Cisco Pix 525 will not accept new OS, continues to boot into previous pix version
Posted on 2008-10-28
I have recently inherited a pix 525, and when I attempt to load pix os 8 onto the unit, it does not accept it. I boot to ROMON, then i tftp the new config over and the reload the unit. I also use the password reset steps to flush the old password out...the box does not accept the new os and when I reload the unit it boots to the old os and asks for a username and password. I just want to factory default the unit...I've done this many times on 515's 506's and even ASA's without issue...I seem to recall reading that others have expierenced simialar issues with these, any ideas on what I might be missing or should try to factory default this unit?
