slide —
Symphony Labs and Winbond IDE disk
controllers driver
SYNOPSIS
slide* at pci? dev ? function ? flags
0x0000
DESCRIPTION
Theslide 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.

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.
