[ipxe-devel] In order to ooting ESXi mboot.c32 from ipxe enable IMAGE_COMBOOT in general/config.h

[Brandon Penglase]

Thomas,
	I decided to try this out to see if I could get the same
thing. Working with Michael and Robin in IRC, we actually were finding
things about the same time you were. Once I uncompressed the tboot.b00,
and renamed it back to what it was, it then found it as a Multiboot
image. 
	I then ran into another issue, where the number of multiboot
modules is limited to 8. You can change this in
arch/i386/image/multiboot.c (line 55), and see the comment there on why
it is set as such.  I raised mine to 70 (little bit higher then the full
amount of modules). Using the options that Robin provided earlier (with
9 modules), and DEBUG=multiboot, I get the following:

Using the full list of modules, they all load, but then it just sits
there again. 

Try increasing the max modules, and see if that helps.
