iPXE can't boot UEFI mode via USB key

[woodrowshen]

Hi all,

I was trying to follow these commands from https://gist.github.com/AdrianKoshka/5b6...2f8034539a to create a UEFI bootable key with iPXE:

git clone git://git.ipxe.org/ipxe.git
cd ipxe/src
make bin-x86_64-efi/ipxe.usb
sudo dd if=bin-x86_64-efi/ipxe.usb of=/dev/sdX

I'm sure that the machine I tested disabled secure boot and turn UEFI mode on, but I got the weird errors after booting up:

...
Fetching Netboot Image
Malformed binary after Attribute Certificate Table
datasize: ? SumOfBytesHashed: ? SecDir->Size: ?
hashsize: ? SecDir->VirtualAddress: 0x002E6088
Failed to load image: Invalid Parameter
start_image() returned Invalid Parameter
Could not boot image: Error 0x7f048282 (http://ipxe.org/7f048282)

Then I search the forum to see if any related topic but apparently not...
I just wonder if someone verifies iPXE UEFI with USB key rather than chainloading, becoz my purpose is to use iPXE to replace PXE on the machines without PXE support.

Btw, I confirm iPXE works well with legacy BIOS however I need UEFI mode.

Anyone can give suggestion or information?

Thanks,
Woodrow
