Hi there

Unfortunately, I have switched off my 803 while a file was sent to the router to configure it. After switching on, I got a different prompt (boot# ) and it doesn't change to the well-known router-prompt. What can I do to get back the usual configuration environment?

thanks
Simon
 
sm1981 you just entered a world of pain :)
Nah seriously I got myself into the same situation and had to work hard to overcome it.

Most of what you need is in this article -
IMPORTANT! Do NOT set your console baud rate greater than 9600 or you'll get a load of garbage characters on the screen and you won't be able to sort your problem.

You'll need a tftp program on your computer and the IOS image file.

3COM have a free tftp server available for download from this mirror:-

As for the IOS image you SHOULD have that on one of your documentation cd's although I never found mine and had to use other methods for obtaining it.

Good luck, have fun!
 
Simon,
The are two reasons why your router will boot into "boot#" mode:
1. No IOS located on the flash.
2. You config-register setting is configured to boot into "boot#" mode.

Before you go replacing your IOS file, check to see if your IOS is still on the flash. Do a "sh flash". If the IOS file is still there, then check your config-register setting. Do a "sh ver". The boot modes are:

0x2102 normal boot mode, loads startup file from NVRAM
0x2142 bypass NVRAM startup file
0x2101 boots into ROM "boot#" mode

If your config-register is set to 0x2101, then simply change the register setting.
Router(boot)#en
Router(boot)conf t
Router(boot)config-register 0x2102

If the file you were transferring at the time was the IOS, then its probably not there on the flash. Hence follow CtJackal's tips for IOS recovery.

Thanks for your help.

In fact, the IOS-File is gone and only the TinyROM is still existing. So, I guess, I need a new IOS image file. But where do I get one without being a cisco contract partner?
