Use a global flag to indicate if interrupts have been enabled during the boot process. Drivers that operate in the pre-interrupt phase can use this to manage interrupt disable bracketing.
This allows restoring the location of interrupt enable in the boot process to it's proper location.
- 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.
-
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.
- Renamed Centronics driver from "CEN" to "LPT" based on input that LPT is the more recognized name for IBM compatible Centronics interfaces.
- Modified LPT hardware detection to be more generic (no longer depends on MBC-specific hardware implementation).
- Fix to CPU speed display for SBC v2 (004 and above) speed selection mechanism.
