Syslinux - Aug 2015 - uEFI PXE Primer/Examples

Patrick,

Even more confusing.  I downloaded the 6.03 syslinux tar and extracted all the
files.

It shows 3 pxechn versions, 

[root at localhost_PXENG ~]# cd /tmp/syslinux-6.03
[root at localhost_PXENG syslinux-6.03]# find . -name pxechn.c32
./efi32/com32/modules/pxechn.c32
./efi64/com32/modules/pxechn.c32
./bios/com32/modules/pxechn.c32

Is it possible to pxechn to a BIOS pxelinux.0?

 Where I need help is the layout of the uEFI default file and  proper use of the

 Been doing quite a bit of googling, but the uEFI pxe stuff  is sparse.

With Syslinux 6.03 you should use pxechn.c32 instead but please consider at the
moment they are both BIOS only modules.

Syslinux now creates 3 different sets of binaries: bios/efi32/efi64
depending on the pre-OS environment and architecture of your client
you must PXE boot the corresponding NBP and its associated binaries.

Please consider:
1) Today you can use ./bios/com32/modules/pxechn.c32 for chain-loading to
pxelinux.0 on a BIOS (32/64) PC

2) Today you can "not" use ./efiXX/com32/modules/pxechn.c32 for
chain-loading to
an EFI application on an EFI (32/64) PC.

Best,
