Personal NetWare

Netware Lite contained a unique serial number in the EXE files that prevented running the same copy on multiple nodes within a single network.

This basic copy protection was easily circumvented by comparing files from different licenses and accordingly editing the serial number bytes.

The ODI/VLM 16-bit DOS client portion of the drivers now supported individually loadable Virtual Loadable Modules (VLMs) for an improved flexibility and customizability, whereas the server portion could utilize Novell's DOS Protected Mode Services (DPMS), if loaded, to reduce its conventional memory footprint and run in extended memory and protected mode.

[3][5] The Personal NetWare 1.0 product saw five maintenance upgrades for the Western issues and two for the Japanese versions as well as various comprehensive updates to the corresponding VLM client driver suite (1.0, 1.1, 1.20, 1.21) as part of the Novell Client Kit for DOS & Windows up to November 1996 in the Western world and up to April 1997 in Japan.

[clarification needed] Later, Personal NetWare was bundled with full versions of Caldera OpenDOS 7.01, DR-DOS 7.02 and 7.03 between 1997 and 1999; however, these bundles were delivered with the same Personal NetWare files shipping with Novell DOS 7, not the upgraded files, which had been made available for download by Novell since 1994.
