DoubleSpace User Interface Text Not Visible on Plasma Display (98512)

WORKAROUND

You can work around this problem by using Debug to edit DBLSPACE.EXE and change the default colors.

NOTE: This procedure works for the DBLSPACE.EXE file provided with MS-DOS 6.0 (dated 3-10-93 with a size of 274484 bytes). It does not work with the DBLSPACE.EXE file provided on the Conversion Disk for Users of Stacker.

1. Make a backup copy of your DBLSPACE.EXE file. To do this, type the following at the MS-DOS command prompt and then press ENTER:

   copy c:\dos\dblspace.exe c:\dos\dblspexe.sav

2. Rename DBLSPACE.EXE before running Debug. To do this, type the following at the MS-DOS command prompt and then press ENTER:

   ren dblspace.exe dblspace.bw

3. Run Debug and edit the DBLSPACE.BW file. To do this, type the following at the MS-DOS command prompt and then press ENTER:

   debug dblspace.bw

4. Follow the steps shown in the table below. Press ENTER after each command shown in the "Command to ENTER:" column.
   
   NOTE: Debug displays a segment address in place of the "xxxx" shown below. For example, if the segment address is 2C0E, Debug displays the following after you enter the first edit command:

   2C0E:0BA4 74.

   In the commands where this segment address is represented with a "Yxxx", use a segment address that is calculated as follows:
   
   Add 3 to the left digit shown in the segment address (represented by "xxxx") that appears after you enter the first edit command. For example, if "xxxx" is equal to 2C0E, use 5C0E for the segment address in all commands that specify "Yxxx".
