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.
- Additional HBIOS reorganization - no functional changes (in theory)
- Upgrade to v1.3.8 of FLASH4 from Will Sowerbutts
- Upgrade to FAT v1.1 based on input from Peter (@z80micro-mc)

- 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.
-
- PS2INFO now provides a small startup menu to select either MBC or RHYOPHYRE (needs to be expanded to other platforms).
- Battery condition testing enabled by default in RHYOPHYRE.
- Z180 system timer enabled by default in RHYOPHYRE.
- Default ACR in RHYOPHYRE now turns on the status LED to indicate hardware is alive early in boot process.
Allow specifying a character code which, upon receipt, will reboot system. Only useful/implemented for interrupt driven serial drivers. Currently only implemented for ASCI and SIO. Do *not* use this unless you fully understand the ramifications!!!
- New Z280 bank selection routine that does not require gigantic table and is about as fast.
- Bump Z280 UART driver to 128 byte buffer.
- Truncate unused portion of Z280 IVT at end.
- Complete initial support for Karl's Z280 module w/ 512K RAM/ROM module
- Allow swapping Z180 serial ports via ASCISWAP config variable
- Fix Z180 include file per Issue #141 from J.B. Lang
- Updates DEVICE call for all CIO devices to return unit mode and I/O base address
- Improved experimental XModem (XMX.COM) that uses direct hardware I/O for UART and USB-FIFO devices
