I may not fully understand your problem, but wouldn't FAI just detect the availability of UEFI (via /sys/)? Everything else should be handled by the DHCP/TFTP server side (which is only closely related to FAI). Whether there's a 64-bit system installed depends on the NFSROOT assigned. But since you want to talk to the 32-bit UEFI first, perhaps the following years-old snippet from my dhcpd.conf may point you in some direction: ... ## https://www.syslinux.org/wiki/index.php?title=PXELINUX#UEFI if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00000" { filename "pxelinux.0"; } if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00006" { filename "syslinux32.efi"; } if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007" { filename "syslinux64.efi"; } if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00009" { filename "syslinux64.efi"; } ... You may have to look for ldlinux.* and syslinux*.* files in various subtrees provided by the syslinux-common package, and copy them into your TFTP tree.
