Short: switch DSack/BERR on A4000 Author: Holger.Hippenstiel@gmx.de (Holger Hippenstiel) Uploader: Holger Hippenstiel gmx de (Holger Hippenstiel) Type: dev/debug Version: 1.02 Replaces: dev/debug/BERM.lha Architecture: m68k-amigaos >= 2.0.4 Distribution: Aminet BERM V1.02 =========== This tool allows to switch to DSack/BERR (Bus-Error-mode) on a A4000. The default for 030 ist DSack, for 040/060 BERR. It's a kind of minimal "Enforcer", because the A4000-Hardware can regconize access to illegal memory. In DSack-Mode all illeal access are simply terminated, delaying for 170µs. In BERR-Mode an "Illegal Exception" will be called, if there is no Error-Handler your System will hang for ~1 second. Usage: BERM [o|c] ;default ist DSACK-Mode If option "o" is given BERR-Mode is selected If option "c" is ONLY Bus-Status will be printed. No changes are made. Example: 1> BERM c BERM: Bus TIMED OUT ! (DANGER) This means any programm wrote to a memory-location that does not exist. Update V1.02: Fixed a bug Jesper Matthiesen found, thanks.
