NAME
     wdc - WD100x compatible hard disk controller driver

SYNOPSIS
     # alpha/i386

     wdc1 at isa? port 0x170 irq 15 flags 0x00

     # macppc
     wdc* at macobio?
     wdc* at kauaiata?

     # landisk
     wdc0 at obio? port 0x14000000 irq 10

     # all architectures
     wdc* at pcmcia?

     atapiscsi* at wdc?* flags 0x0000
     wd* at wdc? flags 0x0000

DESCRIPTION
     The wdc driver provides the basic functions for the wd(4) and
     atapiscsi(4) drivers.  It supports IDE and EIDE controllers, as well as
     MFM, RLL, and ESDI on the ISA bus.	 PCI IDE controllers in legacy mode
     are also supported, but the pciide(4) driver may provide more
     functionality.

     For the isa(4) front-end, setting flags to 0x01 enables 32-bit I/O
     negotiation.  This is known to cause problems with some motherboards.

     pciide(4), pcmcia(4), scsi(4), wd(4)
