I would say the controllers you are talking about might be on a disk storage which has normally 2 controllers on it.

Cheers,

NAME
hptide -- Triones/Highpoint IDE disk controllers driver SYNOPSIS
hptide* at pci? dev ? function ? flags 0x0000 DESCRIPTION
The hptide driver supports the Triones/Highpoint HPT366, HPT370, HPT370A, HPT372 and HPT374 IDE controllers, and provides the interface with the hardware for the ata(4) driver. The 0x0002 flag forces the hptide 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. SEE ALSO
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4) BUGS
The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 30 or 33 MHz. This driver may not work properly on overclocked systems. BSD
