The settings are Absent, Slot D, Slot E, or Slot F. PCI IDE IRQ Connected to This option specifies the way in which the PCI IDE IRQ in any of the PCI slots is connected.
  • Page 93 Peripheral Setup, Continued PCI IDE Prefetch Mode Enabling this option enables this performance enhancement feature on the onboard PCI IDE. IDE data prefetch, when enabled, saves valuable CPU time by taking the data from the IDE drive ahead of the CPU request.

  • Page 97: Setting A Password

    Section 3 WinBIOS Password Support WinBIOS Setup has an optional password feature. The system can be configured so that all users must enter a password every time the system boots or when WinBIOS Setup is executed. Setting a Password The password check option is enabled in Advanced Setup (see page 21) by choosing either Always (the password prompt appears every time the system is powered on) or Setup (the password prompt appears only when WinBIOS is run).

  • Page 98: Changing A Password

    Changing a Password Select the Password icon from the Security section of the WinBIOS Setup main menu. Enter the password and press <Enter>. The screen does not display the characters entered. After the new password is entered, retype the new password as prompted and press <Enter>. If the password confirmation is incorrect, an error message appears.
  • Page 99 Section 4 Default The icons in this section permit you to select a group of settings for all WinBIOS Setup options. Not only can you use these icons to quickly set system configuration parameters, you can choose a group of settings that have a better chance of working when the system is having configuration-related problems.

  • Page 101: Flash Rom Programming

    The advantage of using a Flash EPROM is that 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. There are three methods for programming the Flash EPROM: program from system boot, •...
  • Page 102 The AMIFlash portion of Flash EPROM is not programmed. S717P.ROM S717P.ROM resides on a floppy disk and contains the updated main BIOS code. American Megatrends will provide this file when the WinBIOS for the Atlas PCI Pentium motherboard must be updated.
  • Page 103 Reprogramming from System Boot, Sequence of Operation The following table lists the sequence of operation and the expected behavior of the AMIFlash Code. Step Action 1 Look for floppy disk. Look for S717P.ROM on the floppy disk. Read the floppy disk. Check the BIOS file size.
  • Page 104 Reprogramming from System Boot, Beep Codes During normal operation, the Flash utility produces a series of beeps 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. The following list describes the error beep codes and when they can occur.
  • Page 105 AMIFlash Checkpoint Codes Code Verify the AMIFlash BIOS checksum and disable internal cache memory. Make the CMOS RAM checksum bad and initialize the CMOS RAM status registers. Disable DMA Controllers 1 and 2 and Interrupt Controllers 1 and 2. Initialize the chipset registers. If the main BIOS is good, transfer control to the main BIOS.
  • Page 106 AMIFlash Starting AMIFlash Type AMIFlash and press <Enter> at the DOS prompt. AMIFlash will prompt for the filename. Type S717P.ROM and press <Enter>. Pressing <Esc> exits AMIFlash any time before Flash EPROM reprogramming begins. General Operation If Flash EPROM is present, AMIFlash asks if you want to save the existing BIOS file. If you choose to save the BIOS, enter the filename where the existing BIOS will be saved.
  • Page 107 AMIFlash, Continued Enter the filename with which Flash EPROM will be reprogrammed (S717P.ROM). AMIFlash reads the file and displays a startup message. A Press any key to continue. After Flash programming starts, programming activity is indicated by a rotating / character. AMIFlash informs you when Flash programming is successful (as shown below).

  • Page 109: A Temperature And Power

    You must make sure that there is adequate air flow over the CPU inside the case. Humidity The recommended humidity range for operation of the American Megatrends Atlas EISA Pentium motherboard is 20% to 80% non-condensing. Atlas PCI Pentium EISA Motherboard User's Guide...
  • Page 110 Temperature and Power, Continued Power Requirements The Atlas EISA Pentium motherboard requires +5V ~9A. The ISA bus requirements are: +3.3V ~13A ~24A 1.6A +12V -12V 2.4A The +12V power supply to the EISA bus is limited by the power connector. The +5V supply current to the EISA bus is limited by the power connectors.
