From User Updates - June 1983 - IBM Personal Computers "Future User Updates will be available at your Authorized IBM Personal Computer Dealer." Software Tips: "Correcting erroneously reported read/write errors resulting from DISKCOMP and DISKCOPY commands in DOS 1.1 and DOS 2.0 In DOS 1.1 and 2.0, the DISKCOMP and DISKCOPY commands may erroneously report diskette read and/or write errors on tracks 40 and over. This may occur on memory systems that are large enough to store the entire contents of a double-sided diskette. To correct this, use the following DEBUG patches: For DISKCOPY, type: A>DEBUG DISKCOPY.COM -E861 E8 74 00 -E8D8 3D 51 00 72 02 B0 50 A2 36 05 C3 -RCX When the DEBUG utility displays: CX 07D8 type: :7E3 -W -Q For DISKCOMP, type: A>DEBUG DISKCOMP.COM -E6EC E8 79 00 -E768 3D 51 00 72 02 B0 50 A2 95 04 C3 -RCX When the DEBUG utility displays: CX 0668 type: :673 -W -Q" [ Of course never do this to your original copy of DISKCOPY and DISKCOMP, ed. ] This particular issue of User Updates also included fixes for Multiplan (how to install Multiplan with DOS 2.0) and PASCAL (to fix a bug that caused false "out of memory" errors on IBM PCs with large memory).
