Thanks, its loading the menu now, however, I appear to be hitting the same
problem I was going from grub to ipxe. The adapters are there, but won't
autoconfigure, and if I try to manually set an IP address, I see the debugging
data start spewing from ipxe (which appears to be still running underneath
grub) before the system eventually halts.
I'll try your rollback, but was it mean to come out in the email as a long hash
string?

Subject: Re: iPXE efi chainloading grub2 pxe efi file

I've got a good working EFI Grub2 efi Bootloader that works fine when its
directly handed off to by the DHCP for PXE, however, if I attempt to chainload
it from iPXE snponly.efi, it goes straight to the grub command prompt.
I've tried embedding the grub.cfg file via -c on the grub-mkimage command, but it spews
out the grub file as a stream of "command not found prompts" and then still
goes to the grub command line.
Embedded config is processed very early, before normal.mod is loaded, so only
commands available at rescue prompts are present.
If I try embedding all of the modules directly into grub.efi during mkimage,
along with the config file, it then throws a grub_divmod64_full not found error.
Embedding all modules in grub.efi is usually wrong (not all modules can be
loaded concurrently) either.
Try creating standalone image with grub-mkstandalone. This image contains all
grub modules in memory disk (as cpio archive) and grub is configured with
$prefix pointing to this disk. You can also add own files, in particular put
grub.cfg in memory disk.
What is the ideal way to chain load my grub.efi file from iPXE so that it works
the same as if it was the direct handoff from the DHCP/TFTP server?
Unfortunately, in order to allow for selecting either our EFI WDS Server or our
EFI Linux Server, I have to use iPXE first, as chainloading snponly.efi from
grub2 ends up with iPXE snp not being able to enumerate anything from the PCI
Bus.
Hmm ... this actually sounds like exclusive SNP open (used by both iPXE and
GRUB) messes something up. For testing you could try to revert
49426e9fd2e562c73a4f1206f32eff9e424a1a73 (and
f348aee7b33dd85e7da62b497a96a7319a0bf9dd which depends on it) to see if it
makes any difference.
Using git pulls for both that were from yesterday.
