<div dir="ltr"><div><div>Hello All<br></div>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. <br>
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. <br>
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.<br>
<br></div><div>I followed <a href="https://github.com/migle/BootDuet/blob/master/INSTALL" target="_blank">Migles BootDuet</a> <br><br></div><div>user#cd BootDuet<br><br></div><div>user# dd if=/dev/zero of=/dev/sdb bs=3M count=1 && cfdisk.gnu /dev/sdb<br>
<br></div><div>Under which I created a msdos table, setting up a fat32 partition & 'boot' & 'lba' flags<br><br></div><div>user#make lba64<br><br></div><div>user# make DEVICE=/dev/sdb1 install-bd32_64<br>
<br></div><div>then disconnected my USB & reconnecting<br><br></div><div>user# mount /dev/sdb1 /mnt/windows && ./copy_duet_files.sh /mnt/windows/ UDK_X64<br><br></div><div>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 help here.<br>
