[syslinux] Chainloading / Nested PXELINUX

[msacks]

Hi List,
Is there a proper document on how to chainload two PXELINUX boot configs?
I have one tftpboot root and I need to nest another one inside. The
second nested PXELINUX root has different custom boot images, but I
need to access it from a menu system.

I need to call 2 from within 1, but I am not sure how to go about this
or if it is even possible?

Thanks in advance.
