SOFTPAQ NUMBER: SP29491 PART NUMBER: 339081-005 FILE NAME: SP29491.EXE TITLE: Systems ROMPaq Firmware Upgrade Diskette for HP ProLiant ML350 G4 Servers. VERSION: 4.04A LANGUAGE: English CATEGORY: ROMPaqs DIVISIONS: Systems PRODUCTS AFFECTED: HP ProLiant ML350 G4 OPERATING SYSTEM: ALL SYSTEM CONFIGURATION: N/A PREREQUISITE: N/A EFFECTIVE DATE: January 12, 2005 ELECTRONIC DISTRIBUTION ALLOWED: Yes SOFTPAQ UTILITY VERSION: 2.X SUPERSEDES: SP29372 DESCRIPTION: This release provides updated system ROM images for the latest maintenance releases of HP ProLiant ML350 G4 Servers. New Features - ProLiant ML350 G4 ROM D17 (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 ML350 G4 ROM D17 (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. Previously, the System ROM would always enable this feature regardless of the RBSU setting. 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 SP29491.EXE. 3. From that drive and directory, execute the SoftPaq file: SP29491 [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 SP29491.EXE if you wish. Copyright 2005, Hewlett-Packard Company. All rights reserved.
