I download A2 Bootable ISO CD-Image: A2CD.zip (77 MB)  from http://www.a2.ethz.ch/downloads/A2CD.zip, then I unzip and mount this ISO image on Ubuntu12.04,
sudo mount -t iso9660 -o loop  A2.iso /mnt/cdrom/

ls -a /mnt/cdrom/
but there is no file in the folder.

df -k
Filesystem     1K-blocks      Used Available Use% Mounted on
...
/dev/loop0        150046    150046         0 100% /mnt/cdrom

I use 7z to open the ISO file on Windows7, only one folder

It's because ISO image contains AosFS file system that known only for A2 itself. It's normal. You can inspect this file system content after mounting the disk in A2 environment.

Thanks for reply.

A2 can not boot on my laptop HP4321s (Intel Core i5-430M), black screen, nothing output.
Dose A2 support 64bit systems? In the rerequirements(http://www.a2.ethz.ch/requirements.html), it says "System: Intel 32-bit architecture PC. SMP and Hyperthreading supported.",  dose it mean that A2  can only run on older PCs?

Regards

to debug black screens, you have to set up low level tracing, see http://www.ocp.inf.ethz.ch/wiki/Documentation/Installation#toc13, maybe even serial tracing.

not really, but neither this page http://www.a2.ethz.ch/requirements.html nor this one http://www.ocp.inf.ethz.ch/wiki/Documentation/HardwareCompatibility are up to date. The group at ETHZ is very small and the documentation lags behind the actual state.

I created a Virtualbox VM according to the instructions given in the Builds section of OCP http://www.ocp.inf.ethz.ch/wiki/Development/Builds and it runs nicely in a 64bit virtual box.

You might try a newer CD-image from here: ftp://ftp.lrz.de/transfer/BlueBottle-A2/.
