*Guessing* Don't have an 8886 in to run the bios upgrade.
You probably don't need the FP.EXE file, just flash.exe and the .bin.
You can creat a startup disk with Windows XP by sticking a blank disk in, right click the drive under my computer and go to the option format and check to create startup disk.
After you create the start up disk, add flash.exe and 888ER200.bin to the disk from the file you download and unzip.
Reboot and jump into the bios (CTRL/ALT/S) and set it to boot from floppy, save and exit.
Boot to the A: prompt and type "FLASH.EXE" and it should run the flash program.
The program should ask you if you want to save the old bios program and you say yes and name it. I usually name it "OLD". If there's not enough room for it, you can dump off some of your bootup files that aren't needed.
Then it will probably ask you what you want to program the bios with and you type "888ER200.BIN" and watch it reprogram. Should only take a minute. This is how a bios flash is usually done though I don't have the 8886 here any more to verify there are no changes in this case.
I'm not telling people to flash your bios and I don't know what this bios will do for you yet.
Dennis, let us know what differences you see... if you see anything about HT in any of the testing since you have the 3.06GHZ CPU installed. I VERY much doubt this bios upgrade is for that though.
