Hi, all,
I have a question. say I have 128M physical memory, but for some reason, I
don't want the kernel to use a little part of that memory, e.g. physical
address from 4M to 5M. is there a way to let the kernel to do something
like this? thanks in advance.
Alex

Look in the archives for a thread entitled 'broken memory chip -> software
fix?' that you JUST missed.

I think the badram kernel patches do just that. See
