; 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! |
