Installation
¯¯¯¯¯¯¯¯¯¯¯¯
Make sure you have AHI installed properly before proceeding.
Copy paula.audio from this archive`s DEVS/AHI/ directory to
"DEVS:AHI/" to replace the existing file.
You may need a reboot.
If you should insist on using 14 Bit AHI on 68000/68010, please
copy paula.audio.000 to devs:AHI/paula.audio instead of the
default 68020 binary.
The 14 Bit Calibration utility can be copied anywhere. It does
not require a special installation procedure. Please follow the
guidelines given when starting the program. The updated utility
can perform stereo calibration, which is enabled as of the 4.33
release of this AHI driver. Some presets for typical OCS Paula
(8364R7) and ECS Paula (8364R7PD,8364R7PL) chips can be selected
by the menu strip as respective starting points, if desired.
