pxelinux 6.0.1 not booting

I boot ipxe (undionly.kkpxe - from the very latest git code as or 26 Aug 2013) --> pxelinux.0 --> (menu)

With old syslinux 4.0.3 all works fine

With current pxelinux.0 v6.01 & corresponding menu.c32 or vesamenu.c32 any workstation that ipxe boots will simply instatnly reboot (Realtek) or  just hangs (Broadcom) at the pxelinux 6.0.1 loading line

Am I missing someything else that might be needed in the new version?

The difference in size of vesamenu.c32 is massive (4.0.3 = 159kb, 6.0.1 = 26kb)

I need 6.0.1 to be able to boot wimboot

Hi Sebus,

I believe you can use c32 modules straight from ipxe cant you?

You need to turn on an option (comboot) when compiling your ipxe.

At least this is the way I understood this compiling option

Also, with latest syslinux distributions, it looks like you need extra files to boot.

Hence maybe explain the smaller size of vesamenu : bits of code may have been moved to other files.

But I need menu, I could redo ipxe menu, but have no time currently to deal with it & test it

Would be good to know what files are now needed for what used to be a simple 3 file solution

sebus

well either you re compile ipxe to support menu.c32 and then you get your "old" menu back

and/or

you find the proper files to put in your tftp root folder with pxelinux 6.x

I can re-compile, but how do I auto-invoke menu (like the pxelinux default) and make sure all the entries do work:

DEFAULT vesamenu.c32


  menu hshift 0
  menu width 59
  menu margin 8
  menu color title * #FFFFFFFF *
  menu color border * #00000000 #00000000 none
  menu color sel * #ffffffff #999999ff *
  menu color hotsel 1;7;37;40 #ffffffff #999999ff *
  menu color tabmsg * #ffffffff #00000000 *
  menu vshift 8
  menu rows 16
  menu helpmsgrow 16
  prompt 0
  allowoptions 1
  
MENU BACKGROUND pxelinux.cfg/boot.png
MENU TITLE SPGS PXE Boot Menu

   LABEL bootlocal
	MENU label Boot from 1st local active partition
	localboot 0
	timeout 80

   LABEL TinyCore-Ghost
        MENU LABEL TinyCore with Ghost
	kernel tinycore/vmlinuz
	append initrd=tinycore/core.gz cde vga=791 nozswap
	
   LABEL HTTP-grub.exe-win7pe
   	MENU PASSWD ***************
	MENU label Win7PE - command line
	LINUX grub.exe
	INITRD isos/win7pe.iso
	APPEND --config-file="map (rd)+1 (hd32); map --hook; root (hd32); chainloader (hd32)"

etc

i'll compile my ipxe with comboot option and will give it a try.

fyi, regarding your first post, i can pxe boot straight to pxelinux 6.01 with the following set of files :

-root

--ldlinux.c32

--libutil.c32

--menu.c32

--pxelinux.0

--pxelinux.cfg

---default

... but chain booting pxelinux 6.01 thru ipxe freezes my computer whereas it works fine with pxelinux 4.03

adding COMBOOT option to my ipxe did not do me any good either

echo "#define IMAGE_COMBOOT" >> config/local/general.h

make bin/undionly.kpxe

my ipxe code :

chain menu.c32 menu.cfg

/erwan

For information, chain menu.c32 menu.cfg works with syslinux 3.x

I read that syslinux > 3.x changed the comboot format hence breaking compatibility with ipxe

Question raised on the ipxe forums.

/erwan

Many thanks for your tests.

Makes me feel a bit better that it wasn't just me being silly. Pity, seems I will have to forget (for now) wimboot from the menu...

Seems that other things are also "broken" with 6.01

But maybe that would be possible

edit

I only tested 5.01, the above does not work, make it stop on black screen after downloaded lkrn

Will test with 6.01 tomorrow
