Can you elaborate on this? Hasn't Cisco IOS at various times run on MIPS and X86 processors?
- kragen 6y agoUnfortunately I'm just reporting secondhand rumors from people who worked at cisco, and I probably should have made that clear. So I don't know how IOS works at the machine-instruction level, just the command line.
- icedchai 6y agoThe original Cisco IOS ran on 68000 series processors which lacked an MMU. Even the later 68K models used an "embedded" version of a processor which did not have an MMU. For example, the Cisco 2500 used a 680EC30. Regular 68030s had MMUs, but the "EC" model did not. Later versions did run on MIPS though.
