EFI firmware bug on HP EliteBook 2560p / 8460p

[ppat]

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.

I have traced the problem to:

/syslinux-6.03/efi/udp.c\core_udp_open()
/syslinux-6.03/efi/main.c\efi_create_binding(&Udp4ServiceBindingProtocol, &Udp4Protocol);
/syslinux-6.03/gnu-efi/gnu-efi-3.0/lib/hand.c\LibLocateHandle(ByProtocol, bguid, NULL, &nr_handles, &handles);

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.

Thanks

Patrick

Hello

Thank you for posting on the HP Forums.

To get your issue more exposure I would suggest posting it in the commercial forums since the EliteBook 2560p/EliteBook 8460p are commercial products. You can do this here: Notebook - HP ProBook, EliteBook, Compaq, Slate/Tablet PC, Armada, LTE

The support page for your products may be helpful in the meantime:

HP EliteBook 2560p Notebook PC

HP EliteBook 8460p Notebook PC

I hope this helps!

Thanks for your answer but my previous experiences with HP community based forums were a complete waste of time.

Hopefully someday someone at HP will see this report and eventually do something.

Thanks again

8460p/2560p EFI firmware is really spartan; Booting into an UEFI Shell and listing the handles with

shell> dh

I can clearly see there's not a single Service Binding Protocol implemented.

HP this firmware is really not UEFI compliant at all..

Note: Tested on a Elitebook 8460p with Firmware F.60 Rev.A (31 Mar 2015)
