Subject: [Qemu-devel] PPC little-endian mode support
Date: Mon, 18 Apr 2005 10:36:38 +0200 [thread overview]
Message-ID: <1113813398.11980.94.camel@rapid> (raw)
[-- Attachment #1: Type: text/plain, Size: 260 bytes --]
This patch adds little-endian mode support to PPC emulation.
This is needed by OS/2 and Windows NT and some programs like VirtualPC.
This patch have been tested using OS/2 bootloader (thanks to Tero
Kaarlela).
