winrar vs 7-zip

I had changed winrar to 7-zip simply due to it being a more open tool and overall has better support than winrar in terms of usable archive formats, however I noticed great work went into the tutorial that was winrar specific, I might consider changing that later if there is no problem with that

  • I'm not sure what the format is for discussions, but some thoughts:
  1. Why encourage using 7-zip? Shouldn't most users already have winzip installed? winzip also unzips .bz2 well enough.
  2. Which image should I be using exactly? After a couple of passes, I'm attracted to the little green box with the os711.img, which seems to be the latest build, but that seems not to be a bootable disk. However, any of the other images provided on the page works. Is there a way we can just link to a page that will constantly provide the latest image, or will this page be constantly edited when new images come out?
  3. Other than that, I thought the instructions were great, and I especially like the .bat file at the end.

8.2.0 images

There are some known issues (#8369) regarding emulating 8.2.0 builds, message from Ton regarding these problems and a workaround pasted below. 

You (and anybody else interested) can find my version of QEMU for Windows
which runs 8.2 and joyride images successfully here:
http://www.v-overbeek.nl/XO-1/qemu-svn-4887-for-windows.zip .
Below the README from the zip file:
=========================================================================
       QEMU for running 8.2 XO-1 devel-ext3 images on Windows
       ------------------------------------------------------

Here is my privately compiled version of qemu based on snapshot svn-4887.
See http://savannah.nongnu.org/svn/?group=qemu .
I have only used it on Windows XP/SP2, but it most likely will work under
Windows Vista.

Installing qemu
---------------

Make sure the following files are all in the same directory:
qemu.exe
fmod.dll
SDL.dll
mwgz.dll
bios.bin
vgabios-cirrus.bin
qemu-img.exe (optional)

This will allow you to run qemu, but slowly. It is recommended to use the
kqemu accelaratiob module. You'll find a version compatible with this version
of qemu in the subdirectory kqemu-1.4.0pre1.

Before installing this version, uninstall any previous versions of kqemu !
The kqemu supplied with the released 0.9.1 version is not compatible
with this version of qemu.

In the kqemu-1.4.0pre1 directory right click kqemu.inf and select Install.
See also http://bellard.org/qemu/kqemu-doc.html .

The service can be started by the command 'net start kqemu'. it should report
"The KQEMU virtualisation module for QEMU service was started successfully."
on Win XP/SP2

Running qemu
------------

Make sure the kqemu accelerator is running (see above).

To run qemu for an XO-1 image use  commands like:
------
net start kqemu
qemu -L . -cpu athlon -m 512 -net nic,model=rtl8139 -soundhw es1370 xo-1-olpc-stream-8.2-763-devel_ext3.img
------
The important option is '-cpu athlon'.
If you forget this option you will get the following messages:
       This kernel requires the following features not present on the CPU
       3dnow
       Unable to boot - please use a kernel appropriate for your CPU.

For other options see the qemu documentation.
