Do you have a line in your config that starts "boot flash:"
If so, remove it.
Else, set the router to ignore the startup config:
Using the ROMmon confreg Utility, watch for the line enable "ignore system config info"? y/n [n]:
Answer Yes to this one only, then reboot.

Are you sure you have enough DRAM memory for the IOS version you have?

Hi,
once your router is up, you'll need to copy tftp flash. I think what is happening, and has happened to me is that it just uses the xmodem to boot from. You then need to copy the image to flash, and make the changes in the Config to reflect the image in the flash as stated above. that should do it.
regards,
Corey

Hi,
I just saw one thing the : is missing in the config, but
still it should read the first image in the flash.
Have you tried to format the flash first then xmodem the image or tftp the over?

Corey

oooops lmost forgot you might want to reset the Boot varible as well.
ASKER
when xmodeming the file over it has an option to erase flash first...i have done that
as far as formating the flash..How is that done
and
how do i reset the boot variable?

you use the command BOOT=[variable]
Sorry for formating the flash I was thinking about something else sorry.
But if all else has failed, I would saw your flash is defective. Just out of curiosity what is your config-register set at? 0x2102?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Looking into this abit more there was a bug in the Bootstrap earlier then the one you have. But you should clear the variables you currently have use the folowing:
rommon 1>unset MONRC
rommon 2>unset BOOT
rommon 3>sync
rommon 4>reset
rommon 1>unset MONRC
rommon 2>unset BOOT
rommon 3>sync
rommon 4>reset
Did you also follow the memory table set up for your 98MB Ram?
