i'm looking for a method to dump the contents of the nvram of my two
netbsd boxes (both 4c) to a file and eventually restore them later.
In sunos you can do something like
dd if=/dev/eeprom of=myfile bs=1 count=2048 to read the nvram
dd if=myfile of=/dev/eeprom bs=1 count=2048 to restore the nvram
In netbsd /dev/eeprom is there but the command leads to a "device not
configured" error. Is there any device associated to the nvram?
If not directly, is the nvram accessible via /dev/kmem ? if Yes, how?
related question: is there any way to set ethernet address and hostid
in a running kernel (again possible with adb under sunos)?
Thanks for any hint
