Based on input from Martin R, the console takeover mechanism has been modified to require that the space bar be pressed twice in a row on the character unit desiring to be the console. This reduces the chance of a spurious console takeover due to garbage input on serial ports.
- If enabled by AUTOCON config setting, you can press <space> at any character device to take over the console at the boot loader prompt.
- Correction to SIOSEEK documentation in System Guide. Thanks and credit to Martin R.
- 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.
Driver Device Type ID's have been stored in the upper nibble. However, running out of ID's, I have changed them to occupy the entire byte.
This is a breaking change, so I have updated the minor version number to maintain integrity between components. So, v3.3 will never become a stable release and I am moving directly to v3.4.
- The build process was enhanced by Dean Jenkins to support the Raspberry Pi. Note that the Propeller firmware will not be generated by a RPi build. See Issue #358.
- Initial support for USB storage via CH375/6.
The QPM portion of the build has been updated to dynamically combine the current CBIOS with the static QPM CCP and BDOS binaries. This will keep the QPM system image up to date and avoid HBIOS version mismatch warnings.
- Support is limited to 512 byte sectors. So, devices such as ATAPI Zip Drives will work. CD-ROM devices will not because they use a larger sector size.
- Floppy devices are now configured per-device so that each floppy drive can be different (e.g., first floppy is 3.5" and second floppy is 5.25").
- Removed need to use termination signal on floppy sector I/O.
Addresses issue #318
A full implementation of UCSD p-System IV.0 for RomWBW. Derived from the official Z80 Adaptable p-System.
My first real programming was on this system. So many memories...
- Fixes to ZPMLDR to make it functional with RomWBW.
- Incorporate fixes from the Jon Saxton disassembly in ZPM3 itself.
- Credit to Lars Nelson for finding the ZPM3 source (disassembly).
- The UART driver has been enhanced to allow use of interrupt driven receive buffer and RTS flow control. It will only be used if enabled and the chip detected has no auto-flow control capability.
- Reorganized most of the "common" files into special directories.
- Fixed bug affecting application boot related to ROM checksum test.
- Added support for LiNC sound card at default port address.
