Status

As of January 2010, Q.app still uses qemu 0.9.x, whereas PureDarwin needs 0.10 to function properly. Hence, we recommend to use QEMU instead for now.

The latest version (Q-0.9.1d118) has been updated last year, creating a big gap between the latest official QEMU and the one used in Q front-end. Consequently, Q is not usable for PureDarwin at this time.

We also tried to replace i386-softmmu with a newer version inside Q.app but no success since the usage is different between both parts (and also the features supported). UI

Please, let us know if you have a solution.

Chameleon bootloader

SMBIOS well-known problem is bypassed with Voodoo kernel (xnu-dev).

Then, the real boot begins, but quickly ends with a problem related to APIC similar to the one in VirtualBox page.

Then, with <string>-f -v -x cpus=1 busratio=16 io=0x21</string> in /Library/Preferences/SystemConfiguration/com.apple.Boot.plist, things go far:

The goal of this project is to make Darwin more usable by providing an installation ISO, documentation, and add-on software. You are welcome to join #puredarwin on irc.freenode.net or the Gitter chat if you would like to join PureDarwin development and to add to this site.

The Wiki pages were recently moved from Google Sites and in the conversion process some formatting was lost. Please help fixing the markdown of this page by editing it. But please delete nothing, especially not (broken) images; fix them instead (see the main page of the Wiki for an example).
