Unable to run OFW on Qemu
by aditya siram Nov. 22, 2012

Nov. 22, 2012

Hi all, I was trying to get OFW running on Qemu to play with it and have been unsuccessful so far. My OFW is the latest Subversion as of yesterday. When I follow the instructions for creating a BIOS [1] or a floppy [2] I get a black non-responsive screen. Running `strace qemu-system-i386 -L /usr/local/share/qemu -boot a -fda floppy.img` I can see that it's stuck in some loop [3] but I can't tell what it is or how to fix it. I think that Qemu itself works because I booted it with one of the linux test images available for download from their site and it works fine. I'm using a Thinkpad X200 with Ubuntu 12.04 and kernel version 3.5.0-18-generic and Qemu version 1.2.1.
