[syslinux] UEFI http issues

[Dave Henderson]

Hey Tim,

I just saw this on the syslinux wiki:

https://wiki.syslinux.org/wiki/index.php?title=PXELINUX#HTTP_and_FTP

"While using HTTP/FTP (syntax), trying to use pxelinux.0 (i.e. without
the letter "l" prefix) without iPXE/gPXE running underneath, will
result in a "file not found" warning without any explanation as to the
cause! "

I can see that you are currently using the 'lpxelinux.0' file.

Not sure if this helps or not...

Dave
