driver for scsi card

[Robert Storey]

I have an Acard SCSI card, and the only device attached to it is an external 
CD-R drive.

I need to load a driver to make it work. Dmesg seems to make this clear:

    bob at pro:~> dmesg | grep -i scsi
    pci0: <mass storage, SCSI> at device 13.0 (no driver attached)

With Linux, to use this drive, I have to load a module, as such:
    modprobe atp870u

I believe that the FBSD equivalent to "modprobe" is "kldload", but 
unforunately I can find no module name "atp870u" and I don't know what the 
equivalent is. Perhaps there is no module in FBSD that will work? I don't 
know how to figure out which FBSD module, if any, will do the job. If there 
is no FBSD module, is there any way to get the Linux modules to work in FBSD?

TIA,

Robert
