- 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.
- Credit and thanks to Martin R for providing a substantial list of suggested fixes and improvements to the User Guide. I have done my best to address them -- others will require more time and will hopefully be addressed in the future.
- The 40 column mode of the TMS driver now conforms to the memory map from the TMS9918 documentation and is also now consistent with the existing TMS9918 video programs from the RC2014 forum.
Experimental command line script (Windows only) to add a ROM image to user area 0 of hd1k_combo.img. Intended to make it easier to get a ROM image to a system for subsequent FLASHing.
When using the Z2 memory manager, if the HBIOS exceeds 16K, RTCDEFVAL will not be accessible prior to programming the Z2 memory bank registers. In this corner case the RTC latch could be mis-programmed. This commit introduces a workaround.
- ACIA driver was not properly returning ZF to indicate if it handled an interrupt.
- APPBOOT was failing on ROMless systems because it was copying the HBIOS code overtop of itself.
Based on input from Issue #364, I have attempted to clarify a few areas on the User Guide:
- Recommendation to only use ROM OSes only for limited purposes
- Added a more detailed description of the automatic drive assignment algorithm
- Added more detail on batch file auto-submission
- Fix ensures that the speaker control bit is set the same as it was initially after playing a tone.
- Reserve 2 bytes in the proxy for a platform dependent tick counter value. Currently for HEATH platform.
- Added support for Duodyne to PS2INFO application.
- Switched all build paths to consistently use OpenSpin since it appears to be compatible with all build environments supported by RomWBW.
- Added support for Duodyne Multi-IO board
- Added support for Duodyne Zilog-IO board
- Added SUPCTS equate in hbios.asm to allow selectively adding code to suppress use of CTS during HBIOS boot
- Added reference in User Guide to Bruce Hall's Assembly Language Programming document
- CP/M 3 ldrbios had not been properly updated for device type id change.
- ASSIGN command was not handling DPB's correctly due to device type id change.
