- ;** MMU Configuration file **
- ;** **
- ;** this file is read on startup by the mmu.library and used to modify **
- ;** the pre-calculated or scanned MMU table **

-
-
- ; the current version of the MMU library knows six commands that can
- ; be used in this file:
- ; CLEARTTX clears all or parts of the transparent translation registers
- ; ADDMEM adds memory to the exec free list pool. BE WARNED, this command
- ; does NOT modify the MMU tables, this must be done by yourself
- ; SETCACHEMODE defines the MMU tables.
- ; DESCRIPTORCACHEINHIBIT defines whether the data cache should be disabled
- ; for the MMU descriptors. It's usually OFF meaning the cache will
- ; remain enabled. This is fine for the mmu.library, but certain
- ; hacks might require a ON argument here. Note that this means more
- ; work for the library.
- ; FOR executes a command only for a specific hardware expansion which is
- ; given by the manufacturer and product ID.
- ; CLEARMMU overrides the MMU configuration found by the library for selected
- ; parts of the configuration.
- ;
- ; All other commands are currently "external". The library will scan for
- ; these commands in "LIBS:mmu" and execute them on startup. These *are not*
- ; standard shell commands. They cannot be run from the shell, and shell
- ; commands cannot be started from this file.
- ;
-
-
- ClearTTx ;ignore all TTX registers if any. We don't need them.
- ;this will speed up the system for some machines.
-
- ; Remove the semicolon in the line below if you have to live with other MMU
- ; hacks that expect the MMU descriptors in non-cacheable memory. This is by
- ; default OFF, i.e. descriptors will be cachable.
- ; The library will work fine and will take all precautions for descriptors
- ; in the cache, but some third-party hacks might not.
-
- ;DescriptorCacheInhibit ON
-
-
- ; Remove the semicolon in the two lines below in case you encounter hangs or
- ; crashes with Zorro-II 16-Bit memory. It will disable caching for the Z-II
- ; area. Clearly, this is slower, but it will work, at least.
-
- ;SetCacheMode from 0x00200000 size 0x00800000 CacheInhibit NonSerial Imprecise
- ;ClearMMU Expansion
-
- ; The following lines are strictly speaking not necessary.
- ; They will change and optimize the caching mode for graphics boards,
- ; but it will also work without them.
- ;
- ; The Picasso96 software will also optimize the MMU caching mode itself
- ; and therefore makes the following completely superfluous.
- ; CyberGraphics does not take these steps and might profit from the
- ; following.
- ;
- ; To speedup booting, you may remove all the lines of the boards
- ; you do not own.
