[ipxe-devel] Query on UEFI iPXE boot

[Sanjeev.Roy at Emulex.Com]

Hi Michael,
Couple of queries related to UEFI NIC boot using iPXE.

1. Is chain loading supported for UEFI in iPXE environment? Lagacy PXE boot (chain loading) works fine.

2. We build 808610de.efi from the source files. Could you please let me know if this file would work in case of UEFI boot for any adapter (we are trying this with an Emulex adapter). Do we need to build this efi file separately using our device and vendor id?
If yes, could you please let us know how we can build this for our adapter?

Regards
Sanjeev

That looks as though it should work.

You can also use DHCP option 93 to determine whether a request comes from a 
BIOS or EFI client.
