Did you get your desk upgraded?
I have the file downloaded.
Download the software http://www.flyingpig.com/phpscripts/fullboar/recovery.php
You will need the serial number.
Burn an ISO with the downloaded file.
Power on the Full Boar with the CD in the drive.
When asked hit any key on an external keyboard.
Choose Full Install when asked.
This will delete ALL show files on your desk so back them up to external media before performing the install.
Ok downloaded the FB system restore R1.8.1 on to a PC
Now burn an ISO.
On PC how is that best done?
I tried this with a disk burner and just got the same file on a CD.
Tried it in the FB and it does not really see it.
Burning this incorrectly?
