General quality and motherboard stability are considered good, documentation just adequate. I have no information on the kind of decoupling capacitor used. A recent patch is supposed to make the Linux DMA mode 2 driver compatible with motherboards based on the SiS 5571B and other chipsets, but again I haven't been able to verify this information. The SiS 5571B and most recent non-Intel motherboard chipsets do not suffer from the 64Mb caching limitation of the VX and TX chipsets. The SiS 5598 chip has a small heatsink with a spring mounting system that maintains constant pressure on the chip, improving cooling.
Documentation is excellent, and a CD-ROM with drivers and utility programs is included.
I would say this board would be an excellent choice for a fast and stable 6x86MX-based Linux server. The PA-2007 seems particularly interesting since it is available with up to 1Mb of pipelined burst L2 cache, and has switching voltage regulator circuitry. Top host bus speed is 75 MHz. We can say it combines the best features from the HX and TX chipsets, and even adds a few of its own. The first report I received on this board came from Mike Brownlow, who is using it with a 6x86MX-PR200 processor.
