   |  Hi Martin,
 
 I'm not Martin, but ...
 
   |  May the system recognise automatically the new board (XVR-100 instead
   |  XVR-1200) at the boot, or there is a sort of Solaris "boot -r" to reconfig
   |  the new devices, or it's better to reinstall NetBSD from scratch??
 
 Assuming you are still running the GENERIC kernel (you haven't configured,
 built, installed, and booted, a modified version) then all you need to do
 is reboot - the kernel looks for hardware that is installed every time it
 boots (and for some, that can be hot plugged, whenever it is plugged in.)
 
 Even if you have a modified kernel, it would only matter if you had
 removed the driver for new device, and either you don't have support
 for modules or the driver has not been modularised - since in this case
 the driver for your replacement board is likely the same one as you hoped
 would work with the unsupported board, it is unlikely you would have
 removed it, even in a custom kernel - so even there just a reboot should
 work.
 
 No special boot sequence is required, and there is certainly no benefit
 to installing (the same system version) again.
