Currently the Fedora 35 ship with SYSLINUX version 6.04 
When you use Cobbler to pxe boot system will see below message continue print on screen

Failed to load COM32 file  ..../mboot.c32

It is because VMWare build their own mboot.c32 and don't release source code.

Solution:
    Copy pxelinux.0 from old syslinux package and put it to /var/lib/tftpboot/ , I tried 4.05 from CentOS 7 default repo. and it work!
