dtide —
D.T. Software IDE interface driver
dtide* at podulebus0 slot ?
atabus* at dtide? channel ?
The dtide driver handles a D.T. Software IDE interface
  plugged into an Acorn expansion slot. It uses the standard
  NetBSD IDE controller driver, and hence can use the
  standard atabus driver.
The card provides two IDE channels. The external IDE connector is
    channel 0, while the internal connector is channel 1.
The driver was derived by reverse-engineering the card and its RISC OS driver,
  so it may not handle the card entirely optimally.
