Syslinux - Sep 2015 - Pxechn.C32 working under Uefi

Hello


    


    I'm currently working on a project to rolling out a new TFTP boot
    server, for a fairly large infrastructure (>200 servers, >1500
    clients, with heterogeneous configurations/setups). We are using
    Syslinux version 6.03 for all the function within our TFTP server.


    


    We are using Ubuntu as our main TFTP server for most deployments and
    WDS for our Windows deployments. We can PXE boot from the ubuntu
    TFTP server using both legacy (bios) and Uefi. 


    


    We have pxechn.c32 working with pxelinux.0 to switch between the two
    system, but pxechn.c32 under Uefi come up with the folowing error
    "pxechn.c32: ERROR: Unable to retrieve first packet". I have seen
    that there was a message about this logged on the 28th August 2014
http://www.syslinux.org/archives/2014-August/022611.html,
    and  I would like to know if there have been any updated on this
    problem. 


    


    If I can help by doing some testing that would not be a problem, but
    I can not program. I probably could involve colleagues for in depth
    debugging or programming.


    


    Many thanks


    


    Jonathan.

I doubt there has been any update to pxechn.c32 for UEFI support. Maybe 
Gene can confirm.

If you are trying to chain to another efi binary / image, perhaps this 
[1] PoC might help? If not for the exact goal, perhaps as an initial 
base so to make some new c32 module for UEFI systems?

@Developers, please consider using 8.3 file names format for c32 files 
instead of such a long file name.
If possible, also use short names for source files too. TIA.

Regards,
Ady.

Example of such a long file name?

So we know which file name to surpress into 8.3.
( yes, CP/M file name convention legacy is still present )

Euh, please visit
http://www.dmst.aueb.gr/dds/pubs/conf/2015-MSR-Unix-History/html/Spi15c.html
scroll down to '4 Data Uses', check the graphic, especial file name
length.

My point: _Why_ restrict the development system  file name length?



And now something completely different:

What is the value quoting those lines?

No.  pxechn.c32 is BIOS only for now.
