Arthur,
2500 routers execute the IOS from Flash rather than load it into DRAM.
Therefore, the flash is read-only.
Solution: don't boot from flash ... "config t", "config-reg 0x2141",
"reload". Now "show version" indicates flash partitions are read-write.
Add an IP address to E0 or S0, and copy new IOS from tftp server. If server
is not on same network, you'll need ip default-gateway X.X.X.X on your 2514.
After you've got the new IOS, write-erase the NVRAM so you start with a
clean startup-config (i.e., no partition flash statements), set the
config-reg back to 0x2102, and reload.
HTH, Kym
