I’ve also been wondering about that. Comparing the patches, I believe that, when skipping the menu, the only difference is that Jarek additionally sets the sname field, while I only set siaddr and file. I think Jarek said that without sname, some of his clients didn’t boot. I think it would be fine to add the sname line to my patch and hopefully that should fix Jarek’s clients too without needing all that pxe_skip_menu code.

Absolutely. <name>.0 is correct for x86 BIOS and <name>.efi is correct for EFI on any platform. Not sure about other (less common) platforms, but the current <name>.<numeric ID> is probably not right for anything except x86 BIOS.

If you have access to a recent version of VMware, I can send you a VMX file and an EFI binary for testing.
