DOS XL - Patch

Patch

Version 2.30P was a newer version to 2.30 to fix two problems.

  • In previous versions of DOS XL, if you initialized a disk from the menu, the disk would not boot unless the file MENU.COM was on the disk. To alleviate this problem, type Q to quit the menu. Then type INIT or INITDBL from the command processor. Note: everything on the menu can be done manually from the command processor.
  • If you have a multidrive system and you initialized a disk in a drive other than one, when booted, the disk will always come up with the number of the drive on which it was initialized. To prevent this problem, use D1: as the destination drive.

The patch for DOS XL 2.30 to make it a 2.30P:

10 XIO 36,#1,0,0,"D:DOS.SYS" : REM unprotect file 20 OPEN #1,12,0,"D:DOS.SYS" 30 READ CNT:IF CNT=0 THEN GOTO 300 40 READ START 50 FOR ADDR=START TO START+CNT-1 60 READ BYTE:POKE ADDR, BYTE 70 NEXT ADDR 80 GOTO 30 200 DATA 3,5481,32,1,21 210 DATA 27,5377,141,217,22,169,16 220 DATA 141,23,22,,169,23,141,24,22 230 DATA 169,49,141,30,22,169,64,133 240 DATA 12, 169,21,133,13,96 250 DATA 0 300 CLOSE #1 310 END

Famous quotes containing the word patch:

    I sing a hero’s head, large eye
    And bearded bronze, but not a man,

    Although I patch him as I can
    And reach through him almost to man.
    Wallace Stevens (1879–1955)

    Whatever patch of limb
    he gazes on
    with unblinking eyes,
    I cover up
    but I want him to see it all anyway.
    Hla Stavhana (c. 50 A.D.)

    Imperious Caesar, dead and turned to clay,
    Might stop a hole to keep the wind away.
    O that that earth which kept the world in awe
    Should patch a wall t’expel the winter’s flaw!
    William Shakespeare (1564–1616)
