In make menuconfig, under: Device Drivers → Graphics support → Console display driver support (700) Scrollback Buffer Size (in KB)
I think the default was 64 but I like a big scrollback buffer. As you see I set 700 but really didn't have much of an idea what that would be in lines. Can any one offer a close guestimate what 700 kb would be in lines. That is pretty close to 1 mb isn't it?... but still what is that in lines? I'm guessing 1 MB might be around 10,000 lines. Is that even roughly close... if so I probably should have went higher.
