We have a 1841 router running an ipbase IOS. We need to upgrade it to a spservice IOS.
The ipbase IOS is 13.2 MB (13925828 bytes)
the spservice IOS is 18.4 MB (19 293 798 bytes)
here is the current show flash

so i think the new IOS might just fit since it is only 5MB bigger than the current IOS and there is about 10MB of free space... i'm doing this remotely so i need to make sure i get it right the first time... so do you guys think it will fit if i erase the old IOS first?

It should fit, but you needn't worry about getting it right firat time, as the router runs the IOS from DRAM - you can safely delete the IOS, try installing the new one then put the old one back as long as the router does not reload while you are doing it.
I am not sure if you need to squeeze the flash on an 1800 after deletion - some router deleting a file only flags it as deleted so you need to squeeze the flash to actually get the space back.

This is a good point. But the 1841 does not require a squeeze. When you delete a file on the 1841 the space is immediately available.

Thanks for the correction - I was not sure so thought it better to mention that it may be needed than have Luca panic whe he deletes a file and still only has a few meg available.
