PXE Booting UEFI
Good Afternoon,
As per the installation guide, section 30.2.2 I’ve created an efidefault file at /var/lib/tftpboot/pxelinux/pxelinux.cfg/efidefault
However, this file is never requested by the 64 bit PXE loader (bootx64.efi), as shown by tcpdump:
75 RRQ “/pxelinux/42272635-0011-5053-ACF2-82A100E615F2” octet tsize 0 blksize 512

42 RRQ “/pxelinux/C13” octet tsize 0 blksize 512
41 RRQ “/pxelinux/C1” octet tsize 0 blksize 512
40 RRQ “/pxelinux/C” octet tsize 0 blksize 512
49 RRQ “/pxelinux/efidefault” octet tsize 0 blksize 512
I’ve worked around this by placing a separate efidefault in the root of the pxelinux directory – however this is undesirable as this means I have to maintain separate configs for BIOS and UEFI.
Does anyone know why this is not behaving as documented?

One thought on - PXE Booting UEFI
IIRC the line
49 RRQ “/pxelinux/efidefault” octet tsize 0 blksize 512
In the output below means look in
/var/lib/tftpboot//pxelinux/efidefault Not
/var/lib/tftpboot//pxelinux/pxelinux.cfg/efidefault i.e. it is rooted at the root of your TFTPboot structure.
