| 1 | Codes Names - these are not offically documented by Intel, and I have done my best to make them accurate. If you know better, please let me know. The only place they are usually found is in the BIOS file but not with the latest MBs. |
| 2 | Virtually all Intel motherboards are manufactured with multiple options, varying cache sizes, different connectors, with or without video or audio. Just because this reference says something is available does not means a specific MB has it fitted. |
| 3 | This information was originally abstracted from the now obsolete Intel FaxBack service - UK 01793 496646, USA 1-800 628-2283 or 916-356-3105, and ftp.intel.com, and now mostly from http://www.intel.com/design/motherbd/ |
| 4 | Some MBs have been through several revisions, to support faster processors. Early Zappas are max 90Mhz, PBA 638995, 641525, 639379 are 100MHz, -606, -607, - 806, -808 and above are 120MHz. Only Endeavors with Socket 7 support 150/166MHz. |
| Only Rhinestone with a voltage regular and heat sink next to the socket 7 support MMX processor. Only Tuscon MBs with AA numbers 677269-603 and 677270-60x support the 233MHz MMX processor. Likewise only the latest revisons of most MBs support MMX. | |
| 5 | Triton does not support SIMM parity checking, so only 32-bit SIMMs are needed. 36-bit SIMMs may be used, but have no advantage. |
| 6 | Most Pentium motherboards support three bus speeds, 50MHz (Pentium 75), 60MHz (Pentium 90, 120, 150, 180), and 66MHz (Pentium 100, 133, 166, 200). A bus speed of 66MHz requires 60ns EDO SIMMs. |
| 7 | SIMMs should have tin lead pads, not gold. |
| 8 | Endeavour and Atlantis support two types of cache, 256K write back SRAM chips soldered to the MB and a plug-in CELP module with 256K or 512K async or pipelined burst cache. |
| 9 | Atlantis has on-board Mach64 SGVA with 1 MByte memory. This can be upgraded to 2 Mbyte, with two 256K x 16 60ns SIMMs. |
| 10 | Atlantis motherboard has also been called Endeavor II, when supplied without on-board SGVA. |
| 11 | Most Intel motherboards are available through authorised distributors. except those indicated as OEM which are supplied to original equipment manufacturers only |
| 12 | Intel does not publish BIOS revision levels for many OEM MBs, so these are inaccurate. |
| 13 | Older Pentium motherboards support Pentium OverDirve processors with MMX technology (which includes a voltage regulator), the maximum speed varying depending upon the maximum speed of the MB and will fit either Socket 5 or 7 MBs. |
| 14 | LPX and NLX low profile MBs have expansion sockets on a riser card. The riser card may vary, so it's not possible to define the number of PCI and ISA slots for such MBs. The NLX riser is a new design and also contains floppy, EIDE and other connectors. |
| 15 | Some motherboards are indicated as being for a server (OEM). These products are normally only available as a complete server chassis, but are included here since the MBs are otherwise unique. |
