Testing the downgrade by removing the 128 meg chip and replacing with 64 meg the firewall does become "unusable" - the POST seems to run correctly based on the audible beeps, but the boot cycle never never completes and a prompt is not received at the console. Replacing the memory with the 128 meg DIMM resolves the problem.</P><P></P><P>Any advice on downgrading the memory and the steps required to resolve the issue?</P><P></P><P>Thanks.....</P> Fri, 21 Feb 2020 06:10:00 GMT https://community.cisco.com/t5/network-security/downgrade-pix-memory/m-p/82147#M627487 csmith 2020-02-21T06:10:00Z Re: Downgrade Pix Memory https://community.cisco.com/t5/network-security/downgrade-pix-memory/m-p/82148#M627488 <HTML><HEAD></HEAD><BODY><P>Sorry this took so long to answer.</P><P>Basically this PIX is now unusable, and you'll have to contact Cisco to get a replacement for it.
