Hello.

On our TS-7300's we have found the hw clock drift to be too large to 
support our objectives.  To correct this we have replaced the on-board 
hw clocks with another.  After replacement, on boot, an error message 
is displayed indicating the hw clock cannot be accessed using any known 
methods.  If you manually run the "hwclock" utility with the debug 
option, it says that /dev/rtc cannot be opened because it doesn't 
exist. Upon examination, /dev/rtc does not exist.

What is the mechanism whereby the hw clock is discovered and when 
is /dev/rtc created?  Is there something we need to do to get the OS to 
recognize the new clock?

Thanks,
G.
