- This diskette contains two files:
-
- DOSPATCH.COM -- patches IO.SYS
- DOSPATCH.DOC -- this file
-
- The DOSPATCH.COM file patches the retail MS-DOS 3.2 file IO.SYS. This
- patch corrects problems encountered when running FORMAT, DISKCOPY,
- DISKCOMP, and XCOPY when using an IBM BIOS dated after April 1986 or
- a Phoenix Technologies Ltd. BIOS version 3.00 or greater.
-
- This patch is applicable only to the retail version of MS-DOS 3.2 from
- Microsoft and NOT to PC-DOS 3.2 or the Phoenix Technologies Ltd
- implementation of MS-DOS 3.2.
-
- To install the patch first make a copy of your original MS-DOS program
- diskette (disk 1 or 2) using the DISKCOPY command. INSTALL THE PATCH
- ON THIS BACKUP DISKETTE. The patch will only work if the hidden file
- IO.SYS is in the correct place on the diskette.
-
- Enter the command DOSPATCH <drive letter>: to patch IO.SYS. For instance:
-
- DOSPATCH A:
-
- This command would cause the IO.SYS file on the diskette in drive A to be
- patched.
-
- After the patch is done you may install or reinstall DOS onto your hard
- disk using the SYS command or the FORMAT command (if the hard disk has
- not been formatted.)
