installation file from the TFTP server.
• This process removes any existing software packages,
resets the configuration register to 0x2, and boots the RSP

using the TURBOBOOT variable takes some time. Do not
enter any commands until you are prompted to enter a

occurrence appears when the software is loaded into
memory. The second occurrence happens after the software
has been installed on the disk.

change the configuration register. To reset to EXEC mode,
select the boot type as 2 when prompted.

boot process instead of staying in ROM Monitor mode.
