I currently own a rosewill rc-208 ide hdd controller and in order to be prepare with vista, I try to upgrade to the latest bios since i read the site I need 3.2.24 in order for the vista driver to work, and I currenbtl use 3.2.10, and when I try to update the bios, it keep asking me what kind of flash memory do my controller has. How DO I determine that exactly?
