NAME
     dnvr - display nonvolatile RAM

SYNOPSIS
     dnvr begin_offset [end_offset | l length]

AVAILABILITY
     This command is available only on RC6380 systems.

DESCRIPTION
     dnvr is a PROM monitor or standalone shell (sash(1M)) com-
     mand that allows you to display the contents of nonvolatile
     RAM, (NVRAM). All numbers are in hexadecimal byte format.
     You can omit 0x from the address; for example, you can use
     0400 instead of 0x400.

     The arguments for this command are as follows:

     begin_offset  Address at which to start displaying data,
                   expressed as a relative offset from the NVRAM
                   mapped-starting address (0xBE02C003). The
                   value must be hexadecimal.  For example, a
                   begin_offset of 010 is mapped-address
                   0xBE02C013. Using the offset eliminates the
                   need for remembering the mapped address.

     end_offset | l length
                   Specify either end_offset to indicate the last
                   address at which data is to be displayed or
                   use l length to specify the number of bytes.
                   If both are omitted, the command starts at
                   begin_offset and displays the next 128 bytes.

EXAMPLES
     Example 1: Dump NVRAM only from offset addresses 600 to 610
     by entering the following command:

          dnvr 600 610

     A display similar to the following appears:

                0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
          0600  03 01 03 02 03 01 03 01 00 00 14 00 00 00 00 00
          0610  00

     Example 2: Dump 20 NVRAM bytes starting at an offset of 600
     by entering the following command:

          dnvr 600 l 20

     A display similar to the following appears:
