Version History:

This release was the first version from any OEM or retail source that broke the 32MB hard disk partition barrier - a DOS first. Version 3.31 supported native partition sizes (both physical and logical) up to 512MB without the aid of a device driver. These partitions were only accessible from Compaq's release of 3.31 - any previous 3.3x release on the market would identify them as Non-DOS partitions using FDISK. Like its 3.3x cousins, this release added support for 1.44 high density floppy drives and national language support.
