This is a fixed version of the
RAMBOOT3 file that's distributed
with the official release archive of
MYDOS v4.50. The program initializes
the RAMDISK, copies DUP.SYS and
MEM.SAV to it, then finishes by
copying any files it finds in a
subdirectory named RAMDISK.
Due to a transcription error in the
source code, the copy routines work
much slower than they should. If
you've been using this program and
have been wondering why it takes so
long, then try this one. Rename
RMBOOT3A.AUT to AUTORUN.SYS (or
whatever you need for a Bootfile
name.)
Following is the section of code
from the original RAMBOOT3.M65 that
has been changed:
3540 ;COPY DUP.SYS FROM D1: TO D8:
3550 ;
3560 COPIES LDX #$30
3570 LDA #12
3580 STA ICMD,X
3590 JSR CIOV
3600 JSR CLOSIT
3610 SEC
3620 LDA MEMTOP
3630 SBC #BSS&255
3640 STA BUFLEN
3650 LDA MEMTOP+1
3660 SBC #BSS/256
3661 ;bug fix!
3662 ;following was STA BUFLEN
3670 STA BUFLEN+1
Hope you find this useful.
