Architecture: generic
Distribution: Aminet


This is a small fix for 'AMI_ATX.lha' (by Rafal 'MASTER' Siedlaczek). Rafal
has kindly given me source files and permission to modify and upload them.
This fix solves the problem of incompatibility with X-Copy and similar
programs: they would turn off the amiga, because AMI_ATX used a signal
driveselect for software shutdown.

The fix uses same signal, but requires a series of ones and zeros, to avoid
unwanted shutdown. I modified some timeouts, too. Now it waits 1sec instead of
2sec after poweroff button signal.

Archive also contains an external floppy drive pinout and related information.
Only the PIC_16F628 hex file is provided (no 16F84A as I couldn't test it).
The original archive (AMI_ATX.lha) is required as it contains schematics and
other info.

Because of its simplicity, this fix (and the original) should work on any
Amiga. I have tested it on A1200 with BPPC, and it works in both OS3.9 and
OS4.0. Still, I'm not sure if using driveselect this way is ok.  It might be a
good idea to remove diskettes from drives before using software shutdown.
