I have been able to install RouterOS 3.38.3 onto a SBC. I am trying to add an included Ethernet driver ibg, but following all the instructions, I am getting nowhere. I have tried entering folder and entering in command and entered full command such as /driver add name ? or /driver>add name ?. At the driver folder when I enter ? I only get find get and print, when I enter add I get the message bad command name. Also is there a way to pause the scroll, when I enter ?, the lost of commands scroll off the screen so I can only see the last few command.
Installing your own drivers is not possible in RouterOS. I assume you are trying to install an x86 version of RouterOS. You have only two options here- either use a compatible hardware, or install CHR under a hypervisor of choice.
