HCCS IDE interface driver
hcide* at podulebus0 slot ?
ata* at hcide? channel ?
The dtide driver handles an HCCS 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 three IDE channels. The internal 44-way IDE
    connector is channel 0, the internal 40-way connector is channel 1 and the
    external connector is channel 2.
The driver was derived by reverse-engineering the card, so it may not handle the
  card entirely optimally.
