End of Interactive Support
Intel is announcing the end of interactive support for the Intel® MU440EX Motherboard. See the End of Interactive Support Announcement for details.
Different versions of the Intel® MU440EX Motherboard provide different processor support. A small barcoded label, similar to the diagram shown below, can be found on the component side of the motherboard. The numbers following the letters "PBA" or "AA " can help identify the version of your motherboard.  Also note whether your BIOS version is 4M4UE0X1 or 4M4UE0X3. After locating the PBA or AA number and BIOS version, consult the tables below to determine which processors are supported by that motherboard: Supports only Intel® Celeron® processors 266, 300, 300A, 333, 366, and 400 MHz:
| AA Number | PBA Number | BIOS Version | | 698722-402 | 695747-402 | 4M4UE0X1 | | 702993-402 | 695747-402 | 4M4UE0X1 | | 702999-402 | 695747-402 | 4M4UE0X1 | | 698722-403 | 695747-403 | 4M4UE0X1 | | 702993-403 | 695747-403 | 4M4UE0X1 | | 702999-403 | 695747-403 | 4M4UE0X1 | | 698722-404 | 695747-404 | 4M4UE0X1 | | 702993-404 | 695747-404 | 4M4UE0X1 | | 702999-404 | 695747-404 | 4M4UE0X1 | |
Supports both Pentium II processors with 66 MHz Front Side Bus and Intel Celeron processors 266, 300, 300A, 333, 366 and 400 MHz:
Note 1: In the table below, support is available beginning at the -xxx level shown and any subsequent -xxx revisions.
Note 2: Support for Intel Celeron processors 300A, 333, 366 or 400 MHz requires either BIOS 4M4UE0X1.86A.0011.P10 or later or BIOS 4M4UE0X3.86A.0004.P03 or later--depending on which version (4M4UE0X1 or 4M4UE0X3) matches your board.
