[LinuxBIOS] Booting Windows with QEMU+LinuxBIOS

[Jun Koi]

      Hello,

I am playing around with LinuxBIOS. The first step is to boot Windows
on QEMU+LinuxBIOS. I follow the steps in
http://www.linuxbios.org/Booting_Windows_using_LinuxBIOS, and do with
LinuxBIOSv3. However, in the documentation, I read:

.....
  Building LinuxBIOSv3

Now it is time to build linuxBIOSv3. You should first download it:

$ svn co svn://linuxbios.org/repository/LinuxBIOSv3
$ cd LinuxBIOSv3/util
$ svn co svn://linuxbios.org/repos/trunk/LinuxBIOSv2/util/ADLO
$ Apply patch that puts ADLO into LinuxBIOSv3
$ make menuconfig

....


I just dont see how to "apply the patch to put ADLO into LinuxBIOSv3".
ADLO was checked out from SVN, but it is a directory, so how can we
"apply patch ...." as in the instructions?

Thanks,
Jun

      Hmm... I managed to do like this:

- Compile ADLO separately, then I have a file named "payload"
- In LinuxBIOSv3, I run "make menuconfig", then specify the path of
payload option to the above "payload".
- Save options, quit and compile.

As a result, I have build/bios.bin, and I overwrites this file onto
the original bios.bin of my QEMU.

Then, I run QEMU with my Linux image. It works, and I can login to my
Linux QEMU.

Now, the problem is that I am not sure if my Linux on QEMU really uses
LinuxBIOS. How can I confirm that? "dmesg" doesnt seem to return
anything special to me.

Thank you,
Jun

No need to overwrite. Just use the '-L build' command line option for
QEMU and it will use the bios.bin in the build/ directory instead of
the normal one.

Use the '-serial stdio' command line option with QEMU, that will
print a "LinuxBIOS starting..." or similar message if it's really
LinuxBIOS.
