Windows 98 build 1400

Windows 98 build 1400 is a Beta 1 build of Windows 98, released on 1997-02-25. It includes several updates to Windows Setup. An "Enable Sound" checkbox is included, however, the functionality is not yet in place. The sidebar layout is now used in the second stage of installation, and Setup now performs the final stage of configuration without a reboot. Internet Explorer integration is also new in this build, changing some core UI functionality. WINVER is labeled as "About Internet Explorer", rather than "About Windows". The Start Menu banner text has been replaced, now reading "IE4 Preview Release".

ACPI
This build has poor ACPI support, thus it will usually crash in the second stage of setup. To fix this, disable ACPI in the VM or machine.
