Adds an Intel errata patch for the microprocessor firmware to address a potential issue that might cause a system to exhibit erratic behavior such as a system hang, reboot, blue screen, or Kernel Panic in Linux, and may also cause in-progress system operations (e.g., file, I/O) to fail. The possibility of this behavior is believed to be limited, but we strongly recommends that customers install this update as soon as possible to prevent the possibility of the issues listed above.
See Retain Tip H181898 for more details on this issue. The IDs of the affected microprocessors are 0F29, 0F33, and 0F34.
Note: If you want to apply this processor patch without updating the rest of BIOS, refer to the "FLASHING BACK TO AN OLDER LEVEL OF BIOS" topic in the README.1ST file contained in this BIOS update package
Determining the processor ID ---------------------------- There are several ways to determine the ID of the processor:
Go to BIOS setup (hold down the F1 key and power up the system) and look under the "Advanced" tab. (The processor ID is about 1/2 way down the screen.)
Use the Microsoft "System Information" tool. Go to the task bar and click through the following selections: Click Start, select Programs, select Accessories, select System Tools, then click System Information.
The first screen displayed with this tool has processor information. For example, a F24 ID processor will have the following entry. (The "F" is translated to a "15" by this tool.) "Processor x86 Family 15 Model 2 Stepping 4 GenuineIntel .."
DMI information. The processor ID is presented in the DMI (Desktop Management Interface) Type 4 structure. There are various tools (DMI browsers) available to view this information.
