From 9a5b4aed69a31a49937dbbaaa9bab80725ce1d9c Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Thu, 10 Mar 2011 22:50:05 +0000 Subject: [PATCH] [bios] Use INT 16,11 instead of INT 16,01 to check for keystrokes INT 16,01 will discard some extended keystrokes on some BIOSes, making it impossible for iPXE to detect keypresses such as F12. Fix by using INT 16,11 instead.
