Data Storage
Serial ATA (SATA)
The server board S875WP1-E supports Serial ATA devices using the ICH5-R controller. The ICH-5
provides the following Serial ATA support:
•
150 MB/sec transfer rate.
•
Up to two SATA devices on the server board S875WP1-E. These are indicated by the
connectors labeled SATA-B1 and SATA-B2 on the server board.
IDE Interfaces
The ICH5-R IDE controller has two independent bus-mastering IDE interfaces that can be independently
enabled. The interface handles the exchange of information between the processor and peripheral
devices like hard disks and CD-ROM drives. The IDE interfaces supports:
•
Up to four IDE devices (such as hard drives).
•
ATAPI devices (such as CD-ROM drives).
•
Laser servo (LS-120) drives.
•
PIO Mode devices.
•
Ultra DMA-33: DMA protocol on IDE bus supporting host and target throttling and transfer
rates of up to 33 MB/sec.
•
ATA-100/66: DMA protocol on IDE bus supporting host and target throttling and transfer
rates of up to 100 MB/sec. The ATA-100/66 protocol is similar to Ultra DMA and is device
driver compatible.
NOTE
ATA-100/66 is a faster timing and requires a specialized cable to reduce reflections, noise, and
inductive coupling.
The IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices using the
transfer modes.
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS)
translation modes. The drive reports the transfer rate and translation mode to the BIOS.
The S875WP1-E server board supports Laser Servo (LS-120) diskette technology through the IDE
interfaces. An LS-120 drive can be configured as a boot device by setting the BIOS Setup program's
Boot menu to one of the following:
•
ARMD-FDD (ATAPI removable media device – floppy disk drive)
•
ARMD-HDD (ATAPI removable media device – hard disk drive)
