Technologic Systems' TS-7800 ARM9 single-board computer already had quite a bit going for it with its promised 2-second Debian boot times, but the company's now gone and let loose a new firmware upgrade that cuts that down to under a second -- 0.69 seconds, to be exact. As you might expect, that time is helped considerably by being able to boot the OS (Debian Sarge, specifically) off of the board's 512MB of NAND flash, and in that 0.69 seconds you will only get a linux shell prompt and access to the Busybox file system but, still, it is an OS booted in 0.69 seconds
