Thunder K8S (S2880) FAQ Updated 10/27/03
 

  1. Why doesn't the BIOS (Option ROM) for PCI devices show during boot up?

    The root cause 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.  Every device that uses an Option ROM or "initialization code" to run during boot will occupy some of this 128k of memory.  Some cards can use up to 64k, leaving only 64k remaining for other devices.  SCSI, PXE, RAID and etc. can easily use another 40k to 64k of Option ROM space.  By design the Option ROM should compact itself to a smaller "run time code" after the "initialization code" has run.  For example, some Adaptec cards require 32k to initialize.  Then they shrink down to 12k at run time; whereas some AGP cards require 64k to initialize but they never compact at run time.  It can sometimes help to change the PCI Scan order in the BIOS.  Also, check with the device manufacturer for the latest firmware upgrade or ask if they have a smaller Option ROM available.
     
  2. Is there TYAN System Monitor support for this system board?

    Yes!  Please go to the following page for more details and software download.

  3. Is there any power supply, chassis, or cooling recommendations?

    Yes!  Please check here for details and listings.
     
  4. What does it mean when my board beeps at me 15 times?

    A 15 beep code means that the board is not recognizing the memory that is on the board either due to compatibility issues with the specific memory or the memory slots themselves are damaged or not seated properly.
     
  5. Where are the drivers for the RAID options of the PDC20378 Promise chipset?

    You will first need to upgrade to the beta BIOS version 2.01q available for download here: http://www.tyan.com/support/html/bios_support.html#beta
    You can then enable RAID support for the chip. The drivers are available for download at our ftp site:
    ftp://ftp.tyan.com/promise/PDC20378_RAID/
     
  6. Are there any kind of configuration issues I should keep in mind when populating the memory slots with this product?

    Always install the memory beginning with CPU1_DIMM1.  In order to access memory on CPU2_DIMM1 or DIMM2, both processors must be installed.  Memory in CPU2_DIMM1 or DIMM2 is not required when running dual CPU configurations.  AMD Opteron processors support 64bit (non-interleaved) or 128bit (interleaved) memory configurations. At least one Registered DDR SDRAM module must be installed for the system to turn on and POST (Power On Self Test). 128MB, 256MB, 512MB, 1GB, and 2GB (not tested at this time) Registered PC2700/PC2100/PC1600 DDR SDRAM memory modules are supported. All installed memory will be automatically detected upon POST. The Thunder K8S will support up to 12GB of memory (only 6GB validated at this point).
     
  7. What is the proper orientation for my memory if I want 64 bit support or if I want 128 bit transfer support?
