- SciTech SNAP
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 2002-8-27, 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.
Relationship with
SciTech Display Doctor 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.
ciTech SNAP Graphics
It is the first product for the SciTech SNAP line, which provides accelerated graphics.
SciTech SNAP Graphics has been ported to
MS-DOS ,OS/2 ,Microsoft Windows (CE, NT, 2000, XP),QNX ,SMX ,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 supportingVBE 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.
pin-off products
*SciTech SNAP Graphics ENT
*SciTech SNAP Graphics ENT/BC with DPVL support (SciTech SNAP Graphics VESA DPVL)
*SciTech SNAP Graphics IESPersonal Edition
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 2 drivers per week. The driver generated by the service can be run for 6 months.
In Scitech SNAP Graphics PE, tools GACtrl, GAMode, GAOption, GAPerf DOS tools are included. The GLDirect tests are not included in Windows driver.
ciTech SNAP Audio
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.
ciTech SNAP DDC
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'sEDID record.External links
