Does the D815EEA desktop board support Ultra ATA/66, as well as, ATA/100 hard drives? ?
Yes. One of the new features of the Intel Desktop Board D815EEA is its ability to support all Ultra ATA transfer rates (i.e., 33 MB/sec, 66 MB/sec and 100 MB/sec). To realize a true throughput performance difference, a hard drive may need to implement higher spindle speeds, such as 7200 RPM, and a large onboard buffer size to take advantage of the increased bandwidth available on the IDE channel. • Does the IDE cable provided with the D815EEA desktop board support both Ultra ATA/66/100 and previous IDE transfer protocols? The 40-pin, 80-conductor cable that is provided with the D815EEA desktop board is fully backward compatible with all IDE transfer protocols. It will also support Ultra ATA/100 if one or two Ultra ATA/100 drives are attached. If two drives with different Ultra DMA protocols are used on the same cable, the slower Ultra DMA protocol is used for both drives. It is recommended that the Ultra ATA/100 drives be attached to the primary IDE channel using the provided cable and
