<font color=red>Bug in Intels Chipsets??
[ By VooDoo >> Jan 15th, 2002 @ 9:35 pm ]
After reading an article a few weeks ago that claimed VIA had a bug in its IDE controllers which caused slow Burst speeds it was interesting to read this....

Question: My ATA100+ drive on Intel Chipset gets only ~80MB/s burst rate and not higher!

Answer: As per errata documents from Intel's website developer.intel.com, the 850, 860 chipsets have a PCI issue (Err 5. Sustained PCI Bandwidth) that limits the PCI transfer rates to 90MB/s rather than 133MB/s. Thus the ICH or external PCI disk controller will be constrained to rates ~80MB/s.
