cypide -- Cypress IDE disk controllers driver
cypide* at pci? dev ? function ? flags 0x0000
The cypide driver supports the Cypress 82C693 IDE controllers, and pro-
vides the interface with the hardware for the ata(4) driver.
The 0x0002 flag forces the cypide 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.
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)
The timings used for the PIO and DMA modes for controllers listed above
are for a PCI bus running at 30 or 33 MHz. This driver may not work
properly on overclocked systems.
