Hi All,

Current IOS: c2800nm-advsecurityk9-mz.124-15.T1.bin
New IOS: c2800nm-advsecurityk9-mz.151-4.M10.bin
My Current Rommon Version on Router is ROM: System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1)
do i need an upgrade to ROMMON Image befor the IOS Upgrade or this ROMMON would support my IOS. Also the LAtest version of Rommon Available for the Router is C2800NM_RM2.srec.124-13r.T11

Its ram would be your issue there do you have 512 / 128 for the new image on your current router, it looks as if the last image runs on a lot less 256 / 64. These 15 images require more hardware
if you dont have enough ram/flash it wont load for you

Hey you dont have enough dram to run that version IOS -------247808K/14336K this is basically 256 when added together it shopuld be 512 if you want to run v15
Edit: like Cisco CISCO2951/K9 (revision 1.1) with 483328K/40960K bytes of memory. =512
