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. >>don lebow 10/92
