The new revision of the Articia S which is shipping with the new A1-XE boards seems to operate flawlessly.
Both Mai and Hyperion conducting very extensive testing on it, especially with respect to DMA transfers and other issues supposedly experienced on the Pegasos.
We used several PCI based IDE and SCSI controllers and carried out very heavy, overnight tests.
We did run into some well-documented issues with respect to the VIA 686B Southbridge but these issues were addressed in the firmware, just as they were on the PC for millions of PC mainboards.
Overall, we are more than satisfied with the quality and reliability of the hardware.
