Windows 98 SE build 2120

Windows 98 SE build 2120 is an internal build of Windows 98 Second Edition. It should not be confused with Windows 98 build 2120, which was a build of the planned Service Pack for the original release of Windows 98.

Source directory
Some copies of this build have the source directory name in lower case instead of upper case, which makes the directory inaccessible under MS-DOS. To install with such a copy, you need to either upgrade from an older build, copy the installation files to the hard disk beforehand, or create a new disc image with the correct directory name. A fixed copy is available on BetaArchive which doesn't have this problem.

Missing CAB
is missing, so WaveTop TV cannot be installed, as  is split across CABs 23 to 26.
