If the shadow areas are not write protected, any virus could infect them. The images on disc would be subject to corruption, although possibly not infection (being a BIOS image, it'd probably not have a .COM or .EXE extention, so a virus probably wouldn't recognize it as infectable). EEPROM might be a little safer, but not much. - -- Gary Heston { uunet!sci34hub!gary } System Mismanager SCI Technology, Inc.
