... Specification Changes are modifications to the current published specifications. These changes will be incorporated in the next release of the specifications. Errata are design defects or errors. Errata may cause the Intel deviate from published specifications. Hardware and software designed to be used with any given stepping must assume that all errata documented for that stepping are present on all devices. ...

... Implication: If the Conditions stated above are met the GMCH will display incorrect data on the screen resulting in some lines of color on the screen. Workaround: Do not run overlay in 4:2:0 or 4:1:0 modes when the surface is in linear memory and either horizontal or vertical mirroring is turned on. Status: No Stepping Fix Specification Update ® Intel 82810 GMCH Description 11 ...

... Intel 82810 GMCH Blit Data Corruption 3. Problem: During a blit, the last QWord of data on a scan line will substitute the second to last QWord of data when clipping is enabled. This condition takes place when the last QWord of data is not full of pixel data. Implication: Some of the scan lines will have the last pixels, based on the color depth, corrupted. For 24bpp the last 2 pixels can be corrupted, for 16bpp the last 3 pixels can be corrupted and for 8bpp up to the last 7 pixels can be corrupted ...

... Problem: A2 stepping of the Intel aligned data on Intel memory mapped I/O, and PCI space. No impact on cycles to memory and write combined AGP space. Implication: Results in data corruption that may lead to a system hang. No Intel ® on Intel 810 chipset platforms. Workaround: None Status: Intended to be fixed in the A3 stepping. See Summary Table of Changes for affected product(s) and steppings ...

... Implication: The result could be a hang of the parser state machine or incorrect setting of the state variable in 3D. The only known application that uses the interrupt priority ring is the stretch-blit operation. Intel drivers associated with the 82810 do not use this process. This process is used by DVD software. ...

... Win2K (32 applications). Validation activity included the use of automated and manual testing of over 400 applications, stress test software, and benchmark software. Due to the specific sequencing of events necessary to create the failure, Intel and major OEMs were unable to recreate the problem during any testing described above. ...
