Thanks for this nice program ! I have slightly modified it, see attached files: 1) Modified for gas syntax 2) Added the following thing to avoid the crash. sub.l #64,d0 | stack adjustment for buggy OS I think the MiNTLib should be fixed like that. 3) Additional stuff displayed. Here is the output on my problematic system: Basepage = $0272C000 Initial SP = $02B2DFD8 High TPA = $02B2E000 I use aranym-mmu.exe 0.9.8 beta on Windows. See the attached config. There is the following line : FastRAM = 32 My kernel is FreeMiNT v1.16.3-ALPHA compiled May 1 2005 I don't know if it is an official version or not. My MINT.CNF is attched. The following lines are interesting : KERN_MEM_PROT=YES KERN_SECURITY_LEVEL=2 KERN_MPFLAGS=1 TPA_INITIALMEM=4096 I have set_mmu.prg in the AUTO folder, too. The attached file MMUSETUP.CNF is in my C:\I didn't manage to reproduce the problem on another ARAnyM setup, however I didn't try a lot.
I hope this information will be useful for memory protection gurus. -- Vincent Rivière

The logical and physical # addresses are set equal in most cases. The CPU always uses logical # addresses to access memory, and then uses to tranlation tree to # obtain the actual physical address of that memory. # size - The size of the block. # pd_flags - This is used to set initial flags in the page descriptors, as the # tree is built.

Old keywords are still supported, however, you # cannot use this configuration file for older versions # of MiNT! # The term `sysdir' we use here is short for `system directory' and # means the directory, where you keep your mint.cnf file, your # modules (XFS and XDD files) and other such system binaries. The # sysdir value is usually u:/c/mint. # # For clarity, it is assumed all over this example file, that your # boot drive is C:, and, if you have installed SpareMiNT distribution, # that your SpareMiNT drive is E:.

Very fast # machines however, may benefit from setting 1 here. #KERN_SLICES=2 # KERN_DEBUG_LEVEL controls output of global debugging information. # The higher the level, the more stuff MiNT will spew about about # what it's doing. # # The average user doesn't want to hear about this stuff, so the # default is 1, i.e. display ALERT messages only. Note that you need # a debug kernel to get more: normal kernels do not contain so much # debug information. # # KERN_DEBUG_DEVNO is the BIOS device number to which the info # should be sent. # # Devno can be: 0=printer, 1=aux/modem, 2=screen (console), 3=midi, # 4=keybrd, 5=raw. # # The default is the console. #KERN_DEBUG_LEVEL=1 #KERN_DEBUG_DEVNO=2 # KERN_BIOSBUF controls how BIOS I/O is performed. Normally, MiNT # tries to buffer this to provide a (considerable) improvement in # speed. However, some applications may get upset by this. # # KERN_BIOSBUF=NO turns off all buffering for maximum compatibility. # The default is YES. KERN_BIOSBUF=YES # KERN_SECURITY_LEVEL= enables the appropriate security level: # # 0 - recommended for single user setups, like MultiTOS (default). # 1 - recommended for multiuser setups, like KGMD. # 2 - full protection, unsupported by software, thus discouraged. KERN_SECURITY_LEVEL=2 # KERN_MPFLAGS controls the memory protection behaviour. Its argument # is a bitfield. Only the bit 0 is defined: 1 means, that more strict # model of the protection should be enabled. Some programs may # refuse to run, so the default is 0. KERN_MPFLAGS=1 # TPA_FASTLOAD=YES forces fast loading (without zeroing all the # memory) for all programs. This defines a default state, that can be # modified later via appropriate kernel calls (use MiNT Setter # utility to toggle it later when neessary, without reboots). # # TPA_FASTLOAD=NO (default) means that the information from the # program header will be used to decide (this is like TOS does). TPA_FASTLOAD=NO # Set maximum additional TPA size for new processes # (in kilobytes). The default is 1024. Better keep it low (1024 is # what we call low) if your machine has 4 MB RAM or less. TPA_INITIALMEM=4096 # FS_NEWFATFS= enables the new FAT filesystem driver for selected FAT # filesystems. The old TOS FS will be used otherwise. # # The default depends on whether the TOSFS driver is compiled into the # kernel or not. If it is, all drives are TOSFS by default.
