Hardware compatibility What kind of hard drives does FreeBSD support?
FreeBSD supports EIDE and SCSI drives (with a compatible
controller; see the next section), and all drives using the
original "Western Digital" interface (MFM, RLL, ESDI, and
of course IDE). A few ESDI controllers that use proprietary
interfaces may not work: stick to WD1002/3/6/7 interfaces
and clones.
Which SCSI controllers are supported?
FreeBSD supports the following SCSI controllers:
AH-152x Series <ISA>
AH-154x Series <ISA>
AH-174x Series <EISA>
Sound Blaster SCSI (AH-152x compat) <ISA>
AH-2742/2842 Series <ISA/EISA>
AH-2820/2822/2825 Series (Narrow/Twin/Wide) <VLB>
AH-294x and aic7870 MB controllers (Narrow/Twin/Wide) <PCI>
AH-394x (Narrow/Twin/Wide)
)
BT-545 Series <ISA>
BT-742 Series <EISA>
BT-747 Series <EISA>
BT-946 Series <PCI>
BT-956 Series <PCI>
NCR 53C82x based controllers <PCI>
NCR 53C860/75 based controllers <PCI>
Trantor 130 based controllers <ISA>
UH-24f Series <EISA>
UH-34f Series <VLB>Which CD-ROM drives are supported by FreeBSD?
Any SCSI drive connected to a supported controller is supported.
The following proprietry CD-ROM interfaces are also supported:
Mitsumi LU002 (8bit), LU005 (16bit) and FX001D (16bit 2x Speed).
Sony CDU 31/33ASound Blaster Non-SCSI CD-ROMMatsushita/Panasonic CD-ROMATAPI compatible IDE CD-ROMs
All non-SCSI cards are known to be extremely slow compared to
SCSI drives, and some ATAPI CDROMs may not work.
As of 2.2 the FreeBSD CDROM from Walnut Creek supports booting
directly from the CD.
Does FreeBSD support ZIP drives?
FreeBSD supports the SCSI ZIP drive out of the box, of course. The
ZIP drive can only be set to run at SCSI target IDs 5 or 6, but if
your SCSI host adapter's BIOS supports it you can even boot from
it. I don't know which host adapters let you boot from targets
other than 0 or 1... look at your docs (and let me know if it works
out for you).
There is no built in support for the parallel ZIP drive, and if you
haven't bought your ZIP drive already I recommend you get the SCSI
one... the price is the same, and the performance is much better,
and you're unlikely to ever be able to boot from the parallel port.
If you already have a parallel ZIP, there is a port of the Linux
driver available at
in France.

Does FreeBSD support JAZ, EZ and other removable drives?
Apart from the IDE version of the EZ drive, these are all SCSI
devices, so the should all look like SCSI disks to FreeBSD, and
the IDE EZ should look like an IDE drive.
