Intel D845PEBT2 Specification Update - Page 11

Intel Desktop Board D845PEBT2 Specification Update ERRATA 1. Onboard Serial ATA (SATA) Hard Disk Drives (HDD) Will Perform Slowly Prior to Loading the SATA Driver For the Microsoft Windows* Operating System PROBLEM: Serial ATA HDD software operations, prior to loading Microsoft Windows SATA drivers, results in slower SATA HDD performance. IMPLICATION: If a user attempts to boot to an operating system other than Microsoft Windows or attempts to use software prior to loading the SATA driver for a Microsoft Windows operating system on a SATA HDD, drive performance will be slow. WORKAROUND: None. STATUS: This erratum may be fixed in a future BIOS revision. 2. Fan Control Defaults Incorrectly Set in BIOS for Onboard Hardware Management ASIC PROBLEM: Default BIOS settings on desktop boards that implement the Intel Precision Cooling Technology fan control are incorrect, which could result in improper system cooling. IMPLICATION: The maximum front and rear system chassis fan speeds are limited to 30% of maximum, irrespective of the actual chassis temperature. Under certain circumstances, this fan speed limitation may not provide adequate system cooling. NOTE: The CPU fan is not controllable by the desktop board and is not directly impacted. WORKAROUND: Disable fan control by changing the 'FAN CONTROL' setting to "Disabled" in the BIOS setup menu under the 'ADVANCED' tab, 'FAN CONFIGURATION' menu. This will allow the system fans to run at full speed, which will allow maximum system cooling. STATUS: This erratum was fixed in BIOS revision BT84520A.86A.0010.P03. 3.
