  • Page 45: Programming Flash Rom

    Programming Flash ROM All versions of the Megathon PCI motherboard use Flash EPROM to store the system BIOS. The advantage of Flash EPROM is the EPROM chip does not have to be replaced to update the BIOS. The end user can actually reprogram the BIOS, using a ROM file supplied by American Megatrends.

  • Page 46: S804P.rom

    S804P.ROM S804P.ROM resides on a floppy disk and contains the updated main BIOS code. American Megatrends will provide this file when the AMIBIOS for the Megathon PCI ISA motherboard must be updated. S804P.ROM must be present in the root directory of the floppy disk before the onboard Flash EPROM can be reprogrammed.
  • Page 47 Programming the Flash ROM, Beep Codes The bootblock code produces a series of beeps during Flash ROM programming to: signify completion of a step (as shown on the previous page), or to signal an error. Error beeps are arranged in a coded sequence and have different meanings depending on when they occur.

  • Page 49: Deleting A Password

    Deleting a Password If you forget the passwords you set up through AMIBIOS Setup, the only way you can restart the computer is to erase the system configuration information where the passwords are stored. System configuration data is stored in CMOS RAM, a type of memory that consumes very little power.

  • Page 50: Avoid Static Electricity
