Hi All</font>
<br>
<br><font size=2 face="sans-serif">I've been using iPXE in our lab for
sometime without any problems but there are a couple of issues that have
been hanging over me that you may be able to help. </font>
<br>
<br><font size=2 face="sans-serif">1) When chainbooting VMware builds with
iPXE, the http download of the WIM image is pretty slow - probably just
a little faster than FTP.</font>
<br>
<br><font size=2 face="sans-serif">At first I suspected it was network
related but I tried building VMs on the same subnet as the IIS server
hosting the wimboot files and the performance is the same. Ive also managed
to build physical servers using identical scripts and the WIMBoot is lightening
fast.</font>
<br>
<br><font size=2 face="sans-serif">Is there anything specific I need to
do to accelerate the performance of HTTP download on VMs? I know its an
open question but I just wanted to ask if anyone knew of any known\obvious
issues and\or if this could this be related to chainbooting from
the default Vmware pxerom? This is with ESX 4.1 but ive tried with 5 with
the same results.</font>
<br>
<br><font size=2 face="sans-serif">2) Our existing PXE infrastructure is
based on Microsoft WDS services in legacy mode. It boots to an OSChooser
menu by default from which you can specify which image you want to kick
off.</font>
<br><font size=2 face="sans-serif">We want to add an iPXE option within
the menu options, as we have successfully managed to boot to pxelinux fine,
but for some reason iPXE refuses to boot from OSChooser.</font>
<br><font size=2 face="sans-serif">Again, just trying to find out if there
are any known issues with this or if im missing something from our config.
The sif file looks like the below:</font>
<br>
<br><font size=2 face="sans-serif">[OSChooser]</font>
<br><font size=2 face="sans-serif">Description = "iPXE 1.0.1 - WIMboot"</font>
<br><font size=2 face="sans-serif">Help = "Tries to chain ipxe.pxe"</font>
<br><font size=2 face="sans-serif">LaunchFile = "Setup\English\Other\1BE.x64\i386\ipxe.pxe"</font>
<br><font size=2 face="sans-serif">Version = "1.00"</font>
<br><font size=2 face="sans-serif">ImageType=Flat</font>
<br>
<br><font size=2 face="sans-serif">Help appreciated with either of these
issues.<br>
</font>
