Hi list!
Yes, I know how much RAM costs today (150NIS/128MB), but this is a matter
of principal (and the everpresent possibility of learning something new)
I have a buggy 64 Meg chip that works, but is broken at some memory
locations. No, it's not under warranty.
I know that in my good ol' DOS days, you could exclude certain memory
ranges from being used by passing parameters to HIMEM.SYS (or
emm386.exe? I really can't remember). You could find the addresses
of the buggy locations using apps like Norton Utilities for DOS.
Now I have this here chip, and a linux box I'd like to stick it in.
1. Is there any proggie for ANY os that can find the problematic addresses
on the DIMM, or do I have to write it myself?
2. Is there a way to ask the linux kernel nicely not to use these
ranges? (boot-time parameters, some special kernel driver, code tweaks,
etc.)
Thanks a bunch
