(Critical update) Flash BIOS update (DOS update package) - IBM eServer xSeries 255

Download Description

Severity: Critical

Version 1.08

• This BIOS flash image update contains an Intel errata patch for the microprocessor firmware. It addresses a potential issue which might cause a system to exhibit erratic behavior such as a system hang, reboot, blue screen or Kernel Panic (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 IBM strongly recommends that customers install this update as soon as possible to prevent the possibility of the issues listed above. See Retain Tip H181994 for more details on this issue. - Updates to support RDM.
