i have a 2600 router, the configuration register was mistakenly changed to 0x2162 , but when i tried changing it to the default 0x2102, it will only changes to 0x2122. i tried all i could but it seems the 2 b4 the last will just not change to any value below 2.
what can be done to correct this and if nothing, what is the implication of leaving the confreg as 0x2122.

Leaving it a 0x2122 will not "hurt" the router, this means that bit 5 is turned on but Cisco no longer uses that bit so you shouldn't have to worry. However it doesn't make sense that you can't change the register config back to its default the following commands should change it:

get into enable mode

router# config t
Router(config)#config-register 0x2102
Router(config)#sh version
--after doing a show version,
the router will tell you what the register will be after the next
reload
Router(config)#reload

you should then be all set

well i did go thru the steps and 1) the "sh ver" ver command would only tell u that it would be 0x2122 at next reload.
the main issue is i cant copy the running config to startup config again . i guess its the config reg. setting
thanks again
