• Replace eight capacitors by smaller type in order to avoid collision with PCIe x1 card, PCIe x16 card and PCI card (Note: This smaller “longlife type” has not been available before).
• Update of System Monitoring Controller Firmware for enhanced reliability and functionality:  
  • New option: Timeout for “FanFail” can be configured via register  
  • New option: Fan speed changes can be limited (configurable via register)  
  • avoid insane error messages due to sporadic monitoring communication conflict (e.g. Fan error although fan is not installed)
• Frontpanel Audio Jack Detection improved (avoids possible sporadical detection problem with HDA frontpanel after S3 or S4).
