Troubleshooting Entering Commands at the Boot Prompt
B - 3
B.4 Entering Commands at the Boot Prompt
If the Boot prompt appears on the serial console instead of the Local prompt, one of two things
may be wrong. Either the MSS does not have enough information to boot, or the network or flash
boot has failed. If pressing the Return key does not display a prompt, press any other key. The
Boot prompt should appear.
If the MSS does not have enough information to boot, or the network or flash boot has failed, it
will print a message to the console and wait ten seconds for serial port activity. If it detects serial
port activity, it will continue booting provided the flash is good. However, if the user presses a key
during that ten second time period, the MSS will display the Boot prompt.
NOTE: If the message “Will attempt another download in x minutes” is displayed, press any key for
the Boot prompt.
A series of commands called Boot Configuration Program (BCP) commands can be entered at the
Boot prompt to configure the MSS. These commands are a subset of the entire MSS command
set.For example, a typical TCP/IP configuration might use the following commands:
Figure B-1: BCP Command Examples
These commands set the MSS’s address, the software loadfile, and the loadhost’s IP address (as
well as that of a backup loadhost). The server then reboots using the Init 451 command and will
attempt to load the file MSS.SYS from the host at 192.0.1.188.
The following commands are available from within the Boot Configuration Program.
B.4.1 HELP
Displays a one-page summary of available commands and what they do.
B.4.2 INIT 451
Reboots the MSS after it has been configured. If the MSS can find and load the specified software
loadfile, it will restart itself with full functionality. If the loadfile is not found, the server will
attempt to reload continuously. If there is an error, or if the console’s <Return> key is pressed, the
MSS will re-enter the Boot Configuration Program.
