Helix licensed a version of Award Software's BIOS and developed cloaked system and video
BIOSes which executed entirely in protected mode, reducing their real-mode memory
footprint down to 8 KB (instead of 96 KB) and used these as run-time BIOS in
conjunction with their NETROOM memory manager.

As part of their Multimedia Cloaking product, Helix provided cloaked versions of
a home-grown disk cache to replace Microsoft's SmartDrive cache driver.
Helix's CACHECLK could reduce conventional memory usage from 30 KB to just 5 KB.

There was also a product named Multimedia Stacker consisting of Stac's DPMS-enabled
Stacker 4.01 with Helix's above suite of cloaked DOS utilities.

The Logitech DOS mouse driver since MouseWare 6.50 was enabled to take advantage of
CLOAKING as well, thereby reducing the mouse driver's memory footprint visible to DOS
applications from 27 KB to 1 KB.

The MSCDEX Helix variant could reduce conventional memory footprint from 36 KB to 3 KB.

CLOAKING was also licensed to Symantec for their utility suite (Norton Utilities and Norton Antivirus), to Corel for their
CD Creator and Corel SCSI products, and to SMC Networks for their Ethernet drivers.

Hey, you missed the introduction and this final part 😀

Novell's DPMS utility may not be used to temporarily disable DPMS with a DPMS [/]OFF command if those DPMS services are provided by CLOAKING instead of DPMS itself, because Helix's implementation will erroneously not only disallow new drivers to register with DPMS, but completely switch off DPMS services even for already loaded drivers, leading to a system crash.

I found the entire text here.

Thank you for that additional information.

The information I found is scattered within two short notes on old magazine reviews.

A full PDF manual of NetRoom 3.02 would be ideal, if there ever was a such a thing. I only see readme's and some tech docs in the archive and its updates.
It would also be interesting, if it is available somewhere, to obtain the SDK Helix mentions being sent to some development companies.

By the way, it seems they also offered an IBM cdrom driver in a cloaked version (not MSCDEX), but can´t seem to find it within the backups I have at hand.
