Hello Experts,
We have a Cisco 2811 Router which boots into the Rommon mode. Here is the related logs and configs:
System Bootstrap, Version 12.4(1r) [hqluong 1r], RELEASE SOFTWARE (fc1) Copyright (c) 2005 by cisco Systems, Inc. Initializing memory for ECC . c2811 processor with 262144 Kbytes of main memory Main memory is configured to 64 bit mode with ECC enabled Readonly ROMMON initialized loadprog: error - on file open boot: cannot load "flash:c2800nm-advipservicesk9-mz.124-13a.bin" c2811 processor with 262144 Kbytes of main memory Main memory is configured to 64 bit mode with ECC enabled Readonly ROMMON initialized boot: cannot open "flash:" boot: cannot determine first executable file name on device "flash:" c2811 processor with 262144 Kbytes of main memory Main memory is configured to 64 bit mode with ECC enabled ------------------------------------------------------- rommon 2 > dev Devices in device table: id name flash: compact flash bootflash: boot flash eprom: eprom ------------------------------------------------------- rommon 6 > set PS1=rommon ! > FE_PORT=0 WARM_REBOOT=FALSE BOOT=flash:c2800nm-advipservicesk9-mz.124-13a.bin,12; RET_2_RTS=02:13:14 Pacific Tue Apr 26 2011 BSI=0 RET_2_RCALTS= RANDOM_NUM=365387326 ?=0
I tried reseating the external flash card and rebooting the device, but no luck. Can anyone please help me to resolve this problem?

The CF used is not "supported" by the router.

Hi,
c2800nm-advipservicesk9-mz.124-13a.bin is the only file you have on flash ?
how does 'show flash' looks like?

Does this mean that the Compact Flash might have gone bad?

No, it means the CF is not supported by the appliance. Get a different brand of CF and try again.
And I doubt someone has upgraded the Bootstrap of the router so this means booting the IOS from the USB won't work.
