ff...ff at
the beginning you have to strip.
VGA UUID is 3030525f-0000-0000-ff00-000000000000.
descriptor and me firmware are files 001_descriptor.bin and 002_me.bin
