PXE 6 hangs

[andyj]

I've been using the old pxelinux.0 version 4.06 for a while now and it works fine:

Code: [Select]

As I'm trying to update the various parts of my systems I'm trying to migrate to pxelinux 6.03 in the syslinux extension. The problem is that it hangs after it displays the first line showing the version (so I know that part loaded OK). I read that I have to have ldlinux.c32 in the TFTP root, but it doesn't seem to get that far. I'm using busybox udpsvd for tftp so its logging leaves something to be desired.

I never use PXE, but I believe you'll need to update your syslinux.

For example, legacy BIOS with extlinux:

Code: [Select]

dd if=/usr/local/share/syslinux/mbr.bin of=/dev/device bs=440 count=1
extlinux -i /path/to/directory

BTW, you might need to add more modules.
Maybe this would help.
