Cisco ROM Monitor Upgrade Guide for the PRE3
This document contains procedures for a Cisco ROM Monitor software download.
This document contains the following sections:
ROMMON Version 1.0.1 works with Cisco IOS software Releases12.2(31)SB12, 12.2(33)SB, and later.
ROMMON Version 1.0.1 is supported on Cisco 10000 series router.
This section documents the caveats that can be resolved by installing ROMMON Version 1.0.1.
The following caveats can be resolved by upgrading to ROMMON Version 1.0.1:
The ROMMON banner required updating from 2006 to 2007. This has been fixed.
ROMMON used the first executable image in boot flash memory as a boot loader when the boot xyz command was executed, where xyz is not a known file system. However, if the first executable image is a full Cisco IOS software image, the boot failed. This has been fixed.
When the Cisco IOS image was reloaded, the Resetting string became truncated. This has been fixed.
Performing a Performance Routing Engine 3 Upgrade
The following sections explain how to perform a Performance Routing Engine 3 (PRE3) ROMMON and EBOOT image upgrade:
Upgrading the PRE3 ROMMON Image
Upgrade your PRE3 board ROM (ROM1 and ROM2) to the new ROMMON MCE_RM.srec.1.1 firmware, which you can download from:
The following steps show how to upgrade the PRE3 ROMMON:
Step 1 If the ROMMON image is running on the router, boot the eboot image from the boot flash memory. However, if either Cisco IOS or eboot images are running on the router, you can enter the rom command to see which ROMMON is being used. If rom0 (golden rom) is being used, you can upgrade the router to either the rom1 or rom2 image. If either of the rom1 or rom2 image is being used, you can upgrade the one not being used currently. In the following example, rom0 is being used.router# romROM IMAGE STATUS--- ----- ------ROM G (Golden ROM) DEFAULT & IN USEROM 1 (Field Upgradable) FIRST_RUNROM 2 (Field Upgradable) FIRST_RUNIn ROM 0, ROMMON version:System Bootstrap, Version 12.2(20060320:155403) [fyang-rom_1_0 101], DEVELOPMENT SOFTWARE Copyright (c) 1994-2005 by cisco Systems, Inc.In ROM 1, ROMMON not yet completely verified. The version info is not available.In ROM 2, ROMMON not yet completely verified. The version info is not available.
Step 2 To upgrade rom1, enter upgrade rom rom1 file tftp://<tftp_server_ip>/<tftp_dir>/MCE_RM.srec.1.1. You can also copy the ROMMON image to the boot flash memory and upgrade the image from boot flash by using the upgrade rom rom1 file bootflash:MCE_RM.srec.1.1 command.
Step 3 During the upgrade, enter yes to all questions, as shown in the following example:router# upgrade rom rom1 file tftp://<tftp_server_ip>/<tftp_dir>/MCE_RM.srec.1.1Loading pre3/images/MCE_RM.srec.1.1 from 22.214.171.124 (viaFastEthernet0/0/0):!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!![OK - 882211 bytes]ROM 1 update in progressErasing (this may take a while)...Programming...CCCCCCCCCCCCCDo you want to verify this image (may take a few minutes)? [yes/no]:yes Verifying ROM 1Reading from ROM 1...vvvvvvvDoneComparing with the source file...PassedSet this ROMMON image as the default (will take effect on next reload)?[yes/no]: yes
Step 4 Reload the router.
Step 5 To complete the ROMMON upgrade, boot the eboot and Cisco IOS images again. When the eboot and Cisco IOS images boot successfully, the new ROMMON becomes the default. To upgrade another ROMMON, go to Step 2 and repeat the procedure.router# romROM IMAGE STATUS--- ----- ------ROM G (Golden ROM)ROM 1 (Field Upgradable) APPROVED DEFAULT & IN USEROM 2 (Field Upgradable) APPROVEDIn ROM G, ROMMON version is inaccessible when executing from either ROM 1 or ROM 2.In ROM 1, ROMMON version:System Bootstrap, Version 12.2(20060428:204330) [fyang-rom-1_1 102], DEVELOPMENT SOFTWARE Copyright (c) 1994-2006 by cisco Systems, Inc.In ROM 2, ROMMON version:System Bootstrap, Version 12.2(20060428:204330) [fyang-rom-1_1 102], DEVELOPMENT SOFTWARE Copyright (c) 1994-2006 by cisco Systems, Inc.
Upgrading the EBOOT Image
To obtain the new eboot image, copy and paste the following link in your Web browser, and then download the image:
The following steps show the upgrade procedure:
Step 1 Ensure that the new eboot image is the only eboot image in boot flash memory. After you upload the latest image with a new filename, delete the current eboot image. Or, you can also overwrite the current eboot image during the copy tftp bootflash command using the same filename, as shown in the following example:router# dir bootflash:Directory of bootflash:/1 -rw- 3291512 May 12 2006 11:52:28 -05:00 c10k3-eboot-mz127913984 bytes total (74493952 bytes free)router# copy tftp bootflash:Address or name of remote host ? <tftp_server_ip_address>Source filename ? <tftp_dir>/c10k3-eboot-mz.20060524Destination filename [c10k3-eboot-mz.20060524]? c10k3-eboot-mz%Warning:There is a file already existing with this nameDo you want to over write?

Step 2 To confirm that the new eboot works, configure the router for a tftp boot as shown in the following example:router# sho run | incl bootboot-start-markerboot system bootflash:c10k3-p11-mz.122-31.4.32.SBboot-end-markerrouter# conf tEnter configuration commands, one per line.
