UniVBE (short for Universal VESA BIOS Extensions) is a software driver that allows DOS applications written to the VESABIOS standard to run on almost any display device made in the last 15 years or so.
The UniVBE driver was written by SciTech Software and is also available in their product called SciTech Display Doctor.
The primary benefit is increased compatibility and performance with DOS games. Many video cards have sub-par implementations of the VESA standards, or no support at all. UNIVBE replaces the card's built-in support. Many DOS games include a version of UNIVBE because VESA issues were so widespread.
According to SciTech Software Inc, SciTech Display Doctor is licensed by IBM as the native graphics driver solution for OS/2.[1]
History[edit]
The software started out as The Universal VESA TSR (UNIVESA), written by Kendall Bennett. It was renamed to Universal VESA BIOS Extensions (UniVBE) in version 5, which supports VBE/Core 2.0, and no longer a freeware.
In version 5.2, it was renamed to Scitech Display Doctor. However, UniVBE continued to be the name used for the actual driver.
Version 6 included support of VBE/Core 3.0, VBE/SCI.
Version 6.5 introduced the ability to use Scitech Display Doctor as wrapper video driver.
Version 7 supports VESA/MCCS, and included Scitech GLDirect, an OpenGL emulator. This version was also ported to OS/2 and Linux (as version 1.0). However, the proposed product has never been widely available. Only pre-releases are available to public. In the Windows SDD prerelease, it included DOS UniVBE driver 7.20 beta, the Scitech Nucleus Graphics driver, GLDirect 2.0 and 3.0 beta. SDD 7 was first released on OS/2 on 2002-02-28, followed by Windows beta on 2002-03-01.
SciTech Display Doctor 7.1 marked the final release of SDD, which was available on OS/2, among other operating systems. However, the Scitech Nucleus Graphics engine lived on as SciTech SNAP (System Neutral Access Protocol) Graphics, SciTech SNAP DDC, and SciTech VBE Test Suite 8.0.[2] Unlike UniVBE, SciTech SNAP Graphics is designed as fully accelerated binary compatible graphic device driver, rather than patching a GPU BIOS to be VESA-compliant.
Display Doctor is no longer supported by SciTech Software. SciTech Display Doctor 5.3a, SciTech Display Doctor 6.53, and UniVBE 6.7 were available on their FTP site, but as of 2009-10-04, the FTP site no longer seems to be available; this seems to be related to the acquisition of SciTech Software by Alt Richmond Inc. 2008-12. Please see the SciTech SNAP article for more details.
One attempt to provide an alternative to SciTech's products was FreeBE/AF, but the last release was 1999-06-27.
Compatibility[edit]
Scitech Gldirect Driver
UniVBE requires a video card with at least 512 KB of memory.
Although UniVBE has supported many controllers, the quality of VESA support decayed in newer incarnations, especially for owners with older hardware. In the case of newer GPUs, the video cards that use them have begun to incorporate rewritable firmware, which allows video card manufacturers to offer better VBE patches than SciTech can supply, especially for cards using Matrox processors.
UniVBE does not add 16-colour screen modes or text modes, but offers an option to reuse those modes with a 'pass through feature.' However, the text mode pass through feature has been broken since the release of SDD 6.
Matrox G-series video cards can only use video modes that utilize at most half of its memory. This is different from the Matrox Millennium, which was documented by SciTech as a hardware flaw.

SciTech SNAP (System Neutral Access Protocol) is an operating system portable, dynamically loadable, native-size 32-bit/64-bit device driver architecture. SciTech SNAP defines the architecture for loading an operating system neutral binary device driver for any type of hardware device, be it a graphics controller, audio controller, SCSI controller or network controller. SciTech SNAP drivers are source code portable between different microprocessor platforms, and the binary drivers are operating system portable within a particular microprocessor family.
SNAP drivers were originally developed for Intel 386+ CPU with any 32-bit operating system or environment supported on that CPU. With the introduction of SNAP 3.0, native binary SNAP drivers are available for 32-bit PowerPC CPUs and 64-bit x86-64 CPUs.
On 2002-08-27, SciTech Software, Inc. announced the intention to release the Scitech SNAP driver development kit.
On 2006-11-16, SciTech Software, Inc. announced that it has ceased further development of its SNAP device driver technology in favor of a new line of web and business logic technologies. SciTech also announced that it would begin looking for a buyer for SciTech SNAP.
In December 2008 Alt Richmond Inc. closed the acquisition of SciTech Software’s SNAP technology. The plans of SciTech Software in 2008 to create OpenSNAP, an open source version of the driver technology, are therefore no longer an option unless Alt Richmond decides to pick this up.[1]
In May 2015 Arca Noae, LLC announced that they have reached an agreement with Alt Richmond, Inc. to license the source code for SNAP Graphics for OS/2.[2]

Relationship with Scitech Display Doctor[edit]
SciTech Display Doctor 6.5 included a replacement video driver for Windows 95 or higher, which works with any hardware supported by SDD. In SDD 7, the driver was renamed to Scitech Nucleus Graphics driver. The Nucleus Graphics driver was later incorporated into SciTech SNAP Graphics. In SNAP 3, Nucleus was renamed to SNAP.
SciTech SNAP Graphics version 2 also included VBETest/Lite - VESA BIOS Extensions (VBE) Compliance Test version 8.00. It was later removed in SciTech SNAP Graphics 3.
In SciTech SNAP 3 for DOS, most of the OpenGL tests from SciTech Display Doctor 7 beta can be found in GACtrl Driver Control Center.
Windows version of Scitech SNAP Graphics maintained the user interface found in SDD 7 beta.
SciTech SNAP Graphics[edit]
It is the first product for the SciTech SNAP line, which provides accelerated graphics.
SciTech SNAP Graphics has been ported to DOS, OS/2, Microsoft Windows (CE, NT, 2000, XP), QNX, SMX (the SunOS/Solaris port of MINIX), Linux, On Time RTOS-32, Unununium OS operating systems. Supported hardware included video processors from 3dfx, 3Dlabs, Alliance Semiconductor, AMD (Geode GX2), ARK Logic, ATI, Chips & Technologies, Cirrus Logic, Cyrix, IBM, InteGraphics, Intel, Matrox, NeoMagic, Number Nine, NVIDIA, Oak, Philips, Rendition, S3, Sigma Designs, Silicon Motion, SiS, Tseng Labs, Trident, VIA, Weitek, as well as any video card supporting VBE 1.2 or higher.
Although SciTech SNAP Graphics does not offer standalone VBE driver, SNAP driver accelerates applications using VBE calls via SciTech SNAP Graphics driver. SNAP Graphics for Windows can also accelerate VBE 3 calls, if DOS programs is run in Windows DOS box.
Spin-off products[edit]
- SciTech SNAP Graphics ENT
- SciTech SNAP Graphics ENT/BC with DPVL support (SciTech SNAP Graphics VESA DPVL)
- SciTech SNAP Graphics IES
Personal Edition[edit]
SciTech also offer SciTech SNAP Graphics 'PE' (Personal Edition) under the My SciTech site, which allows registered users to download a SNAP driver of hardware and operating system specified by users. Each user account can download two drivers per week. The driver generated by the service can be run for six months.
In Scitech SNAP Graphics PE, tools GACtrl, GAMode, GAOption, GAPerf DOS tools are included. The GLDirect tests are not included in Windows driver.
SciTech SNAP Audio[edit]
Similar to Scitech SNAP Graphics, it provides OS-independent audio drivers. It has been ported to Windows NT 4.0. Supported hardware include AC'97 and Intel HDA, but HDA does not support modem function.
SciTech SNAP DDC[edit]
Driver Download For Windows 10
It is designed to provide easy access to an attached display in order to program it directly via I²C or simply to read the monitor's EDID record.
