Hello All, I have been unable to flash a C2501 running this (very old) version of IOS & the IOS even appears to be in-apropriate for the device . But it is for the correct cpu . PS: please point me at the Cisco maillist . I'd rather post this there . But seeing as how little I have been able to get out of Cisco on (some) matters I thought it better to ask those whom probably have run IOS code such as this . Tia, JimL I have attempted : Silverdale#copy tftp flash Copy aborted. Flash address space cannot be written to. Full copy of the startup messages & some other info that may / mat not help .
