Few years ago I did a fair bit of x86 programming, but with the more recent CPUs and all the new instructions, I'd probably be bit out of it. Then again, wouldn't hurt having a look at it... who knows, maybe in a few years I could actually do something ;)
The problem. Basically I get the problem immediately when attempting to boot from an ISO image (the installation step). The image is a UBUNTU x86_64 installation disk. Pretty much instantly when I attempt to boot the window flashes by and in the original window I get the CPU reg dump with the exception 12. It works when using the unmodified version of QEMU. / Chris On Sun, 2007-02-25 at 07:25 +0200, Avi Kivity wrote: > Chris Stromblad wrote: > > Hi there, > > > > Just wanted to introduce myself to the list and also ask a few > > questions.
