I am a UEFI/BIOS developer. We UEFI PXE boot dozens of times per night. We have run into this error more than a couple of times. We have also done thousands of UEFI PXE boots with debug statements to prove that the patch works.

Sometimes the UEFI memory map changes between GetMemoryMap() and ExitBootServices(), making the MapKey value incorrect. Per the UEFI spec, the memory map should then be fetched again and exiting retried.

This patch adds to Com32 modules the capabilities of accessing the EFI environment The idea is simple, the EFI parameters "image" and "table" received by syslinux.efi's efi_main() are stored in the "firmware" structure, next they are retrieved from the Com32 module which is linked against the gnu-efi static library. The Com32 module can use the EFI

This patch adds to the core EFI image booting capabilities. It was tested on VMware EFI clients and HP Elitebook EFI notebooks, only on PXE environments but it should work on non-PXE scenarios as well. Feedback appreciated.

>>> Lovely, the ServiceBindings are on a handle that resembles the NIC while the Pxebc is IP-type specific.? Looks like we should try to do a ServiceBinding based on Pxebc but fall back to MAC-based searching, saving all 3 handles, the image handle, Pxebc handle, and ServiceBinding handle.? Presumably the UDP and TCP handles _should_ be the same... -- -Gene <<< OK now it

>>> I'm just debating what's the best algorithm here.? It would seem if the LoadeImage's DeviceHandle provides UDPv4Sb, use it as it's guaranteed to be the same interface.? Otherwise, we need a MNPSb (EFI_MANAGED_NETWORK_SERVICE_BINDING) that provides UDPv4Sb across the same interface.? Presumably it should also provide TCPv4Sb (rather than being on a separate
