I have installed Windows XP and OpenDarwin 8.01 x86 on one harddisk and I can boot them dual.
My computer is:
Intel Pentium 4 2.4 GHz
512 MB RAM
64 MB Nvidia Grahipcs
80 GB Maxtor Harddisk.
I will try to explain how I did it:
I have partitioned my harddisk into two partitions (one is 70 GB and the other is 10 GB).
First of all I have installed Windows XP on the first partition.
After the installation of windows, i formatted the second partition from windows as fat32 or ntfs (not so important).
This partition is a primary partition, and i don't know whether it is important to be a primary or an extended partition or not.
I then boot with OpenDarwin 8.01 x86 install CD (you can download it from http://www.opendarwin.org.
(Note: I have a usb mouse and ps/2 keyboard. after i boot with opendarwin CD i could not use the keyboard. then i put my usb mouse into the mouse ps/2 by an usb to ps/2 adapter. then i reboot with CD and voila... )
Then Opendarwin asks :
"The following devices are available for installation:
1. Maxtor ....
Which device would you like to install Darwin onto? "
And you must choose the harddisk where Windows is installed.
The next question is:
"For partitoning the disk, you have the following choices:
1) Auto-partition the disk ...
2) Manually partition the disk ....
3) Use existing partitions "
You should choose "3) Use existing partitions"
The next step is :
"The following partitions are available:
Which will be the root partition?"
You should choose now your second partition.
And then it asks the type of filesystem:
hfs+ should be chosen.
And then you should choose clean install.
And then the installation starts.
After the installation you reboot your computer.
At this step you can not boot opendarwin but you can boot your windows xp.
start your windows.
In the opendarwin installation CD there is a boot file(its name is chain0) for open darwin in the following location:
copy the file "chain0" into the C:\
and then edit C:\boot.ini with your editor write the following lines at the end of the file:
C:\chain0="OpenDarwin 8.01 x86"
and then save it.
and that is all. the next time you turn on your computer, you will see a boot menu and you can choose opendarwin and boot it.
enjoy your opendarwin
