Short: IPatch 3.3 - Interrupt Speedup Patch Author: *Art Uploader: Jess Sosnoski (jlsosn planetx bloomu edu) Type: util/boot Architecture: m68k-amigaos ===================================== IPatch - Interrupt patch 3.3 (C) 1993 Arthur Hagen FreeWare - *ArtWare ===================================== [ This advertising space is for sale] ===================================== Yet another useless ArtWare-utility. This one works only for kickstart 37.175, and will replace some of the default system interrupt servers (which are about the most heavily used code on the Amiga) with more optimised code doing excactly the same. Some system speed increase when multitasking should be the result - even more if you have available 32-bits ram. Note - the speed increase will not be appearent or very low in speed-test-programs, as these usually disables interrupts when testing the system perform- ance. IPatch should be totally transparent to the system, and should not cause any other software to malfunction. No warrants given, though - some badly written software may set the interrupt vectors in a non- system-friendly way, and could cause problems. IPatch WILL score "Enforcer-hits" and show altered vectors in virus- test programs, but this is due to how IPatch does its job by patching vectors. To use IPatch, run it from CLI, or put it in your S:Startup-Sequence or S:User-Startup. If you experience problems (gurus) with IPatch, try SoftIPatch instead - this is a somewhat "kinder" version that doesn't bang the hardware vectors at all. But it is a weeny bit slower. New in version 3.3 compared to 3.0: Now there is a "HardIPatch" that should work with 3.0+ machines too. Some routines speeded up. New in version 3.0 compared to 2.9: Optimised even further. Non-68010-equipped machines should benefit most from the new code. Two more interrupts patched. New in version 2.9 compared to 2.8: A few cycles shaved off. New in version 2.8 compared to 2.5: Hardware interrupts somewhat faster. Should work on 68000 machines, and also with the KS in RAM. Thanks to Colin Plumb for an informative bug report. Some bugfixes - don't remember what I did... This program is FreeWare. And since you don't pay anything for it, don't expect me to feel guilty if this program by accident causes your machine to show pictures of your mother-in-law, or starts calling every friendly nuclear launch silo with fake orders... If you REALLY like this program, you can send me a pack of tobacco, some beer, or your sister as payment. (If sisters are scarce, any female relative between [legal age - fill in] and 40 will do.)
