From 483c3c06ab17f799ae02041ac0dd992142bcc305 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 21 Apr 2010 13:35:31 +0100 Subject: [PATCH] [romprefix] Provide indication of successful call to install_prealloc The existing "iPXE starting execution" message indicates that the BEV (or INT19) was invoked, but gives no indication on whether or not the iPXE source was successfully retrieved (e.g. from PMM). Split the "starting execution message" into "starting execution...ok"; the "ok" indicates that the main iPXE body was successfully decompressed and relocated.
