This worked for me on a 2513: First you have to make the router run an image other than that in FLASH. The router has to boot in RxBoot mode (small IOS image with a small set of commands). While in RxBoot mode, the router can download the new IOS. You have to boot into RxBoot mode, then you can deal with the IOS.
#conf term #config-reg 0x2101 (This tells it to boot from RxBoot mode) #^Z If you do a show ver, it should display 0x2101 as the register number for the next boot. Reload the router and answer "yes" or hit "enter" to confirm for the modify question. #reload (your telnet session will be lost, but after a few minutes, you can telnet back) #copy tftp flash (if you are using a telnet server) #config term #config-register 0x2102 (to put the register back to normal boot mode) #^Z At this point, you may want to reload the router again to make sure it boots OK. I hope this helps. Craig. ----- Original Message ----- From: Mark Shickell To: Sent: Tuesday, October 30, 2001 8:28 AM Subject: Re: AARRGGHH!!! Flash on a 2500!
