Subject: how to tell linux (on x86) to ignore 1M or memory
Date: Thu, 19 Apr 2007 10:18:04 -0400	[thread overview]
Message-ID: <20070419141804.GO32620@jukie.net> (raw)

I need to preserve some state from the bios before entering protected
mode.  For now I want to copy it into some ram accessible by real-mode,
say the last megabyte visible in real-mode.

What's the easiest way to have linux ignore the megabyte starting at 15M?

Cheers,
-Bart
