I see. In general there's no way to discover that revision number from any of the information presented by the Sun Ray firmware. The -NN may change to address an issue that the firmware doesn't know about or care about, so there's no corresponding firmware change and therefore no change in the version strings reported by the firmware. For instance, the firmware wouldn't know or care about a VGA output analogue circuit change or a power supply replacement, whereas either of those events would cause the -NN to roll. Once in a while there'll be a hardware change that does require a matching firmware change, and in that case the firmware update will bring with it a new 'boot" version string. But the boot version string can also change because of a firmware update that is not tied to a hardware change. For instance, the update might deliver a bugfix or a new feature.
> "boot" indicates the original factory-loaded firmware version. Based on the "boot" values I have looked at I got the impression that this was hardwired (i.e. on a regular chip with no way of flashing it). Right? Wrong?
The "boot" firmware resides in FLASH, so in theory it could be overwritten, but as a matter of policy we never overwrite it. So in practice the "boot" string tells you the upper bound on the age of the unit. OttoM. __ ottomeister Disclaimer: These are my opinions.
