Re: [CentOS] 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.

No, but I'll confirm your observation that the efidefault file won't be found unless it's located in the top-level tftp directory. -- Paul Heinlein heinl...@madboa.com 45°38' N, 122°6' W___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
