ISOs for Macbook without optical drive
Q: Does this Linux ISO support booting off a USB pendrive on a Mac EFI?
(I don't want no BIOS jail, that shit drove me insane about 8 hours ago and I'm out of coffee now)
A: Simple! Yes if it starts with ER. No if it doesn't start with ER.
Examples:
% (dd bs=8 count=1 2>/dev/null|xxd) < Fedora-17-x86_64-Live-Desktop.iso
0000000: 4552 0800 0000 9090 ER......
===> That's a yes.
% (dd bs=8 count=1 2>/dev/null|xxd) < openSUSE-12.2-NET-x86_64.iso
0000000: 33ed fa8e d5bc 007c 3......|
===> That's a no.
