Syslinux - Jun 2010 - PXELINUX 3.86 Boots Over HTTP, 4.00 Does Not

Hi ,

Thought I would keep the same topic as a previous post in June - still is a
problem with pre49

Setting dhcp options 209 and 210 is breaking gpxe/pxelinux - everything else
being the same, it works fine in 3.86 and not 4.00.

..Inserting following into pxelinux.gpxe ...
set 209:string pxelinux.cfg/default
set 210:string http://xxxxxxxx.xxx.xx.uk/pxe/

It is hanging with 'Trying to Load:' and then about 4/5 of a screen of
space before the cursor.

If I omit these two lines and instead have ...
chain ${210:string}pxelinux.0
.. it again hangs after fetching pxelinux.0 from the server.


I am assuming this is a bug...3.86 and 4 are both using 1.0.0 of gpxe by the
looks of things so assume it is the way its interacting with pxelinux ?


Thanks for the great work on all this!

The response on that posting is repeated at the bottom of this one.

That would be a bug.  What particular build of gPXE 1.0.0 are you using?

Hi,

Pre58 now boots ok, but when selecting something large from the menu (e.g.
trying a 100+Mb HDD image), it starts xfering data an order of magnitude more
slowly than normal, then says Ready when its only about 5% through getting it,
then says
"Failed to free base memory error xxxx:xxxx".
(Smaller files get same free base memory error too)

Regards
 
Rich

I *think* I have this figured out and released as Syslinux 4.00-pre57.

i have been have serious problem getting any version of syslinux builds to
boot an iso using memdisk and gpxelinux.0. you can read about my problems
here http://www.boot-land.net/forums/index.php?showtopic=11668&st=0

Any help would be great especially any from the developers as this can be
some problem with the current syslinux builds.
