and are trying to flash their bios to 2.50 from Optorite. I suggest downloading it from the Global Portion of their website. I downloaded from the U.S.A. and the file was 250.zip. I tried to flash the bios with that file. I couldn't get it to flash came up with something about not being the correct drive. So I went to the Global and downloaded the update which I notice was a different file 250.zip. I was able to flash the bios with the one from the Global website.
My theory on this, even though the U.S.A. says the latest FW is 2.50 but the file is really 1.50.
