NAME
aceride —
PCI IDE disk controllers
driver
SYNOPSIS
aceride* at pci? dev ? function ? flags
0x0000
DESCRIPTION
Theaceride driver supports the Acer Labs M5229 IDE
controllers, and provides the interface with the hardware for the
ata(4)
driver.
The 0x0002 flag forces the aceride 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.
