Re: Configuration Register Question [7:30713]
I need to do more studying on this topic, so forgive me for asking, but why does the conf. reg change according to line console speed?? I thought the confreg was just a setting telling the router whare to boot from? Does it do more?

RE: configuration register
The "1" in the last nibble there indicates that you are booting to rommon e.g. http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500/2524/ boa/boamnt.htm#xtocid1109016 watch the word wrap. You will need to perform the "password recovery" procedure, and change the config register to 0x2102 If you are actually in the prompt rommon> you can easily issue the "o/r 0x2102" command, then the "I" command to reinitialize.

Com Subject: RE: Configuration Register and Netboot Failure Thanks for the 3COM URL, I am still perplex why my router is trying six time to netboot when I have nothing in flash and nothing in NVRAM. According to Cisco (Verbatim) the following should happen: *-*-*-* "If boot commands are in the configuration file, the router software processes each boot command in sequence until the process is successful or the end of the list is reached." LAC: Step 1: The router sees "boot system " commands. Boot commands ARE in the configuration file. The router software processes each boot command in sequence until the process is successful or the end of the list is reached. *-*-*-* "If the end of the list is reached without a file being successfully booted, the router will retry the netboot commands up to six times. . ." LAC: Step 2: The router reached the end of the boot system commands without being able to successfully load a system image. The router tries netboot commands for up to 6 times... *-*-*-* "unless the boot default ROM software if netboot fails bit (bit 13 of the virtual configuration register) is set. If bit 13 is set, the system boots the boot helper image found in boot Flash memory without any retries." LAC: Step 3: We're now told that if bit 13 IS set, the 6 netboot attempts WON'T be attempted. *-*-*-* LAC: This whole process hinges on the fact that boot system commands exist. If boot system commands DO NOT EXIST, the system MUST ATTEMPT TO NET BOOT. This happens whether or NOT bit 13 is set. This paragraph doesn't say ANYTHING about the boot process if boot system commands DO NOT EXIST. Put a "boot system" command in your startup config. Your netboot attempts will cease... (NO NETBOOT attempts will occur) LAC: Remember when I first started to correspond with you regarding boot issues - you wanted to know why a net boot wasn't being attempted on your router? I indicated that you had boot system commands set in your startup-config file. Once you erased your config, it attempted the netboot again. No boot system commands, netboot worked!

The meanings of the config register - Bit No. Hex Meaning 00-03 - 000F Boot Field Stay at bootstrap prompt 0001Boot system image on EPROM 0002 - 000F Specify default netboot filename - cisco-processor_name - where 2 Off On On On On Off So, 0x2102 = 2 - Boot from ROM if network boot fails 1 - Break command during boot puts router into ROMMON mode 02 - Default file name for a net boot is cisco2- depending on what machine you have. > >Can someone explain to me what I configuration register is and what it >is used for - it, of course, shows up on a show version command - I did >some looking around on CCO and all the information I found said to set >it when you upgrade the IOS to 0x2102 but I can't seem to find out what >it does or how it does it. > >Thanks!

Configuration Register
Title: Configuration Register Can someone explain to me what I configuration register is and what it is used for - it, of course, shows up on a show version command - I did some looking around on CCO and all the information I found said to set it when you upgrade the IOS to 0x2102 but I can't seem to find out what it does or how it does it.
