GitHub PR #235 adds an advanced boot mechanism for UEFI machines which causes old Legacy BIOS nodes to hit the 3 GB RAM barrier in 32 Bit iPXE very quickly. Therefore, detect if an EFI or Legacy BIOS is loaded and fall back to the old boot path in the second case. This commit fixes GitHub issue #497.
