Tiger MPX (S2466) FAQ Updated 07/08/03

  1. Is there TYAN System Monitor support for this system board?

    Yes!  Please go to the following page for more details and software download.
  2. Why does my system hang during POST with my Intel Pro/1000 MT Gigabit Ethernet card installed?

    This issue was fixed in an Intel® Boot Agent Firmware update. You need to run Intel® Boot Agent v1.1.07 or newer. It can be downloaded from the following link: http://www.intel.com/design/network/drivers/sla_ibag.htm
  3. Why doesn't the BIOS (Option ROM) for PCI device show during boot up?

    The cause of the problem is that in order to be PC Compatible, the Option Rom space is limited to 128K.  This is true for any motherboard with PC compatible BIOS.

    In the common configurations, a newer AGP card (such as a Geforce 4) will require 64K of option ROM space, so you have only 64K of option ROM space left to work with. Many SCSI, NIC with PXE, IDE RAID etc. can easily use another 40-64K of option ROM space.

    By design the option ROM should shrink down to a smaller run time code after the initialization code has run. For example, some Adaptec cards will require 32K to initialize. Then they shrink down to 12K at run time; whereas some Geforce 4 cards require 64K to initialize and never release it.  Please check with the device manufacturer for the latest firmware upgrade or ask if they have a smaller option ROM available. Again, this is a limitation of the PC compatible specifications and not a failure of the motherboard BIOS.
  4. Why does my system give an NMI/Parity Error blue screen when I apply the Nvidia Detonator 23.11 drivers?

    This particular error occurs in combination with:

    1)  Nvidia's latest Detonator XP v.23.11 drivers
    2)  Geforce 3 family of video cards
    3)  AMD's AGP drivers

    If all 3 of these listed items are used in conjunction with any AMD 760 chipset motherboard you will receive this error.  Most video card manufacturers modify the drivers for their cards.  Therefore, if you use the video card manufacturer's drivers or Nvidia Detonator v.22.xx drivers (or earlier versions) you will not encounter this error message.  More information & a workaround can be found on the newsgroups
  5. Why can't I browse Network Neighborhood with my 3Com 3C996 Gigabit Ethernet Adapter?

    This is a driver issue with the 3c996 Gigabit Ethernet card and the AMD chipset.  3Com has released drivers to resolve this issue. The drivers are dated 12-18-01 & can be downloaded from ftp://ftp.3com.com/pub/nic/3c996/3c996bx5.exe or search for this driver at www.3com.com.
  6. Why did I receive a USB card with my Tiger MPX (S2466)? Doesn't the
    onboard USB work?

    Due to an issue regarding USB on the chipset, the USB will not function on the Tiger MPX (S2466). Both the stacked USB ports, and the onboard headers, will not function.

    The USB card has been provided in the box for your convenience, in case you would like to use USB devices. In addition, we have given you the I/O shield to help differentiate between onboard USB and the USB card, when plugging in USB devices. (Note: the S2466N-4M does not have this problem. For more information check AMD's website
    http://www.amd.com )
  7. What is the IRQ routing for my motherboards PCI BUS?

    PCI Bus 1 is made up of 2 64bit, 66MHz 3.3v PCI slots.
    PCI Bus 2 is made up of 4 32bit, 33MHz 3.3v/5v PCI slots.

    The Interrupt routing is:
    PCI bus 1 slot 1 = INTA ADD additional routing!
    PCI bus 1 slot 2 = INTB
    PCI bus 2 slot 1 = INTA
    PCI bus 2 slot 2 = INTB
    PCI bus 2 slot 3 = INTC
    PCI bus 2 slot 4 = INTD
    3COM LAN           INTD
  8. What kind of Power Supply can I use on the Tiger MPX?

    TYAN recommends ATX 12V power supplies. However, for your convenience, we have added an "auxiliary drive power connector" on the motherboard so that you can also use a standard ATX 2.01 or 2.03 power supply. This can be used for a system with a low to moderate power consumption. To ensure trouble free operation you need a power supply with a minimum 10A on the +12V output & 30A on +5V. Make sure that you do not plug any other drives into the auxiliary drive power connector that is plugged into the motherboard. If your system draws a lot of power, TYAN strongly suggests using an ATX 12V power supply.
  9. Why won't my CD-ROM or HDD boot?

    Check the jumper on your CD-ROM. If it is the only device on the channel it must be set to master.
  10. Why does my system display less than 4GB even though I have installed 4 GB?

    AMD chipset architecture requires memory above 3.5GB to be reserved for PCI devices. You will typically see 3.6-3.8GB available.
  11. Why does my new ATI Radeon 8500 hang during post?

    This is related to the size of the frame buffer the card requires. If you have this problem, use a different video card and flash to the latest BIOS.  Only BIOS 1.00 is affected.  http://tyan.com/support/html/b_tg_mpx.html#S2466N
  12. Why does my game port on my sound card not work?

    This is because the PCI Bridge address window cannot address the 0200-0207 Legacy ISA address range. Any card with PCI compliant drivers will be able to remap the address to a higher range through drivers.
  13. How do I boot my system without a video card?

    Boot without video card is only supported if Console Redirect is enabled in BIOS
  14. Why won't my onboard NIC work in Windows 2000?

    You MUST install the NIC drivers on the CD in Windows 2000 for the onboard NIC. The default drivers that Win2k install do not work on the onboard NIC. 
  15. Why won't my USB keyboard work to let me in the BIOS with the PCI USB controller?

    The BIOS cannot control USB ports that are not integrated into the motherboard chipset. Therefore Legacy USB is not supported.
  16. Why can't I use the esc key in my Adaptec card's BIOS?

    In BIOS 1.00 ESC key does not work while inside SCSI BIOS unless F2 key is pressed. Upgrade to the latest BIOS available here:
  17. Why does the system only show 3.5 GB of memory when I have 4.0 GB of memory installed?

    Under the current PC memory addressing, there is a memory area just below 4.0 GB which is reserved permanently.  The reserved area is for system BIOS to put APIC, ACPI Table, PCI Devices', Resources and AGP aperture information.  When your system DRAM is 3.5 GB or lower, the system will show that the same amount of memory has been implemented.  However, if the system DRAM is above 3.5 GB of memory, the actual amount of memory that the system shows will be less due to the reserved area.  Regardless of memory size, the reserved memory addressing is always present, but only when the DRAM rises above the 3.5 GB amount will that area become visible.
  18. Why does my memory test program lock up when I use 4.0 GB of memory but runs fine with anything less?

    The memory test utility accesses the reserved memory address area.  When the program accesses this area, it causes the system to be unstable and locks up.
