ACERIDE(4) Device Drivers Manual ACERIDE(4) NAME aceride - PCI IDE disk controllers driver SYNOPSIS aceride* at pci? dev ? function ? flags 0x0000 DESCRIPTION The aceride 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. 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. NetBSD 8.99.34 October 8, 2003 NetBSD 8.99.34
