New Features -	
 				 
        ProLiant BL20p G3 ROM I08 (12/02/2004)
        ============================================
	   	   
           Added new RBSU feature called Dynamic Power Savings Mode
           (Auto) under the ProLiant Power Governor option in Advanced
           Options. When this feature is enabled, the System ROM will
           modify the processors power state based on the systems
           workload. When processor intensive workloads are being run,
           the processor will run in its highest power and performance
           state. When the processor is doing little work, the
           processor will run at a lower power and performance state.
           This allows the system to reduce its overall power usage
           while having minimal or no effect on performance. This
           feature works independent of the operating system and
           requires no additional drivers or OS support to operate.    
             

Problems Fixed -                        
		
        ProLiant BL20p G3 ROM I08 (12/02/2004)
        ============================================
	   
           Updated the support code for all Intel Xeon processors
           supported by this system. This addresses a critical issue
           in all Intel Xeon Processors with 800 MHz System Bus.  All
           customers should update their System ROMs to address this
           processor issue.

           Updated to resolve issue where systems with exactly 4 Gbytes
           of memory will not make all 4 GBytes available to the
           operating system.  Typically, the system will report 3.5
           Gbytes as being available to the operating system even
           though 4 Gbytes of DIMMs are installed.  Various devices
           in the system, including embedded PCI devices, plug-in PCI
           devices, and PCI-Express devices, must have their memory
           mapped below 4 Gbytes. With previous ROM versions, the
           memory space used by these devices was lost. With the new
           version of the System ROM, the memory which was previously
           lost will be remapped to above 4 Gbytes. Thus, all memory
           will be available to the operating system, but some of that
           memory is only addressable above 4 Gbytes. To access 
           memory above 4 Gbytes, the operating system must be
           configured to enable Physical Address Extensions (PAE) Mode.
           Consult your operating system users guide on how to enable
           PAE mode.

           Updated to resolve issue where the No-Execution Memory Mode
           option in the ROM Based Setup would not function properly.
           When disabled is selected the System ROM may still enable
           this feature.

           Updated to resolve intermittent issue that occurs on certain
           system reboots in which interrupts will not be distributed
           evenly among installed processors. Typically, all interrupts
           would be directed to one processor when this problem occurs.
           This condition can result in less than optimal performance.
	     		 		    
HOW TO USE:


1.  Obtain a formatted 1.44 MB diskette.

2.  Download the SoftPaq to a directory on your hard drive and change to that directory.
The file that is downloaded is SP29490.EXE.

3.  From that drive and directory, execute the SoftPaq file:
SP29490 [ENTER]
You will be prompted to place the formatted 1.44 MB diskette into a diskette drive to
create diskette.

4.  After the diskette is created, you may delete the downloaded file
SP29490.EXE if you wish.
