This update requires you to reboot the machine that has hard drives to be updated 
into the DOS operating system from a bootable USB-Key drive.


=====Format USB-Key as Bootable method=====

Note that this is a two-step process: 
	a) First, the USB-Key must be formatted as a DOS-boot device, unless you already 
           have a key set up that way. 
	b) Then, the utility and other files must be copied to the USB-Key.

Format the USB-Key (if needed):
	1) Using Microsoft Windows Explorer, navigate to the directory where you installed 
           this update (the default installation directory is C:\swsetup\#####).
	2) Double-click HPUSBFormatter.exe and follow the on-screen instructions to install
           the application.
	3) Insert your USB-Key.
	4) ***IMPORTANT***: Back up any important files from your USB-Key at this time. You 
           will need to format your USB-Key in the next few steps, thereby destroying any 
           data on your USB-Key.
	5) From the Start menu, choose Programs, Hewlett-Packard Company, HP USB Disk Storage
           Format Tool.
	6) Choose your device from the drop-down menu. Ensure that "FAT" is selected. Choose 
           to "Create a DOS startup disk," "using DOS system files located at 
           C:\swsetup\#####\usb_files\.
	7) Start the format.
	8) After the format is complete, close the HP USB Disk Storage Format Tool program.

Copy the utility and other files to the USB-Key:
	1) Using Microsoft Windows Explorer, navigate to My Computer.
	2) Note the drive letter of the recently formatted USB-Key (for example: F:).
	4) Using Microsoft Windows Explorer, return to C:\swsetup\#####\.
	5) Navigate to the usb_files\ directory.
	6) Select ALL files in this directory. From the menubar, choose Edit > Copy.
	7) Using Microsoft Windows Explorer, navigate to the recently formatted USB-Key
           (for example: F:). From the menubar, choose Edit > Paste, to paste the files 
           onto the USB-Key at the root folder level.  Select Yes to All for file overwrites.

Your USB-Key is now ready. Now follow the instructions in "Performing the Update," which 
appears later in this document.


=====Use an Existing USB-key=====

This method assumes you already have the DOS operating system on a bootable USB-key and 
only need to copy the utility and other files to the key.  In this case, the files are 
copied to a sub-folder in order to avoid overwriting any of the DOS 
files at the root folder of your bootable medium.

The utility files may be large, so be sure they will fit on your USB-key before starting 
the copy.

Note that HP testing is only done with the version of DOS created by the other methods 
described in this file.  HP cannot be responsible for issues associated with the DOS you 
already have, so if you encounter trouble, consider trying one of the other methods.

	1) Insert your USB-Key into a port on the system where you unpacked this update.
	2) Using Microsoft Windows Explorer, navigate to My Computer.
	3) Note the drive letter of the USB-Key (for example: F:) 
	4) Using Microsoft Windows Explorer, navigate to the directory where you installed
           this update (the default installation directory is C:\swsetup\#####).
	5) Right-click the usb_files\ directory and select Copy.
	6) Using Microsoft Windows Explorer, navigate to the USB-Key (for example, F:. 
	7) From the menubar, choose Edit > Paste, to paste the 
           usb_files\ folder onto the medium. (If you already had a folder with that name, 
           you'll have some renaming to do.)  WARNING:  The usb_files\ folder contains DOS
           system files; be careful not to paste them at the root of your bootable medium!!

Your USB-Key is now ready. Now follow the instructions in "Performing the Update," which 
appears later in this document.


=====Performing the Update=====

NOTE: It is STRONGLY recommended that you perform a system backup prior to installing this update.

NOTE: The firmware update utility cannot upgrade drives that are members of RAID arrays. 
However, it is possible to temporarily take the system out of RAID mode, perform the upgrade 
on the target drives, and then put the system back into RAID mode. Because the firmware upgrade 
does not affect the data contents of the drives, including their RAID membership data, 
the array will operate normally when the RAID mode is restored. In all the supported workstation 
models for this update, the SATA controller mode can be managed via options 
in the BIOS F10 Setup interface. For specific instructions, see the manual for your computer model. 
This mode management does NOT involve deleting or creating RAID arrays.

NOTE: When using the USB key method on the HP Workstation xw9400, it is necessary to disable the 
SATA Option ROM in order for the utility to successfully scan the SATA bus. Some of these 
temporary changes reduce the number of active SATA ports. If many target hard drives are present, 
they may need to be temporarily connected to lower ports for the upgrade.



Once you've created your DOS bootable USB-key, follow these steps:

1. Boot the target system to your DOS-bootable USB-key.

2. Change to the folder containing the utility files, and execute the HP26CE3D.BAT script. 
   The utility will skip any drives that are not targets.  It only updates drives that have
   the affected model string.  It will re-update target drives that already have the correct
   firmware but no harm is done in that.

3. When all drives have been updated, power cycle the system.  It's important to do a 
   complete power cycle to ensure that the drives are fully updated.
