Three Easy Steps to Merging the Code

Here is the program for merging Nachos/486 into existing code:

1. Copy machine/timer.cc, machine/sysdep.h, and machine/sysdep.cc to the machine/ subdirectory. (Backup those files first.)

2. Merge the changes from the Nachos/486 files threads/thread.h, threads/main.cc, threads/system.cc, threads/utility.h, and threads/utility.cc into the corresponding files in the threads/ directory.

3. Copy the Nachos/486 directory, nachos486/ into the nachos tree.
