      From: abuse@telia.com              > 1. I'm concerned after reading some of the articles and posts about the       > RT200 bug that once processors get fast enough we will run into it (or       > similar) again               For that to happen, the processors must get 65,000 times faster than       the old 200MHz processors. I'd say that'll hardly happen in our       lifetime. 8-)              > if we didn't apply the right patch, and I want to be able       > to determine what patch was applied.               As many already have pointed out, the patch is done to CRT.ASM, that       you should have in the \RTL\CRT\ subdirectory, if you have a properly       installed BP7. The patch is very simple, it's just a few changes in the       One-time Initialization routine in the beginning of the file. See below       (the original code is in capital letters, my changes in small):                            @@2: CMP BL,ES:[DI]        JE @@2        MOV BL,ES:[DI]        MOV AX,-28        CWD        CALL DelayLoop        NOT AX        NOT DX        MOV CX,55        mov si, ax        mov ax, dx        xor dx, dx        div cx        mov DelayCntHi, ax        mov ax, si        DIV CX        MOV DelayCnt,AX                                   --        FidoNet in your news reader: news://felten.yi.org        For full access, register at: http://felten.yi.org/join.html              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
