Functional Architecture
3.2.8
IDE Interface
The 6300ESB I/O IDE controller has two independent bus-mastering IDE interfaces that can be
independently enabled. The IDE interfaces support the following modes:
• Programmed I/O (PIO): processor controls data transfer.
• 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to
16 MB/sec.
• Ultra DMA: DMA protocol on IDE bus supports Ultra 100 DMA Mode Transfers up to
100Mbytes/s for reads from disk;88.88 Mbytes/s for writes to disk. As well as Ultra66
and Ultra33 DMA mode..
• ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer
rates of up to 66 MB/sec. The ATA-66 protocol is similar to Ultra DMA and is device
driver compatible.
• ATA-100: DMA protocol on IDE bus allows host and target throttling. The 6300ESB I/O
ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates
up to 88 MB/sec.
✏ ^NOTE
ATA-66 and ATA-100 are faster timings and require a specialized 40-pin, 80-wire 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 server board SE7210TP1-E supports Laser Servo (LS-120) diskette technology through the
IDE interfaces. The BIOS supports booting from an LS-120 drive.
✏ NOTE
The BIOS will always recognize an LS-120 drive as an ATAPI floppy drive. To ensure correct
operation, do not configure the drive as a hard disk drive.
3.2.9
Serial ATA (SATA) Controller
The SATA controller supports two SATA devices providing an interface for SATA hard disks and
ATAPI devices. The SATA interface supports PIO IDE transfers up to 16 Mb/s and Serial ATA
transfers up to 1.5 Gb/s (150 MB/s). The 6300ESB I/O’s SATA system contains two
independent SATA signal ports. They can be electrically isolated independently. Each SATA
device can have independent timings. They can be configured to the standard primary and
secondary channels.
