b1ackmai1er	e7ab778929	Slightly better handling of low HBIOS heap memory CBIOS reports *** HBIOS Heap Overflow, when the HBIOS is big (i.e. lots of included drivers) Trigger build failure when CCP will not fit in heap. Slightly more informative CBIOS error message	3 years ago

Wayne Warthen	816234f0fa	More Cleanup	3 years ago
Wayne Warthen	2f3fb51884	More Cleanup - Tweaks to SURVEY and PORTSWP to improve port detection accuracy and handle Z280 better - Recover a lot of wasted space in dbgmon using a few built-in utility routines instead of entire util.asm - Improve the (D)evice command in romldr to use the HBIOS routine which is much more complete and saves space	3 years ago

Wayne Warthen	2271c086b5	Minor IDE/CF/SD Disk Handling Updates As suggested by Laszlo Szolnoki, I have added an additional CF Card signature to the IDE and PPIDE drivers. He also pointed out a deficiency in the disk size printing which has been addressed.	3 years ago
Wayne Warthen	2b4631195a	Misc Updates Based on Input from Eluan Miranda I got a very nice email from Eluan Miranda. He pointed out a few inconsistencies in the video and audio driver configurations. I made a few adjustments to clean things up.	3 years ago

Wayne Warthen	aceef15481	Support DS1501 RTC jpelletier provided a DS1501 RTC driver. This commit integrates the driver into HBIOS.	4 years ago
Wayne Warthen	94c32c9fd0	Mostly Build Improvements - ROMSIZE is now a configuration variable instead of a command line parameter. - Added CP/M license information based on new email from Bryan Sparks.	4 years ago
Wayne Warthen	11ea0c8c27	Add Speaker Beep Added a generic routine in HBIOS to play a beep sound on the first available sound device. Implemented the beep in the ANSI and TTY terminal emulators.	4 years ago
Wayne Warthen	44b17ccc3a	Improve Centronics Compatibility - Renamed Centronics driver from "CEN" to "LPT" based on input that LPT is the more recognized name for IBM compatible Centronics interfaces. - Modified LPT hardware detection to be more generic (no longer depends on MBC-specific hardware implementation). - Fix to CPU speed display for SBC v2 (004 and above) speed selection mechanism.	4 years ago
Wayne Warthen	b2e1294452	Correct AY38910 Off By 1 Octave Issue I think this update corrects a long-standing issue in which the AY38910 driver played notes off by one octave.	4 years ago
Wayne Warthen	a62f5805ca	Add BOOT_DELAY Configuration Variable Some systems use terminal devices (Raspberry Pi, etc.) that take a few seconds to be ready to display console text. The BOOT_DELAY setting can be used to introduce an arbitrary delay (in seconds) in the boot process just prior to text output. This can be used to avoid missing some of the boot messages.	4 years ago
Wayne Warthen	982906757e	Support QP/M TIMDAT Routine QP/M is a CP/M 2.2 replacement for BDOS/CCP. However, it adds it's own concept of date/time stamping. Support for the QP/M date/time routine has been added. You can configure QP/M to find the vector at address 0x0010. A sidenote on QP/M. By default, it uses 2 bytes at address 0x0008 to store the current drive/user. This will conflict with RomWBW's use of RST 08 for API function calls. I recommend using address 0x000E when configuring QP/M for the location of the current drive/user.	4 years ago

Wayne Warthen	b98ee17e14	Plumbing for uPD7220 GDC Driver	4 years ago
Wayne Warthen	4a88e0bcae	Improve Z180 Variant Handling - There were several places that RomWBW was making incorrect assumptions about what the older Z180 CPUs could do. These have been corrected.	4 years ago

Wayne Warthen	5d81574226	Preliminary Support for ROMless Booting	4 years ago
Wayne Warthen	9f3c9e180d	Add PIO Driver - Just a stub that detects and initializes the hardware.	4 years ago
Wayne Warthen	51d9bdb655	Minor ASSIGN Fixes, Add 2PIOTST - Improved ASSIGN operation under CP/M 3 to better handle BIOS function invocations - Added 2PIOTST for testing the DUALPIO MBC board - Increased default RAM drive size for ZRC	4 years ago
Wayne Warthen	bf965c2604	Minor Z280 Fixes - Fixed the ROM VERIFY functionality on Z280. It was indicating errors incorrectly. - Revised the way that ZZRCC is built to remove a bunch of complexity that was causing issues. An implication of this is that ZZRCC now treats the data loaded from the CF Card as a ROM disk instead of a RAM disk. - Updated the assemblers to handle some more Z280 instructions used in HBIOS. - When building ZZRCC, checks have been added to ensure the ROM image is exactly 256K. The build defaults to 512K and that causes the ZZRCC disk image to be corrupted. This will stop the build if the user fails to specify a 256K ROM size.	4 years ago
Wayne Warthen	e6b9d2dcfd	Improve Z280 DMA Memory Copy The Z280 interbank memory copy uses DMA and did not properly handle scenarios where the source or destination memory range crossed over the banked/common memory boundary. It added a bunch of code, but it is fixed now. This seems to be required by CP/M 3.	4 years ago
Wayne Warthen	214ed54584	Miscellaneous - Fix build under Windows (credit to Dean Netherton for finding this). - Fix ReadMe.md file format to remove superfluous junk at top. - Improve RAM size detection (work in progress, not part of normal build).	4 years ago
Wayne Warthen	97aa0aae9f	Bug Fix Fixed a small issue in the boot management of the CPU speed for MBC and SBC platforms.	4 years ago
Wayne Warthen	92399fe537	More CPUSPD Tweaks I know I said I was done, but I found a few more things I decided to tweak. Functionality is unchanged.	4 years ago
