This section covers boot options that can be set from the Firmware bootstrap menus. For information about file transfer and file management, refer to Networking Multilayer Ethernet Switch Installation and Planning Guide.
The purpose of the bootstrap firmware is to provide a Power On Self Test (POST) for the IBM 8371 processor card and to boot from the active operating system image stored in the FLASH memory.
Two operating system images are stored in system FLASH. The active boot image is selected by using the Configuration boot command. The active image selected using the boot command is used to boot the device. You can select the backup boot image or the Ethernet service port using commands available from the firmware bootstrap menus. See "Select Boot Device".
Before booting the device, note that:
To display the bootstrap main menu, power on the 8371, and press Ctrl-C on the terminal keyboard after one second.
Important: To access the Firmware prompt, you must stop the 8371 boot. To stop it, you must have a TTY console directly attached to the serial port. When the 8371 starts its boot sequence, press Ctrl-C from the console to interrupt the boot sequence.
From the Main Menu panel shown in Figure 3, you can select one of five services. The following sections explain these services and provide instructions for going through the associated panels:

|---|---|
| Display Error Log | Displays the self-test error log. See "Self-test Error Codes" for a listing and description of the error codes. |
| Clear Error Log | Clears the self-test error log. |
| Return to Bootstrap Main Menu | Displays main menu as shown in Figure 3. |
| Issue Reset | Resets the hardware. |
The following options are available from the Select Boot Mode menu:

| Function | Description |
|---|---|
| Normal Boot | Boot and execute operating environment. |
| Service Boot | Boot and execute service environment. |
| Bootstrap Menu | Display Bootstrap menu. Does not cause a boot. |
| Return to Main Menu | Displays main menu as shown in Figure 3. |
| Issue Reset | Resets the hardware. |
Once selected, the IBM 8371 will stay in the selected boot mode until a different mode is selected from this menu.
The following options are available from the Select Post Mode menu:

Table 4 contains a description of the Boot Mode menu functions.
Table 4. Select POST Mode Functions
| Function | Description |
|---|---|
| Set POST on (next reset only) | This option causes a more extensive self-test (POST) to be executed the next time the device is reset or powered on. Once the extended POST executes successfully, the normal, short POST will be executed on successive executions of POST. |
| Set POST off | Indicates that the normal, short POST will be executed. |
| Return to Bootstrap Main Menu | Displays main menu as shown in Figure 3. |
| Issue Reset | Resets the hardware. |
The following options are available from the Select Boot Device menu:

Table 5 contains a description of the Boot Device menu
functions.
Table 5. Select Boot Device Functions
| Function | Description |
|---|---|
| Boot from active Flash bank (normal boot) | Two copies of the operational code exist in FLASH. The active image is the image from which a normal boot occurs. |
| Boot from backup Flash bank (backup boot) | Indicates that the next boot only of the IBM 8371 is to be from the
alternate (backup) image. The alternate image is intended for recovery
when the active image has become corrupted and cannot be booted.
Once the IBM 8371 has been booted, the boot device will be automatically reset to the active Flash bank. |
| Boot from Ethernet service port | Selects TFTP boot from an Ethernet server with IP address
10.1.2.3 the next time the IBM 8371 is booted.
The filename on the server must be os8371.ld. The file must be located in the TFTP server directory on the workstation. On an AIX workstation, the default directory is /tftpboot. TFTP applications on Windows workstations allow you to designate the TFTP directory. If you do not have a TFTP application, you can download one from the Web at www.alphaWorks.ibm.com/formula/tftp. Once the IBM 8371 has been booted, the boot device will be automatically reset to the active Flash bank. |
| ZMODEM boot via RS 232 service port | Selects ZMODEM boot from a workstation attached to the RS 232 service
port the next time the IBM 8371 is booted. The boot image must be
stored on the workstation and the workstation must support ZMODEM
sendfile. The file transfer rate is fixed at 19.2 Kbps and the
image download will take about 36 minutes.
This function supports boot image recovery if both images in the FLASH memory are corrupted and TFTP boot via the Ethernet service port is not possible. Once the IBM 8371 has been booted, the boot device will be automatically reset to the active Flash bank. |
| Return to Main Menu | Displays main menu as shown in Figure 3. |
| Issue Reset | Resets the hardware. |
This function resets the IBM 8371 and executes the selected option. This reset causes a POST to execute.
The following error codes are displayed on the
service terminal and logged in the self-test error log when self-test detects
a hardware failure. Select option 1 on the Bootstrap Utility Menu (see "Bootstrap Utilities") to display the error log.
