SYNOPSIS
acardide* at pci? dev ? function ? flags
0x0000
DESCRIPTION
Theacardide driver supports the following IDE
controllers:
- Acard ATP850U Ultra33
- Acard ATP860 Ultra66
- Acard ATP860-A Ultra66
- Acard ATP865-A Ultra100
It provides the interface with the hardware for the ata(4) driver.
The 0x0002 flag forces the acardide driver
to disable DMA on chipsets for which DMA would normally be enabled. This can
be used as a debugging aid, or to work around problems where the IDE
controller is wired up to the system incorrectly.
