Technologic Systems has upgraded the firmware for its quick-booting single-board computer (SBC) to make it boot even quicker.

To break the one-second boot barrier, Technologic improved the TS-7800's bootup firmware by implementing kernel simplifications, reducing the Busybox filesystem, and improving the LinuxRC initialization script, says the company. The board boots to a minimal kernel, and then loads an initial RAM disk that is said to provide access to full-Debian binaries and libraries. After 0.69 seconds, the user receives a Linux shell prompt and access to a Busybox filesystem, enabling network services and driver access to most of the SBC's hardware. The initialization process is then completed in the background in under two seconds.
