The iha driver supports PCI SCSI host adapters based on
  the Initio INIC-940 and INIC-950 chips.
The INI-9090U, INI-9100U/UW, the Iwill 2935UW and the IOI
    Technology IOI-4203U have been tested.
The iha driver was originally written for
  OpenBSD by Kenneth R. Westerback, based on a
  FreeBSD driver by Winston Hung. Izumi Tsutsui ported
  the driver to NetBSD.
iha driver does not currently use tagged command
  queuing.
