Try pulling a stick of RAM out to get you under 4GB. There can be a lot of goofy issues that arise with 4GB memory and 32 bit operating systems--especially with a few expansion cards installed.
The package is named 188.8.131.520 because one or more of the inf's contained in it are of that revision, not all of them are.
I am still working on testing with 2 GB of memory. I assume the system will work with only one DIMM installed? I am just waiting on tech support to make this change.
I tested the system with a PCIe x1 SATA RAID controller card instead of the Sea Level cards. The SATA card did not interfere with my PCI card. The SATA card is using the same IRQ as the Sea Level cards and a larger I/O and memory address region. So I cannot understand why the Sea Level card prevents my IOTech PCI card from working while the SATA card causes no interference.
I had Device Manager organize the hardware by resource type, and I noted that there are 11 entries for sharing IRQ 16. The PCI/PCI bridge in the chipset PCH, the Nvidia video card, and the Sea Level cards are all using that IRQ. Is there some kind of limit on IRQ sharing? The IOTech PCI card does not use an IRQ but of course it does depend on the PCI/PCI bridge.
