This page will help you get a look at the XO software, by running a "virtual XO" in an emulator. |
|||
Another option is burning a [[LiveCd]]. |
|||
== What to expect == |
|||
This "virtual XO" was created as a software development tool. It is not intended for general use, and many things will not work. It is "just to get a taste" (and to help software developers). With time and people constraints, we are focused on the real XO. |
|||
*The camera and video will not work. |
|||
*Things are slower than on the actual machine. If you are unable to install qemu's kqemu accelerator, very much slower. |
|||
*You will see a snapshot of the past. The instructions will have you download the "latest stable build", which is sometimes quite a few weeks old. Development is very rapid. Things will be missing or different compared with the present. |
|||
*While rapidly maturing, this is still "alpha" software. |
|||
*TamTam, the popular music program, will likely not work (no sound). |
|||
== Four steps == |
|||
First, download |
|||
[http://olpc.download.redhat.com/olpc/streams/development/LATEST/devel_ext3/olpc-redhat-stream-development-devel_ext3.img.bz2 olpc-redhat-stream-development-devel_ext3.img.bz2]. It is in [http://olpc.download.redhat.com/olpc/streams/development/LATEST/devel_ext3/ this directory]. |
|||
Second, get the qemu emulator which will run the image: |
|||
*[[Using QEMU on Windows XP|Windows]] |
|||
*[[Emulating the XO/Quick Start/Mac|Mac]] |
|||
*[[Emulating the XO/Quick Start/Linux|Linux]] |
|||
*[[Emulating the XO/Quick Start/Linux#FreeBSD|FreeBSD]] |
|||
*[[Emulating the XO/Quick Start/Linux#Yellow Dog Linux on PlayStation3|Yellow Dog Linux on PlayStation3]] |
|||
Third, extract the .img file from the .bz2 file. |
|||
Fourth, run: |
|||
qemu -m 256 -kernel-kqemu -soundhw es1370 -net user -net nic,model=rtl8139 -hda olpc-redhat-stream-development-devel_ext3.img |
|||
If qemu responds with an error like "qemu: could not load PC bios '/c/Program Files/Qemu/bios.bin'" then you may have to use qemu's -L option to specify the directory where you installed qemu, which contains the bios.bin file. If you're using a 64 bit processor, you need to run the command 'qemu-system-x86_64' instead of 'qemu'. |
|||
Note that qemu by default gives 128 MB RAM, but according to [[Hardware_specification]] recent XO HW have 256 MB, that's why the "-m 256". To test for early XO HW (or later with more), change the -m param. Giving 256 MB RAM appears to have a noticeable effect on speed in the emulator (as I'm sure in the real HW ;)). |
|||
You should now have a running "virtual XO". |
|||
== Running for the first time == |
|||
[[Sugar Instructions]] will help you get oriented, though you may not need it. |
|||
You can also get other [[Emulating the XO/Help and tips|Help and tips]] on emulating Sugar. |
|||
When running under emulation, the sugar fonts will appear very tiny until you [https://dev.laptop.org/ticket/3681 set the screen to 200 dpi]. |
