;*************************************************************************
;** 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 THOR Software, Thomas Richter **
;*************************************************************************
; the current version of the MMU library knows four 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.
;
; 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
; command 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 line 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
; A more complete setup can be computed by the "BuildMMUConfig.rexx" script
; in the "Install" drawer of the mmu.library distribution which will even
; consider P5 hardware and optimizations for graphics cards.
; that's all folks!
