The fail-safe TS-7800 image serves as a demonstration of how to set up a TS-7800 so that it can run Debian and automatically restore itself in the event of filesystem corruption. This image assumes the TS-7800 has the RTC option and it uses one byte of data in the RTC's extra RAM to store the boot status. Whenever it boots and the boot status is not normal, it performs a full restore of the root partition. To create a fail-safe SD card, download these files to your Linux PC: b0f03abebb29d590b9008d507f22276d failsafe-skeleton.dd.bz2 2357226276189964321672dc2ca89ac2 failsafe.tar.gz c459bcc710803cab58c77e0905cb371c make-failsafe-sd.sh Then run, for example, './make-failsafe-sd.sh sdf' if your SD card appears as /dev/sdf. Any 2GB SD card should work with this image. Boot your TS-7800 with RTC from the resulting SD card. It will perform a fail-safe Debian boot. The changes from the standard image should be evident in /initrd/linuxrc-failsafe and in /etc/rcS.d/ and /etc/rc3.d/. This image is a demo only, it is intended as a starting point for customers that need a fail-safe system. Contact Technologic Systems if you have any questions about this image.
