Cleanup IDE and PPIDE drivers

- The use of hardware reset has been improved such that it is generally only used at initial boot up. - Minor improvements to CF card detection and initialization. - Implement a simple wait mechanism to accommodate the startup time of the RC2014 SD Pico module. - Front panel I/O port for SC series of systems has been moved to 0x00 which is consistent with all other systems and avoids some I/O conflicts.
Fix IDE Detection on Spinning Disks

Wayne Warthen	9f71fe05aa	Cleanup IDE and PPIDE drivers - The use of hardware reset has been improved such that it is generally only used at initial boot up. - Minor improvements to CF card detection and initialization. - Implement a simple wait mechanism to accommodate the startup time of the RC2014 SD Pico module. - Front panel I/O port for SC series of systems has been moved to 0x00 which is consistent with all other systems and avoids some I/O conflicts.	2023-04-30 12:03:16 -07:00
Wayne Warthen	ad3c533145	Fix IDE Detection on Spinning Disks Prior improvement to IDE device detection broke detection of spinning hard disks. IDE registers cannot be used prior to device init completion (spin up). Not a problem for CF, but special steps required to ensure devices are fully initialized before register testing.	2023-04-23 18:47:43 -07:00
Wayne Warthen	e43a939f54	Improve IDE Device Detection Per issue #343, some systems could initially detect a non-existent IDE device which would cause a long time-out. This should resolve the issue.	2023-04-21 17:08:18 -07:00
Wayne Warthen	e5b7409f44	Support Per-floppy Device Drive Types - Floppy devices are now configured per-device so that each floppy drive can be different (e.g., first floppy is 3.5" and second floppy is 5.25"). - Removed need to use termination signal on floppy sector I/O. Addresses issue #318	2023-04-20 16:24:14 -07:00
