- The 68040.library is a collection of code, support routines, and patches
- to the system that gives you the most out of your 68040. In addition to
- the 68881/68882 emulation code, 68040.library also contains a number of
- patches to the system to help out programs that do not call CacheClearU()
- at certain times. It also adds code to do the CachePreDMA/PostDMA() routines
- for dealing with CopyBack caches. It also sets up the MMU (if you have
- a 68040 or 68LC040) to map the address space such that bus errors will
- be less likely and such that Zorro-III I/O cards are marked with the
- right cache settings. There are a number of other things it does too.
-
- The reason for being a library is that I hope to add some LVOs to it at
- some point but the main reason is that as a .library it is easy to use as
- a system extension. That is, SetPatch just needs to open the library since
- the library will only open on a 68040 system. This makes the 68040.library
- disk loadable and easy to install without having different startup sequences
- or a 50K SetPatch program.
