Re: [openfirmware] Unable to run OFW on Qemu
Do a "svn update" to pick up my latest changes and try the "BIOS" version again. Let me know if you have any problems. I fixed a regression caused by some changes that I made several months ago. By the way, you can see OFW's early startup progress if you add "-serial /dev/tty" to the qeme command line. That's how I debugged the problem. - Mitch On 11/22/2012 3:22 AM, aditya siram wrote:
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.

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.

That worked. I appreciate your support. My next step is to boot into OFW from a flash drive. Thanks! -deech On Fri, Nov 23, 2012 at 6:41 PM, Mitch Bradley <wmb@laptop.org> wrote:
