From 5702d0f742b2f462267bca147334f77a255bcc74 Mon Sep 17 00:00:00 2001 From: Zachary Amsden Date: Fri, 6 Jan 2006 00:11:51 -0800 Subject: [PATCH] [PATCH] x86: Pnp segments in segment h Move PnP BIOS segment definitions into segment.h; the segments are reserved here, so they might as well be defined here as well. Note I didn't do this for APM BIOS, as Macintosh and other systems use those values to emulate APM in some scary way I don't want to understand.
