; |
|||
; THE COMPLETE SET OF DEFAULT CONFIGURATION SETTINGS FOR THIS PLATFORM ARE FOUND IN THE |
|||
; CFG_<PLT>.ASM INCLUDED FILE WHICH IS FOUND IN THE PARENT DIRECTORY. THIS FILE CONTAINS |
|||
; COMMON CONFIGURATION SETTINGS THAT OVERRIDE THE DEFAULTS. IT IS INTENDED THAT YOU MAKE |
|||
; YOUR CUSTOMIZATIONS IN THIS FILE AND JUST INHERIT ALL OTHER SETTINGS FROM THE DEFAULTS. |
|||
; EVEN BETTER, YOU CAN MAKE A COPY OF THIS FILE WITH A NAME LIKE <PLT>_XXX.ASM AND SPECIFY |
|||
; YOUR FILE IN THE BUILD PROCESS. |
|||
; |
|||
; THE SETTINGS BELOW ARE THE SETTINGS THAT ARE MOST COMMONLY MODIFIED FOR THIS PLATFORM. |
|||
; MANY OF THEM ARE EQUAL TO THE SETTINGS IN THE INCLUDED FILE, SO THEY DON'T REALLY DO |
|||
; ANYTHING AS IS. THEY ARE LISTED HERE TO MAKE IT EASY FOR YOU TO ADJUST THE MOST COMMON |
|||
; SETTINGS. |
|||
; |
|||
; N.B., SINCE THE SETTINGS BELOW ARE REDEFINING VALUES ALREADY SET IN THE INCLUDED FILE, |
|||
; TASM INSISTS THAT YOU USE THE .SET OPERATOR AND NOT THE .EQU OPERATOR BELOW. ATTEMPTING |
|||
; TO REDEFINE A VALUE WITH .EQU BELOW WILL CAUSE TASM ERRORS! |
|||

|||
; PLEASE REFER TO THE CUSTOM BUILD INSTRUCTIONS (README.TXT) IN THE SOURCE DIRECTORY (TWO |

Z1RCC has no real ROM. It has a single 512K RAM chip. The RomWBW |
|||
ROMless startup mode is used. |
|||
|
|||
The ROMless startup mode treats the entire 512KB as RAM. The entire |
|||
512KB of RAM (less the top 32KB) must be preloaded by the Z1RCC CF |
|||
Loader. There will be no ROM disk available under RomWBW. There will |
|||
be a RAM Disk and it's initial contents will be seeded by the image |
|||
loaded by the CF Loader. |

Notes |
|||
----- |
|||
|
|||
- At startup CPLD ROM is mapped to Z80 CPU address space 0x0000-0x003F, CPU begins execution at 0x0000 |
|||
- CPLD ROM (CF bootstrap mode) reads CF Boot Loader (512B) from start of CF (MBR) to 0xA000 and runs it |
|||
- CF Boot Loader reads Z1RCC Monitor (4KB) from sectors 0xF8-0xFF of CF to 0xB000 and runs from 0xB400 |
|||
- Z1RCC Monitor reads 480KB (RomWBW) from sectors 0x120-0x4DF of CF into 480KB of physical RAM |
