+Package:     lilo
+Subject:     remove obsolete bios workaround
+Author:      Joachim Wiedorn <ad_debian at joonet.de>
+Forwarded:   yes
+Last-Update: 2011-01-18
+
+In the changelog of Debian lilo 22.2-3.1 (from 2002-05-10) was noted:
+
+  * This upstream version uses int15,0xe820 to fetch the memory map.
+    However, sufficiently many systems don't implement this interrupt
+    correctly.  We avoid the errant code for now.  The next upstream
+    release fixes this problem for real.  Note to Russell: this patch
+    must be removed for the next upstream release.
+
+Unfortunately nobody had remembered to this note and removed this 
+workaround with the new upstream release. But the upstream release
+22.3 (from 2002-10-19) of have the following note in its CHANGES: 
+
+    - Compensate for buggy BIOS in int 15h, fn E820h call to avoid
+      overlapping memory areas
+
+Now I remove this very old workaround because it is obsolete since
+May 2002!
