From 9d35c6ade54c05754a1cac99df5c9a8ce6252bbe Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Wed, 4 Oct 2023 09:38:05 +0100 Subject: q800: add alias for MacOS toolbox ROM at 0x40000000 According to the Apple Quadra 800 Developer Note document, the Quadra 800 ROM consists of 2 ROM code sections based at offsets 0x0 and 0x800000. A/UX attempts to access the toolbox ROM at the lower offset during startup, so provide a memory alias to allow the access to succeed.
