        3.0   Installation and Setup Instructions

              The procedure to update the POST/BIOS is as follows:

              3.1  Insert the "IBM Intellistation Z Pro POST/BIOS
                   Flash Diskette" into drive A.

              3.2  Start up or restart your IBM system.

              3.3  The system will boot off of the diskette.

              3.4  You will then be asked if you would like to save the current
                   code to a diskette.  If you select 'Y', you need to name
                   the file to be saved. The file will be saved on the diskette.
                   If you select 'N', the utility will continue to the next step.

              3.5  At this point, you will be asked if you would like to continue the
                   POST/BIOS flash update. If you select 'Y', the system will update
                   the flash ROM with the new code.  When this is complete you will be
                   prompted to remove the diskette and hit 'F1' to reboot the system.
	
	      3.6  On the first system boot, after updating the BIOS, select the Setup Utility 
		   with the F1 key; then, select the "Load Default Settings" option.
		   Select the "Save Settings" option, and hit 'y' to save.  Then, select
                   "Exit Setup" to exit the utility, and, finally, accept the displayed
                   'Y' option under "Save and exit the setup utility?"
