Fixes & Enhancements
Fixes:
Corrected an issue where L1 Cache Operational Mode is reported incorrectly as Write-Through in SMBIOS. All L1/L2/L3 should be Write-Back .
Corrected an issue where a complex sequence of internal processor events may result in unexpected page faults or use of incorrect page translations if EPT (Extended Page Tables) is enabled. Due to this error, a guest may crash or experience unpredictable system behavior.
Corrected an issue where BIOS cannot read Extended PCIe Capabilities on devices other than CPU1 using UEFI interfaces.
Corrected an issue in the IHV SCT test where the responses to the invalid passing parameters are incorrect.
Corrected an issue in System Setup where the system was truncating device names in the Device Settings page when Console Redirection was active.
Corrected BIOS/iDRAC Console Redirection interface issue that could change BIOS Setup settings to defaults.
Enhancements:
Updated Intel processor and memory reference codes to Rev V2.00.00.05.
Updated Intel Xeon processor E5-2600 V2 product family microcode to 427.
Updated Intel chipset configuration compliant with latest BIOS specification updates Rev (2.0.7).
Updated the maximum supported memory speed to 1866 MT/s for 32GB LRDIMMs in 2 DIMM per channel configurations when operating at 1.5V for supported Intel Xeon E5-2600 V2 family of processors. Note that 1866 MT/s capable LRDIMMs are required to run at 1866 MT/s.
Updated iDRAC HII configurator UEFI driver to v1.60.60.02.
- In the iDRAC Settings Utility, on the iDRAC Settings page, the name OS to iDRAC Pass Through is changed to Communications Permissions.
Set Mellanox PCIe devices Max_Read_Request_Size as 4096 bytes to improve performance.
