The last digit in your config register needs to be changed from a 2 to a 1.
i.e. 0x2102 to 0x2101
This can be done in config mode with the command "conf reg 0x2101" then
reload the router. It is not necessary to save this config when asked.
After the router reloads, you will notice the prompt will say <boot>
You can then copy your flash from the tftp server.
After the copy is complete, change the configs register back to 0x2102 and
reload again. Again, it is not necessary to save the config when asked.
IOS upgrade complete.

Subject: IOS Upgrade problem
Hi group,
I'm trying to upgrade from ios 12.0 to 12.1 on a 2501 with 16 mb flash. The
router to be upgraded also has version 11.0 bootstrap. The flash isn't
partitioned and the version of ios I'm trying to copy is running fine on
another 2501. I've tried copying the ios from both a PC running Cisco's
TFTP
server s/w as well as another 2501 configured as a TFTP server. It doesn't
work in either case.
I go through the tftp process but shortly after it starts, it fails. ( I
can
ping the tftp server just fine.)
I also noticed that with sho version, it says, 16384k bytes of processor
board
system flash (read only)
On some of my other 2501's, it says, (read/write) instead of (read only).
Could this be the problem? And, how do I change the flash from (read only)
to
(read/write)?
Thanks in advance, Jim
