Symphony Labs and Winbond IDE disk controllers driver
slide* at pci? dev ? function ? flags 0x0000
The slide
driver supports the Symphony Labs 82C105 and
Winbond W83C553F IDE controllers, and provides the interface with the hardware
for the ata(4) driver.
The 0x0002 flag forces the slide
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.
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.
