In late May of 2011, Brian Vandenberg queried this group about failures
he was having trying to install Solaris 8 SPARC 02/04 on a Qemu VM. The
interaction seemed to have ended with Blue Swirl indicating that Brian
should run with "-d in_ascm,int" and that the debug output would likely

this feature as there has been some discussion lately
if multiwrite is a good idea at all and as it falsifies
