During Reconfiguration, Setup Won't Accept Correct Disk

• Microsoft Windows operating system versions 3.0, 3.0a, 3.1, 3.11

SYMPTOMS

When you run SETUP.EXE from Microsoft Windows to change the system configuration, the Setup program checks the hard drive for the necessary files. If the files are not already on the hard drive, SETUP.EXE refers to the SETUP.INF file for the locations of the files on the source disks and prompts you to insert the correct disk in drive A.

If you attempt to use 5.25-inch disks after originally installing from 3.5-inch disks or attempt to use 3.5-inch disks after originally installing from 5.25-inch disks, the Setup program may continue to prompt for the correct disk at some point during installation.

CAUSE

This problem occurs because the SETUP.INF files differ between the 3.5-inch and 5.25-inch versions.

WORKAROUND

If you no longer have the same size disks from which you originally installed, you can work around this problem by backing up the SETUP.INF file in the Windows SYSTEM subdirectory. Then replace it with the SETUP.INF file (which is not compressed) on Disk 1 of the source disks that you want to use.

MORE INFORMATION

This behavior can be reproduced as follows:

1. Install for a VGA monitor from 3.5-inch disks.

2. Run SETUP.EXE.

3. From the Options menu, choose Change System Configuration.

4. Choose EGA.

5. When prompted for a disk, try all five 5.25-inch disks. By trying all five disks each time Setup prompts you for a new disk, you can get past several prompts. However, eventually Setup prompts you for Disk 5 and refuses to accept any of the 5.25-inch disks.
