Name:         040 VM Update
Version:      1.0
Released:     11-Aug-94
Description:  This extension fixes a problem (reported only on the Macintosh LC 575 and Macintosh LC 630) where 040 based systems can hang when running with the 040 processor caches turned on, VM turned on and the system software is copying data from one part of system memory to another using the 040 move16 instruction.  The fix involves using a different data blockmove routine that does not use move16 instructions.
