UPDATE: I found a way to update to the New Gateway BIOS 8504.exe for the Vista OS, Here's how I did it :
Reboot your notebook, and tab the F2 key, once you reach the BIOS, you must tap the F9 key to set Defaults, then tap the F10 key to exit, your BIOS will be set to the defalut mode. after you boot into windows vista download , (if you haven't already done so) the 8405.exe to your desktop, right click-on the zip file and run it as Adminstrator, it will then unpack the zip file to the C:\Cabs\8405\Winphlash folder, Double-Click on the Winplash.exe. If you already are running Windows Vista, you must right-click on Winplash.exe and then choose Run as administrator.
In the Phoenix WinPhlash dialog box, verify that Backup BIOS and Flash BIOS with new setting is selected. If the location is already listed as C:\Cabs\8405\Winphlash\BIOS Files\8405.wph, before you click on Flash BIOS. you must 1st click-on the the Advanced tab, and clear all the check marks, the only box that should be checked is, Flash BIOS only if it is newer, click ok and exit the advance tab, then click on Flash, after it flashes, your PC will reboot, then you can check to see if it flashed in the BIOS string to 8405.exe
I didn't notice anything after updating to the new Vista BIOS, but that Vista run a little faster, and windows update, did the rest, and updated, and fixed all of my problem vista drivers, sorry for being so long winded, but I just wanted to share how I flashed to the new BIOS, after about 4 or 5 Fails, I did get something right, so if any of you are having the same problems flashing this new BIOS, I hope this helps you out some, I found this out on-my-own and Gateway didn't have a clue why I couldn't flash to the new BIOS...........kinda makes you wonder just where they get the Tech Support Chat Reps form? they are clueless to about anything, unless they read it outta some service tech white papers, and don't seem to know much, are really care much, about your problems with your PC or Notebook...............LOL
