Limitations
ALi M1523 and ALi M1523B are supported neither by the PATA driver nor by the latest IDE driver
DMA engine supports 28 bit LBA only on revisions C4 and earlier, so PIO modes are used for transfers above 137GB
Known Problems
UDMA is turned off on WD disks because UDMA CRC check fails
ATAPI DMA is disabled (use IDE driver instead if you need DMA)
Cannot have two ATAPI devices on the same channel
Older southbridges are limited to 255 sector transfers
Module Options
atapi_dma= - 0 ATAPI DMA is disabled, 1 ATAPI DMA is enabled
