We’re trying to use up to three DSP cards from Advantech (http://www.advantech.com/products/DSPC-8681/mod_A9314996-0022-4927-9AA4-6B1060D4E5E8.aspx) in this system. Ideally we will be able to load all of the add-on slots but we’re nowhere near that level yet. Each card alone in any x8 or x16 slots passes POST but no seating combination of two or more cards passes.
Have any of you ever encountered a problem like this with a S2600? I have followed generic remedies to the problem on the Intel site (http://www.intel.com/support/motherboards/server/sb/CS-034070.htm). I have also seen discussions here regarding multiple NICs but not arbitrary add-ons and certainly not these DSP cards.
Steps I've taken so far:
- Updated BIOS/firmware
- Disabled unused devices and OpROMs in BIOS
- Made the following changes to the BIOS (BIOS Setup => Advanced => PCI Configuration):
- Set Maximize Memory below 4 GB to Disabled
- Set Memory Mapped I/O above 4 GB to Enabled
- Selected MMIO size of 256G
- Tried every combination of x8 and x16 seats for two cards
- Collected System Event log using Intel utility
- Added nothing to output already available in the UI
- Collected System Info using Intel utility
- Engaged Advantech with questions regarding this use of their board
- They feel it is a mother-/main-board issue and won’t investigate further
I'm relatively sure this is a BIOS/firmware issue but have tried every reasonable configuration point in the UI. It is hard to imagine that we really are exhausting PCI resources with a grand total of 8 DSP chips in the system.
Thanks for any suggestions,
Chad
