Improve OS Boot Drive Assignment

- Modified the Disk Device function call (DIODEVICE) to provide new attributes related to disk size and removability.
- Leveraged API change to allow handling drive assignment differently depending on ATAPI vs. ATA interface.

+Outside of the hardware platforms adapted to RomWBW, there are a variety

+a RomWBW-specific variation.
+
+## Z88DK
+
+Z88DK is a software powerful development kit for Z80 computers
+supporting both C and assembly language.  This kit now provides
+specific library support for RomWBW HBIOS.  The Z88DK project is
+hosted at <https://github.com/z88dk/z88dk>.

+## Paleo Editor
+
+Steve Garcia has created a Windows-hosted IDE that is tailored to
+development of RomWBW.  The project can be found at
+<https://github.com/alloidian/PaleoEditor>.
+
+## p-System Volume Management Script
+
+Andrew Davidson has created a Python script to automate the insertion
+and deletion of volumes within the p-System disk image.  These scripts
+are hosted at <https://github.com/robosnacks/psysimg>.

+## Z80 fig-FORTH
+
+Dimitri Theulings' implementation of fig-FORTH for the Z80 has a
+RomWBW-specific variant.  This fig-FORTH is built into the RomWBW
+ROM.  However, the project itself is hosted at
+<https://github.com/dimitrit/figforth>.

+## RomWBW Date/Time Utility
+
+Kevin Boone has created a generic application that will display or
+set the date/time of an RTC on RomWBW.  The application runs on all of
+the CP/M OS variants.  This tool (`WDATE`) is included on the RomWBW
