[coreboot] Annoying DUET UEFI failures

Well sometime back I had successfully build the DuetPkg on both IA32 & X64
architectures. Futher experimenting I came across the build32.sh which
enabled me to prepare the efiloaders & floppy images without the need to
follow their manual setups. Well after setting up my USB flash for DUET &
booting I faced a freeze problem like a hyphen in the left side corner. It
would get stuck there until I restarted & so I was unable to figure the
problem at all. However getting to qemu to boot it seemed just successful &
capturing debugging messages was just useless.
Thus Goggling a bit I came across rod books a BIOS to UEFI Transformation
wherein it was mentioned that one of the versions may succeed i.e. either
2.1 or 2.3.1 so I figured out it between EDK_UEFI64 & UDK_X64 (resp) &
decided to go with the 2.1 version & there it just booted successfully.
I dont know why there is a failure between EDK_UEFI64 & UDK_X64. I had
last time falsely implicated it to be a EM64T error which I had noticed on
Oracles VM Box but my processor (Intel Pentium D) readily supports it. By
the way this how I had set up the USB.
I followed Migles
user# dd if=/dev/zero of=/dev/sdb bs=3M count=1 && cfdisk.gnu /dev/sdb
Under which I created a msdos table, setting up a fat32 partition & 'boot'
& 'lba' flags
user# make DEVICE=/dev/sdb1 install-bd32_64
then disconnected my USB & reconnecting
user# mount /dev/sdb1 /mnt/windows && ./copy_duet_files.sh /mnt/windows/
I hope so someone on this mailing list would help me solve my problem. I
know that I should have posted this on the edk2 mailing list but since the
DUET setup has been a part of the coreboot development I decided to ask for
