PPC - Peripherals - SiI for ATA-133

This seems to be one of the most popular AmigaOne add-ons, because it not only gives faster disk access using the standard Parallel ATA (PATA) IDE drives and ATAPI devices but also overcomes the DMA data-loss issues that have been encountered using the AmigaOne's onboard VIA IDE controller. IDE drives can operate in two modes:
  • PIO (Programmed Input/Output)
    a method of moving data by sending control data through the CPU. There are different modes of PIO which specify the transfer rate, with mode 0 at 3.3 MBps up to mode 4 at 16.6 MBps.
  • UDMA (Ultra Direct Memory Access)
    a protocol for transferring data directly between a hard drive through the bus to and from a computer's main memory without involving the CPU. There are different modes of UDMA which specify the transfer rate, with mode 0 at 16 MBps up to mode 6 at 133 MBps.
Most PATA IDE drives sold today are Ultra ATA and can operate in either PIO and UDMA, but may not support all modes. For example, the Seagate Barracuda 7200.7 drives which many of our members use, support PIO modes 0-4 and UDMA modes 0-5, giving a maximum speed of 100 MBps. To find out what speed your drive can run, you can check the manufacturers specifications or use idetool on the AmigaOne.

To the best of our knowledge, any PCI IDE board using the Silicon Image SiI0680 chipset is suitable, and there are several readily available. Two cards used by menbers of Amiga Auckland are the ST Lab Ultra ATA IDE Controller Card, and the XSonic Ultra ATA IDE Controller Card.

ST Lab Ultra ATA IDE Controller Card

This card uses the Silicon ImageSiI0680ACL144 chip, SiI680-IDE for short, and costs around NZ$66 incl GST. It comes with two 440mm 80 wire ribbon cables, a CD containing Drivers and Utility programs and a multi-page User Manual exclusively for the Microsoft environment. It has two 40 pin ATA-133 sockets (the Primary channel is labelled J3 and coloured red, and the Secondary channel is labelled J5 and coloured blue).

Specifications
The specifications for the card are:

  • Chipset: Silicon Image SiI0680
  • Compliant with ATA/ATAPI-6 specifications
  • Compliant with PCI Plug & Play
  • Data Transfer Rate: max. IDE/ATA data transfer rate of 133MB/sec
  • Bus: PCI 2.2 32-bit, 33MHz
  • Features Virtual DMA: Bus master transfer on the PCI Bus and PIO transfer on the ATA bus
  • Two independent Ultra ATA channels with 256 Bytes FIFO per channel
  • Supports up to four IDE/ATA devices (coexists with other IDE and SCSI controllers)
  • Fully backwards compatible with Ultra ATA/100, Ultra ATA/66, EIDE/Fast ATA-2, IDE and ATAPI devices
  • Supports Ultra and Multi-Word DMA timing modes
  • Enhanced data integrity of transferred data with CRC (Cyclical Redundancy Check)protection and verification
