[syslinux] Using syslinux on the PMBR of a GPT partition table

[Stewart Adam]

Hm, I must have made a typo and put /dev/sdb1 instead of /dev/sdb because I 
did trials again today and it didn't work.

I copied the example from Wikipedia which gives the 16-byte binary version 
of the GUID for the EFI system partition [1] and added it to gptmbr.bin with 
a hex editor, and the final size was 440. I've double-checked the 
partition's GUID and it's the same under OS X and parted.

Is there anything else I can to to help you test or pinpoint the bug?

Thanks,
Stewart
