Even if im not seeing some file/s on my dir flash: command i executed boot nevertheless.
rommon 15 > boot
lseek out of bounds
getdirent: lseek error
boot: cannot determine first file name on device "flash:"
So tried a network boot
rommon 16 > boot c2600-c-mz.123-23.bin 172.16.15.205
lseek out of bounds
getdirent: lseek error
an alternate boot helper program is not specified
(monitor variable "BOOTLDR" is not set)
and unable to determine first file in bootflash
loadprog: error - on file open
boot: cannot load "c2600-c-mz.123-23.bin 172.16.15.205"

Here's what i think. The first file dowload could be corrupted and it eats up the space on my flash.
My question is how can I reformat the flash so that I can redownload the IOS? And if in case that fails also, any other way i can recover this machine
Thanks,
Jon

I've tried the ios and the same proceedure on another router and even on the gns3, it works fine. Im thinking of reformatting the flash, but couldn't find the right procedure on a cisco 2620 router.
