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.
IMM Driver has rational timeouts now. It also lights the MG014 LED during activity.
The PPA skeleton just attempts to determine if the PPA interface is present. It does not attempt any I/O.
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
- Updates DEVICE call for all CIO devices to return unit mode and I/O base address
- Improved experimental XModem (XMX.COM) that uses direct hardware I/O for UART and USB-FIFO devices
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.
