- 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.
-
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.
- Added WDATE command courtesy Kevin Boone. See https://github.com/kevinboone/wdate-cpm for more information.
- Final cleanup of PPA/IMM/SYQ drivers including CPU speed compensated timeouts.
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.
