gunzip the image, then dd if=astlinux-XXX.img of=/dev/sdX where sdX is your compact flash card).Astlinux supports two methods of persistent storage. You must use unionfs for some settings (such as passwords and changes to the root system), but you can optionally use an additional 'keydisk' partition. The 'keydisk' contains key information about your system such as the Asterisk configuration files, system settings and voicemail messages. Using a single unionfs partition contains all persistent information and is recommended for new installations.

Please be sure that you really use https (http will NOT work).

The “System is Rebooting…” will disappear when the reboot is complete, then click Finish, after a short delay the system will reboot once again.
Note: Since reboot times can vary, your browser may fail to automatically reload, don't worry, wait a minute and manually reload your browser to continue.
Normally you will not see the screen below, your browser should be redirected to the Status page, but if you reload the browser to /admin/setup.php after a successful installation, you will see the screen below. If so, click Continue, to view the Status page.
You can confirm that the setup was successful by logging into your pbx.
https://pbx.local (pbx.local is the IP address of your PBX).
You will get the following screen. (Note: This is only part of the full screen.)
The /dev/hda1 partition is your original partition created by installing the Astlinux-XXX.img. /dev/hda2 is the combined keydisk + UnionFS partition. If you selected seperate partitions, the UnionFS partition would be /dev/hda2 while the key disk would be /dev/hda3.
