# NAME

slide — Symphony Labs and Winbond IDE disk controllers driver

# SYNOPSIS

slide* at pci? dev ? function ? flags 0x0000

# DESCRIPTION

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.

# SEE ALSO

ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)

# BUGS

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.
