Hi there, I have experienced problems with UEFI firmware on HP Elitebook 2560p and 8460p Latest firmware installed: 2560p 68SSU ver. F50. 08/04/2014 8460p 68SCF ver. F50. 08/04/2014 F.60 Rev.A (31 Mar 2015)
PXE boot syslinux.efi 6.03 syslinux.efi gets perfectly TFTP transferred but when running it fails asking for ldlinux.e64, and immediately gives up returning control as a failing efi application.
When gnu-efi (running last commit Feb 2015 ) LibLocateHandle() function tries to locate EFI_UDP4_SERVICE_BINDING_PROTOCOL it fails with EFI_NOT_FOUND (14) which looks like an HP firmware issue; Does the NIC EFI Driver on these PCs correctly implement the Service Binding protocol?? On the same test newer versions of the HP Elitebook family like 2570p and 8470p PXE boot syslinux.efi correctly. Please let me know.
