Re: RB850Gx2 vs RB450Gx4

So, now that you have "corrupted" ( :lol: ) the 400-series with a non-MIPSBE CPU, you are faced with the challenge of efficiently communicating this on the ROS download page. Right now, if I am the proud owner of a new RB450Gx4, and I go to this page, I'm being told I need to download the MIPSBE pac...

Re: OpenWrt for ARM-based RB1100AHx4

There is no MetaROUTER for RouterOS ARM platforms. Do you see a "/metarouter" tree on the RouterOS CLI for your AHx4, or a "MetaROUTER" config option within Winbox for this model? Thought not.
