OPERATING SYSTEM(S): 
Microsoft Windows XP

LANGUAGE(S): US (Global)

ENHANCEMENTS: 
 - Enhances display of network adapters in F10 Setup to include the vendor name.
 - When restoring F10 settings from diskette, the BIOS now has the user confirm the 
   “save changes and exit” before saving device security settings.
 - Adds an option to F10 Setup to allow the integrated audio to be enabled even if a 
   PCI audio card is present. Previous BIOS versions disabled the integrated audio 
   automatically, without an option to enable it again if a PCI audio card was detected,
   in order to prevent resource conflicts between the PCI and integrated audio devices.
 - Enhances the F10 Setup “Save to Diskette” and “Restore from Diskette” features to 
   prevent bad diskettes from causing a system lock-up.
 - Adds a type-11 record to the SMBIOS tables for use by service.
 - Adds support for certain Samsung USB keyboards.
 - Adds support for Compaq iPaq Home Phone Network Adapter (HPNA).
 - Adds support for Northwood Pentium 4 processors (specifically B0 stepping)
 - Adds support for core chipset MCH B0.
 - Adds support for new DDR platforms.

FIXES:
 - Corrects the reporting of L1 and L2 cache type in the SMBIOS structure (information only).
 - Corrects the reporting of the L1 cache size in F10 Setup, from 8KB to 20KB to reflect 
   the full L1 cache size in the Pentium 4 (information only).
 - Corrects the saving of the boot order information when saving settings from F10 setup to 
   diskette when a USB boot device is set as “disabled” in the boot order. The previous BIOS 
   version would save an invalid string in the settings file under this condition.
 - Makes a change to BIOS to correctly report the memory map of the EBDA in all cases.
 - Corrects the PCI resource settings when installing two SCSI devices of type Adaptec Dual 
   Channel Ultra160 SCSI Card PCI Model AHA-39160 and Adaptec SCSI Card 29160 Ultra160 
   64-bit PCI.

on-screen instructions to build the ROMPaq diskette.

4. After the diskette has been created, you may delete the SoftPaq file
downloaded in step 2.  NOTE: ROMPaq disk can be recreated by running QRST5.EXE

5. Place the newly created diskette in the A: drive of the computer to be
upgraded or restored and cycle system power to boot from the ROMPaq diskette.
