These DVO ports were multiplexed via the AGP connector and could be used by an ADD card. The i8xx used DVO (Digitial Video Out) ports to talk to external chips (TMDS, LVDS and TV-Out). The integrated graphics functionality is disabled when an external AGP card is detected. The i8xx chipset supported AGP graphics cards. Post the GM series things can be a bit murky, but normally a GMS version of the chip can be released which is also mobile targeted but with maybe less power or more features Later a mobile targeted version is usually released tagged with a GM (i915GM and 945GM). These are normally the desktop targeted graphics chips. The chipsets containing integrated graphics always seem to be have a G in the name. The chipsets also commonly allow for an external graphics adapter to be used in-place of the integrated functionality (AGP or PCI-E). Intel produces motherboard chipsets with and without integrated graphics functionality. The Intel chipsets can be split into 4 categories at this stage. Here is an attempt to collect information about some IntelRegisters for those chips. Programmer's Reference Manuals for both generations of the i965 family are available on the Intel driver development site.įor the other chips, have a look at the datasheets for various versions of the Graphics and Memory Controller Hub (eg. There are complete Programmer's Reference Manuals including register descriptions for the i810 and the i815. Specifications for a few Intel chipsets are publicly available on its developer site.

Open-source 3D drivers for SGX chipsets, nor are there Poulsbo/Moorestown/Cedarview-based SGX chipsets. Brief-lived successor to the i740, and may in fact be identical to the i810. The i740 appears to be the i810 minus multitexturing and anisotropic mipmap filtering, with slightly different register locations. The datasheet is available here, but this is a feature list only and is not useful for programming a DRI driver. Intel claimed to have a Software Developer's Manual (order number 290617) available for this chip, but it is not posted on the website anywhere.
