# NAME

`rdcide` —
RDC IDE disk controllers driver

# SYNOPSIS

`rdcide* at pci? dev ? function ? flags 0x0000`

# DESCRIPTION

The `rdcide` driver supports the RDC IDE controller as found in the vortex86 and PMX-1000 system on chip, and provides the interface with the hardware for the ata(4) driver.

The 0x0002 flag forces the `rdcide` 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.
