ACARDIDE(4) | NetBSD Kernel Interfaces Manual | ACARDIDE(4) |
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.
