It was me that Jordan was refering to regarding getting a P6 system. The 150Mhz part is escentially the only one that is available from Intel at this time. Only a very small number of 200Mhz parts have shipped, and they went to just a couple of large (PC) distributors. It is likely that 200Mhz parts will continue to be scarce until at least February '96. The biggest problem with the ASUS P6 motherboard is the poor PCI performance. DMA writes to memory are very slow because the PCI write buffer is disabled. It's disabled to work around a bug in the Intel Orion chipset that causes the data to get corrupted if it is enabled. With it disabled, the top performance of PCI DMA writes to memory is about 4.4MB/sec. This is too slow for fast (100Mbit) ethernet, for example, and causes half of the packets to get dropped. -DG
