From 1056a1c2d576a704b8213fd769fb241b4a24a91e Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Fri, 29 Jan 2010 18:33:08 +0000 Subject: [prefix] Remove unsupported ELF prefices The .elf, .elfd, .lmelf, and .lmelfd prefices were brought over from legacy Etherboot and they do not build in gPXE. This patch removes the ELF prefices.
