[PATCH] support for gPXE and esxi5

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.
