ENHANCEMENTS: 
The following enhancements have been added since BIOS version 01.07 (SP38380) 
was released:
- Adds microcode and BIOS support for future processors.
- Adds a number of changes to hardware initialization sequences. These may 
further reduce rare instances of boot failure.
- Adds the ability to store and retrieve any errors detected by the processor 
or chipset. 
- Increases the completion timeout value for PCI devices. This allows certain 
PCI devices to function reliably during periods of heavy system load.

The following enhancements have been added since BIOS version 01.01 (SP37878) 
was released:
- Enables an additional CPU power saving mode in the Computer Configuration 
Utility (F10). The new mode is enabled when Idle Power Savings is set to 
"Extended."
- Adds BIOS support for additional CPU speeds.

FIXES: 
The following fixes have been made since BIOS version 01.07 (SP38380) was 
released:
- Fixes an issue that prevents the system from completing Power-On Self-Test 
(POST) when certain graphics cards are installed in both slots 1 and 3.
- Corrects an issue that causes certain DOS programs to fail when accessing 
serial ATA (SATA) optical storage devices while the SATA controller is in 
Advanced Host Controller Interface (AHCI) mode.
- Corrects the Multi-Processor Specification (MPS) table to properly describe 
the embedded network interface controller and x1 PCIe slot.

The following fixes have been made since BIOS version 01.01 (SP37878) was 
released:
- Adds new CPU microcode updates to resolve a processor erratum.
- Corrects an issue that could have reduced the reliability of Advanced 
Configuration and Power Interface (ACPI) save-to-RAM cycles in certain 
situations. 
- Fixes an issue that prevented the correct messages from being displayed when 
enabling Drive Lock in the Computer Configuration Utility (F10).
- Fixes an issue that prevented the maximum CPU temperature from being 
correctly reported through the Microsoft Windows Management Interface (WMI).

PREREQUISITES: 
None

INSTALLATION INSTRUCTIONS: 
LINUX USERS: After downloading the SoftPaq file, verify that the SoftPaq file 
has a .tgz extension. If it does not, change it to .tgz. Some browsers 
automatically rename the file with a .tar extension, which makes the SoftPaq 
unusable. 

1. Download and extract the .TGZ file. For example, to extract the contents, at 
console prompt type (where ''filename'' is replaced by the name of the file to 
be extracted): 
''tar -xzvf filename.tgz''

2. For more information about flashing the system BIOS, see the README text 
file that is provided in the SoftPaq.
