No, sorry.

NeXTStep and OpenStep are the precursors of Mac OS X and are retail (abandoned but).

The source code of the bootloader evolved in the currently available at http://opensource.apple.com but who knows how much it changed.

However I can test it with any you want, and if you want to add me to instant messaging you could guide me in the debugging.

Hi Natalia,

Is nextstep/openstep something that can be freely downloaded?

It would help if you can extract some SeaBIOS debugging info.  I've
uploaded a SeaBIOS image with the debug level set to 8 and serial
debugging enabled.  It is at:


Can you use this image with qemu, add "-serial file:mylog" to qemu's
command line, and forward the resulting "mylog" file back?

Also, please include the full qemu command line that you used.
