Helix Netroom (1995) 2 Utility DOS

Helix Netroom is a memory manager, similar to their Helix Headroom product, but specifically targeted at machines running DOS networking software. Unlike other 386 memory managers that simply page in extra high/UMB RAM, Netroom moves specifically supported TSRs in to an invisible background virtual machine. As a result, large DOS network stacks may be loaded yet not take up any conventional memory needed to run DOS applications. Netroom supported Novell NetWare, Banyan VINES, and LAN Manager networks.
