What if I was to find another Gateway PC that is running the Intel EV91510A.15A.0123 BIOS? I could then make a copy of the BIOS running on that PC and then apply it to my Gateway 5300S.
There are other models of the Gateway PC that are running the Intel EV91510A.15A.0123 BIOS. Here are just a few I have identified:

Gateway 3250S
Gateway 507GR
Gateway 5200XL

From many of the posts that I have read, it is better to use the manufacturers flash utility instead of a third party utility. In this instance, instead of using UniFlash, I should use Intel's IFlash. I have plenty of documentation on how to use IFlash to apply a BIO file in a flash update. What I do not yet have is how to CREATE a BIO file for use by the IFlash utility.
I have here the command line documentation for IFlash:
/////////////////////
Intel Flash Memory Update Utility Part 643643-051
GUI-mode options:
/m - Monochrome display /b - Use BIOS video calls
/t - Use EGA/VGA line count /n - Do not use pointer device
Command-line mode options:
/h - Help (this text)
/q - Quiet mode; errors only, and no prompts
/qb - Quiet mode; No beeps
Standard options:
/r - Force reboot after update /@ - Use override file
/f - Force CMOS defaults next POST /d - Verbose debugging output
/p pathname - Program FLASH device with contents of 'pathname'.
/nr - No reboot when complete (SMI flash method)
/rb - Reboot before update (non-SMI flash method)
Special Operations:
/v pathname - Verify current flash with contents of 'pathname.'
/x pathname - eXamine flash header of 'pathname'.
/sX pathname - Save resident flash area to 'pathname' (or 'vvvv'BIOS)
X = { 'B'IOS, 'L'anguage, 'U'ser, 'R'ecovery } area.
/ae - Erase OEM CMOS Defaults.
/ac - Copy Custom CMOS Defaults into the OEM CMOS Defaults.
/af - Force OEM CMOS Defaults next POST.
/ag pathname - Get OEM CMOS Defaults to 'pathname'.
/as pathname - Set OEM CMOS Defaults with contents of 'pathname'.
/ew pathname - Write BMI settings with contents of 'pathname'.
/er pathname - Retrieve BMI settings to 'pathname'.
/md - Load default modules only (like recovery).

It looks like 'IFlash /sB'. I am not sure. I will continue looking.
I also am not certain if it is better for me to do the 'Instructions for Recovery BIOS update':
http://www.intel.com/support/motherboar ... 60.htm#usb
Using this method, I simply put only the BIO file on a diskette, remove the BIOS Configuration Jumper, and boot with the diskette in the diskette drive. The PC will read the BIO file and apply the update.
Or, should I do the IFlash command line option:
http://www.intel.com/support/motherboar ... 023358.htm
Using this method, I boot to DOS and, at the command line, enter:
IFLASH /PF XXX.BIO
Based on what I have been reading, it appears the most thorough method is going to be Recovery BIOS update method. Either way, I just need to learn how to create the .BIO file from another PC first.
I would appreciate any feedback/input that I can get on this.
