- @kiwisincebirth noticed some duplicative code in HBIOS related to warm starts. This has been refactored.
- A start mode code is now passed from HBIOS to RomLdr to indicate a warm or cold start. Device inventory now uses this code to display only on cold start.
- Add a signature to the start of the font map table to prevent accidentally applying/decompressing invalid font data.
- Improve Z280 font byte retrieval to properly restore the user mode bank.
Video soft font data was occupying a large amount of space in the HBIOS bank. This change moves the font data to a ROM bank by default.
Thanks and credit to @b1ackmai1er who provided much of the code that originated this change.

Jörg Linder has disassembled and thoroughly commented a great deal of the BPBIOS binaries. This was an incredible amount of work. I have added all of these to the RomWBW build scripts and will ultimately integrate them more completely.
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.
General cleanup and refactoring of the ROM bank layout mechanism in the build scripts. This will make it easier to add and adjust the components in the ROM banks.
This commit does not yet implement the pending bank layout changes. Those will be part of the next commit.
- Add a -DELAY switch to the TUNE command line to force the use of delay mode for note pacing. Issue #558 Credit to @robbbates for suggesting this.
- Add missing include file logic for DS1307, Issue #556. Credit to @tpycio.
- Miscellaneous documentation improvements per Peter Onion and Petr Antos.
- UNARC updated to UNARCU11 which fixes an edge case where the user number was being incorrectly changed. See #496. Thanks and credit to Lars Nelson for this.
The Monsputer was already omitted from the standard builds. It had almost no impact on the core code, so I have annotated some references to Monsputer as deprecated.
Resolved keyboard interrupt errors when a key is pressed during reboot. Turn off keyboard controller interrupt enable before cold boot process starts. I'm wondering if duodyne interrupt generator is immune to DI :)?
- I finally realized there was a much simpler way to setup the instance data pointer (IY) for the interrupt handler. This implements the change and reduces the complexity of the code.
