Subject: [Qemu-devel] SPARC patch for OS X (big endian machines)
Date: Tue, 27 Sep 2005 16:58:06 -0700 [thread overview]
Message-ID: <8c2b58c5dbd7bef1e6dd8fa31c9f2d41@soe.ucsc.edu> (raw)
Without the following patch, I was unable to "start" the Linux boot
process
on OS X (powerPC bigendian). I tried on ia64 (Linux) and works fine too.
