IPatch - Interrupt patch 2.6
(C) 1993 Arthur Hagen
Released to the Public Domain
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 usu-
ally disables interrupts when testing the system performance.
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 2.6 compared to 2.5:
Should work on 68000 machines, and also with the KS in RAM.
Thanks to Colin Plumb for an informative bug report.
Enjoy,
*Art
