A daft (but frustrating) problem....
I am trying to upgrade the IOS on an 1841 router so I can use it for VPN. At the moment "sh ver" outputs the below capacity:
191K bytes of NVRAM.
31360K bytes of ATA CompactFlash (Read/Write)
The image size I'm trying to load on to the router is 24.3 MB on disk. On paper I have enough space available for this image but when I go through the process of copying it from the TFTP server - it complains of not having enough space available. Cisco's documentation (http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a00801fc986.shtml#intro) says it will prompt me to delete the exisiting image if space is an issue (i.e. not enough room for 2 images) but this doesn't happen - the copy just fails. Can anyone advise what I can do to overcome this issue? I have tried various sizes of image all within the scope of the space I have available but to no avail! any help will be much appreciated
Many thanks
Danny

Try to put in the PC card reader tha flash, and delete unnecessary files, and copy the new ios to flash, it is faster!

if you tftp the image from rommon> mode it will erase the existing image first so that there will be room.
Else just delete the existing image from enable mode router#delete flash:c18*   then tftp the new image, then reboot.
