The Microdrives behave slightly differently than either normal spinning drives or CF Cards. This update removes the "short" timeout that is used in the IDE/PPIDE drivers which caused timeout issues for the Microdrives.
The short timeout was originally used to workaround excessive wait/stall during boot of some media. I don't think it is necessary any more because of additional intelligence in the initialization routines.
- Rearranged HBIOS code to improve colocation of related code.
- Implemented macros to improve control over assembly diagnostic output.
- Improved handling of diagnostic LEDs.
- Improved application boot bank management.
- Implemented application boot for Z280 systems.
- Moved Z280_BNKSEL into proxy.
-
- The post-reset delay of both the IDE and PPIDE drivers has been extended. The SD-IDE adapters need more time to initialize before being ready to behave as proper IDE devices.
- Added support for the FDC section of the Duodyne Disk-IO board.
Added a new driver category for DSKY (Display/Keypad) devices. Existing DSKY devices were converted into drivers ICM and PKD. These devices were previously DSKY and DSKYNG.
This removes substantial code duplication and recovers significant space in romldr and dbgmon.
- Modified the Disk Device function call (DIODEVICE) to provide new attributes related to disk size and removability.
- Leveraged API change to allow handling drive assignment differently depending on ATAPI vs. ATA interface.
- Support is limited to 512 byte sectors. So, devices such as ATAPI Zip Drives will work. CD-ROM devices will not because they use a larger sector size.
- 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.
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.
In the IDE and PPIDE drivers, a CF Card is differentiated from a Hard Disk using the first word of the result of the IDENTIFY DEVICE command. The value 0x045A was recently added because it was seen from a CF<->SD Card adapter. However, the value has now been seen from a spinning hard disk. Since the value is ambiguous and not defined in the CF Card specs, I am removing it from the list of CF Card signatures.
Credit to Mark Elkin for identifying this and helping me track it down.
As suggested by Laszlo Szolnoki, I have added an additional CF Card signature to the IDE and PPIDE drivers. He also pointed out a deficiency in the disk size printing which has been addressed.
- The DSKY(ng) can display disk I/O activity as the system runs. This capability was implemented very erratically. This update overhauls the mechanism, makes it consistent, and implements it across all disk drivers.
- DSKYng now has same features as original DSKY including debug monitor
- Added support for MBS LEDs
- Elevated MBS to a platform instead of just a sub-config of SBC

* HBIOS Makefile - use env vars for target
Allow build ROM targets to be restricted to just one platform thru use of ENV vars:
ROM_PLATFORM - if defined to a known platform, only this platform is build - defaults to std config
ROM_CONFIG - sets the desired platform config - defaults to std
if the above ENVs are not defined, builds all ROMs
* Added some more gitignores

* makefile: updated some make scripts to use when calling subdir makefiles
* linux build: update to Build.sh fix for some platforms
The initialization of the Rom dat file used the pipe (|) operator to build an initial empty file.
But the pipe operator | may sometimes return a non-zero exit code for some linux platforms, if the
the streams are closed before dd has fully processed the stream.
This issue occured on a travis linux ubuntu image.
Solution was to change to redirection.
* Bump version
* Enhance CTC periodic timer
Add ability to use TIMER mode in CTC driver to generate priodic interrupts.
* HBIOS: Added support for sound drivers
New sound driver support with initial support for the SN76489 chip

* SN76489_PORT_RIGHT .EQU $F8 ; PORTS FOR ACCESSING THE SN76489 CHIP (LEFT)
* Miscellaneous Cleanup
No functional changes.

Drive letters are now only pre-assigned to hard disk type devices that have media inserted. Media can still be inserted on-the-fly and drive letters assigned using ASSIGN.
Supports double-buffered disk i/o to read/write to/from any memory bank specified.
NOTE: Disk I/O will be temporarily slower than normal because all I/O is being forced thru double-buffering for testing.
