Wayne Warthen	457aa44832	SD Card Compatibility Improvement - Modified SD driver to keep SD card clock consistently fast after card init. This only seemed to effect a Lexar 32GB uSD Card on CSIO interface. Thanks and credit to Richard Deane for reporting this. - Improved hard disk layout documentation.	1 year ago
Wayne Warthen	7e2b2b8f40	Implement SIOINTS Setting in SIO Driver - SIOINTS allows disabling use of interrupts in the SIO driver when interrupts are enabled globally. It will not allow you to enable SIO interrupts if interrupts are globally disabled (INTMODE 0).	2 years ago
Wayne Warthen	e68cbded97	SD Card Speed Improvement for FZ80 - Removed wait routines for FZ80 in SD driver. Latest FPGA code does not require them. - Minor improvements to disk layout documentation.	2 years ago
Wayne Warthen	91debe53c4	Improve Startup Commands Documentation	2 years ago
Wayne Warthen	8e0af1720a	Application Boot Tweaks - Reduces failure scenarios with application boot - Catches and diagnoses common bank mismatch which application boot cannot handle	2 years ago
Wayne Warthen	83d26a4faf	- Improve PPIDE Device Detection - Some PPI chips were falsely detecting the presence of an IDE device. Added code to preset PPI register with a value that avoids false positives.	2 years ago
Wayne Warthen	888706149d	Improve Application Start Mode - If the new AUX bank happens to be the same as the old HBIOS bank, an application start would fail. Relocated the copy to avoid this.	2 years ago

Wayne Warthen	cdc2b3964d	Remove Short IDE/PPIDE Timeout, Issue #397 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.	2 years ago
Wayne Warthen	21b2eee7ab	Add Beep Function to Sound Driver Interface, Issue #402	2 years ago
Wayne Warthen	b80d395266	Update for Les Bird's Graphics/Sound/Joystick Module - Unique I/O configuration for Les Bird's Graphics/Sound/Joystick Module has been removed because the module now conforms to generic MSX port conventions.	2 years ago

Wayne Warthen	8c4a3d2b3d	Final Video Hardware Reset Changes - Modified TMS driver to always imbed an uncompressed font. This is because I have found no reasonable way to decompress a font while an OS is still active without mangling some of the OSes RAM.	2 years ago
Wayne Warthen	585c892a54	Add Genesis Platform ID (STDZ180)	2 years ago
Wayne Warthen	49025dca44	Cleanup - Documentation update - Fixed minor screen anomaly related to new video reset handling	2 years ago
Wayne Warthen	2d8c37307d	Improve Video Hardware Reset - This change avoids clearing the screen every time an OS reset occurs. A non-destructive VDC reset is now performed that leaves the screen contents and cursor position unchanged. - If an application overwrites the video RAM, then the screen may contain garbage upon return to OS. However, the console will still be functional and the user can just press enter a few times to clear the screen.	2 years ago
