Can I use the new Intel Embedded Graphics Drivers in conjunction with an older IEGD video BIOS?
Although not always required, it is generally a good idea to upgrade both the VBIOS and driver when an update occurs. We only test using the latest of both VBIOS and driver so there may be surprises that occur. Often there are code changes that you will want. Sometimes there are new features that require both to be updated. If you see a negative change in operation of the driver after updating just the driver and not the VBIOS, it is a good idea to try the new VBIOS also to see if there is an unexplained interaction between the old and new code.
