Does the Desktop Board D845GERG2 support Ultra ATA/100 hard drives?

Yes. The Desktop Board D845GERG2 supports Ultra ATA transfer rates up to 100 MB/sec (ATA/100) by way of the ICH4 IDE controller with two independent bus-mastering IDE interfaces. An Ultra ATA/100 supported hard drive and an 80 conductor IDE cable are required to take advantage of the increased bandwidth available on the IDE channel. One of the new features of the Intel Desktop Board D845GERG2 is its ability to support larger ATA/100 capable hard drives with 48-bit Logical Block Addressing (LBA) within the BIOS along with 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.
