[PATCH] support for gPXE and esxi5

Hi,
Found it !
The following pxe images DO NOT cause the ESXi install to hang
-rw-r--r-- 1 root root 60928 Dec 2 01:38 menu.c32
-rw-r--r-- 1 root root 26828 Dec 2 01:39 pxelinux.0
The following pxe images cause the ESXi install to hang with fatal error: 10 (out of resources) at tools.t00
-rw-r--r-- 2 root root 39188 Apr 28 2009 menu.c32
-rw-r--r-- 2 root root 14716 Apr 28 2009 pxelinux.0
No idea as yet which versions each of these are. The first ones are most likely the most recent
[root at Config tftpboot]# rpm -qa | grep syslinux
syslinux-4.02-4.el6.x86_64
The second one may be the one that comes with RHEL. Did I install cobbler before updating syslinux ?
Next question is why gPXE has the same problem.
I am using
-rw-r--r-- 1 root root 61361 Nov 30 09:33 undionly.kpxe
Maybe I need to try some different versions ?
Thanks
John

Sorry, My mistake,
PXE/ESXi 5 - OK
gPXE/ESXi 5 - Not OK
gPXE/ESXi 5/ESXi 5 - OK
It is an Intel card, Desktop Pro 1G.
I will start looking at some variations and try them out. There may be some different gPXE builds I can do. Maybe there is some UNDI variation.
Also an interesting comment from this blog
http://blog.markusbordihn.de/2009/04/gpxe-and-localboot.html
"Because pxelinux will unload from the memory before it load the chain.c32 it works without any problems and also the localboot has the full avalible memory"
I am wondering if gPXE somehow operates within it's own memory restricted environment.
Thanks
John

Is it an Intel NIC? I vaguely remember seeing a post somewhere about Intel cards allocating a huge amount of buffers, causing issues when booting on a kvm guest, however I can't seem to find it now.
Also, I'm not 100% clear on which situations are working for you and which ones aren't - #1 and #2 seem to be the same.
