Originally, SLI-capability of motherboard checked by complex crypted routines in videocard driver, and thus bypassing this check was quite hard earlier. There only few old drivers present, which support SLI on non-NVIDIA chipsets, like 84.xx and 81.xx drivers made few years earlier. Now things changed, with officially SLI-capable Intel X58 chipset. In the case of Intel X58 motherboards, checking SLI support by driver was developed with a simplified scheme, which uses text strings and identifiers for all present and future X58-boards. Later P55 are also was added to support similar SLI certification procedure.

Modification tools described here can be used to force the NVIDIA graphics driver to detect supported chipset «Intel X58», regardless of what the real hardware chipset present in system. After receiving the identification of a "X58" chipset, videocard driver checks for the correct certificate from BIOS to check "compatibility" with SLI tech, which should be located in the system table DSDT, which is a part of ACPI. Initially, the data tables are loaded from the computer's BIOS, but later, if BIOS wasn't changed, used from the regular OS registry entry by Windows.

For today, after long time of tool development and research, we got latest version of patch available in beta-status for public testing. These modifications are for education purposes and are provided "AS IS", without any warranties. We (xDevs.com project and developers of SLI patch) cannot be held responsible for any errors, failures or data loss during this procedure, make sure you have backed up all critical data before trying this mod. So, before we give all instructions, please note that these operations interact with the PC's hardware at low level, so in case your PC fails, data loss or any other damage occur responsibility rests solely on you. . However, on all the systems we have tried, we have had no errors, all passed without any major mistakes.

Because of difference of OS kernels and HAL library in every os, every SLIpatch tool hardcoded and dedicated only for specific operating system type and version. Using wrong SLIpatch will cause OS unstable or even damaged. Be aware to use only proper tool version.

This method and tools has been successfully tested and implemented for following operating systems:

Microsoft Windows XP 32-bit
Microsoft Windows XP 64-bit
Microsoft Windows Vista 32-bit
Microsoft Windows Vista 64-bit
Microsoft Windows 7 32-bit
Microsoft Windows 7 64-bit
Microsoft Windows 2008 R2
