This is necessary -because at cold start, the CPU is executing code in lower -memory which is the same area that is bank switched. - -Phase 1 of booting copies phase 2 code to upper memory -and jumps to it to continue the boot process. - -Phase 2 of booting manages the setup of the RAM page -banks as needed. In the case of a hardware startup, -phase 2 just copies the code from ROM page 1 into RAM -page 1 and executes the loader. In the case of an -application startup (.com file used to load a new -copy of the system), phase 2 copies the first 32KB -of the application memory space into RAM page 1 -and executes the loader. - -See 'bootrom.asm' for the implementation of the ROM -(hardware) startup. See 'bootapp' for the implementation -of the application based startup. - -General Design Strategy ------------------------ - -The design goal is to locate as much of the hardware -dependent code as possible out of normal 64KB CP/M -address space and into a bank switched area of memory. -As calls are made to HBIOS, the lower 32KB of memory -is switched to 'bank 1' which contains all of the -driver code. The operating system is unaware this -has occurred. As control is returned to the Operating -System, the lower 32KB of memory is switched back to -normal 'bank 0'. - -HBIOS implements a small 'shim' (proxy) that lives in the -upper page (256 bytes) of RAM. This shim is responsible -for handling the HBIOS call invocations. It is the -target of 'RST 08' and will simply switch in RAM -bank 1 into lower RAM forward the call to the lower -memory, then switch lower memory back to RAM bank 0 -on return. - -In the case of CP/M and ZSDOS, CBIOS is built to -utilize HBIOS for most of the work. CBIOS contains -the required CP/M data structures such as DPH and DPB -and is responsible for translating and forwarding work -to HBIOS as needed. - -Notes ------ - -1. Size of ROM disk and RAM disk will necessarily be -decreased by 32KB each. User will need to make sure -that RAM disk is reformatted (CLRDIR). \ No newline at end of file diff --git a/branches/dwg/Doc/ChangeLog.txt b/branches/dwg/Doc/ChangeLog.txt index bc38f0d1..09b3c8bc 100644 --- a/branches/dwg/Doc/ChangeLog.txt +++ b/branches/dwg/Doc/ChangeLog.txt @@ -1,3 +1,16 @@ +Version 2.5 +----------- +- WBW: Implemented CRT driver model (video and keyboard) +- WBW: Implemented ANSI terminal emulation +- WBW: Updated build process to remove CPU specification +- WBW: Refactored VDU and Color VDU drivers for new cRT driver model +- WBW: Refactored keyboard drivers for new CRT driver model +- WBW: Refactored PPIDE driver to improve performance +- WBW: Implemented "boot" messaging +- WBW: Fixed debug monitor (I, O, and H commands corrected) +- WBW: Added support for SCSI2IDE (SD Card driver primarily) +- WBW: Revised System Architecture document + Version 2.1.1 ------------- - WBW: Corrected setup of Z180 wait states @@ -14,7 +27,7 @@ Version 2.1 Version 2.0 ----------- - WBW: Implemented Banked BIOS (drivers in separate bank) -- DGG: Updated in-site flash utility for greater chip compatibility +- DGG: Updated in-situ flash utility for greater chip compatibility - WBW: Updated FDTST to latest version (improved support for 5.25" and 8" media) - WBW: Added ParPortProp driver - DWG: Entire new suite of Apps written in Aztec C diff --git a/branches/dwg/Doc/Ecma-035.pdf b/branches/dwg/Doc/Ecma-035.pdf deleted file mode 100644 index b7913cf5..00000000 Binary files a/branches/dwg/Doc/Ecma-035.pdf and /dev/null differ diff --git a/branches/dwg/Doc/Ecma-048.pdf b/branches/dwg/Doc/Ecma-048.pdf deleted file mode 100644 index e1441c5e..00000000 Binary files a/branches/dwg/Doc/Ecma-048.pdf and /dev/null differ diff --git a/branches/dwg/Doc/HBIOS Functions.txt b/branches/dwg/Doc/HBIOS Functions.txt deleted file mode 100644 index 7ae032c9..00000000 --- a/branches/dwg/Doc/HBIOS Functions.txt +++ /dev/null @@ -1,4 +0,0 @@ -HBIOS FUNCTION CALLS -==================== - -HBIOS function calls are now documented in "RomWBW Architecture.pdf".
