[syslinux] PXELINUX 3.86 Boots Over HTTP, 4.00 Does Not

[Moore, Richard F.]

Hi,

Many thanks for continued help - I am updating to latest git thus, I thought pasting my simple script was easier than explaining;

cd /clonemod/bits/syslinux-4.00
rm -rf gpxe
git clone git://git.etherboot.org/scm/gpxe.git
cd gpxe
cp /clonemod/bits/syslinux-3.86/gpxe/pxelinux.gpxe ./
cp /clonemod/bits/syslinux-3.86/gpxe/gpxe.diff ./
cp /clonemod/bits/syslinux-3.86/gpxe/Makefile ./
patch -p2 < gpxe.diff
make

I then copy the gpxelinux.0 created to /tftpboot overwriting old one and test.
 
Nothing is modified except standard pxelinux.gpxe which is changed to;

#!gpxe
set use-cached 1
dhcp net0
set 209:string pxelinux.cfg/default
set 210:string http://xxxxxxxx.xx.ac.uk/pxe/
imgload pxelinux.0
boot pxelinux.0


(I then get the 0's - using latest git on 3.86 also does the same)
Building .lkrn images from the same git seem to work as expected.

I can do a packet trace if this doesn't help? 


Cheers

Rich

The "free base memory" error is an error, but it's not critical in any way.

The all-zeroes phenomenon is very odd; I cannot reproduce anything like
it.  It seems even more weird that it isn't preventing you from booting.

a) are you modifying the pxe script in any way?  If so, can you send the
complete gPXE script you used?
b) could you obtain a packet trace by any chance (e.g. wireshark)?
