ALi PCI Chipset Integrated PATA Ports

Contents

Hardware Support

This driver provides the support for the ALi/ULi PCI and PCI-X chipset integrated PATA ports.

Modes Supported

PIO, MWDMA, UDMA

Limitations

Early chipsets do not support LBA48 access for DMA. On PATA functions prior to revision 0xc5 the driver will use PIO when accessing those part of a large disk above the 137GB line.

Known Problems

Some systems have problems with ATAPI DMA. The cause is unknown, by default ATAPI DMA is therefore disabled.

Module Options

atapi_dma = 0/1
