;*************************************************************************
;** MMU Configuration file **
;** **
;** this file is read on startup by the mmu.library and used to modify **
;** the pre-calculated or scanned MMU table **
;** **
;** © 1999-2000 THOR Software, Thomas Richter **
;*************************************************************************
; 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.
