You add a hard drive, and configure the file systems on it, by running "mkdev hd". If you are curious as to what goes on behind the scenes, look in /usr/lib/mkdev. The "hd" command there is a shell script, and is fairly self-explanatory. You generally have to run 'mkdev hd' twice. If I remember correctly, the new kernel already has the code for the second IDE drives, so in that case it's only once. But for SCSI drives, the first invocation puts the driver code in, and the second (after a reboot) allows the partitioning and division of the drive.

For SCSI drives, the first pass asks you the name of the SCSI controller. If you don't know, and if your primary drive already is SCSI, look in /etc/conf/cf.d/mscsi.

vpo

VPO(4)							   BSD Kernel Interfaces Manual 						    VPO(4)

NAME

     vpo -- parallel to SCSI interface driver

SYNOPSIS

     device vpo

     For one or more SCSI busses:
     device scbus

DESCRIPTION

     The vpo driver provide access to parallel port Iomega Zip and Jaz drives.

HARDWARE

     The vpo driver supports the following parallel to SCSI interfaces:

     o	 Adaptec AIC-7110 Parallel to SCSI interface (built-in to Iomega ZIP drives)
     o	 Iomega Jaz Traveller interface
     o	 Iomega MatchMaker SCSI interface (built-in to Iomega ZIP+ drives)

USAGE

     The driver should let you use a printer connected to the drive while transferring data.

     DOS and FreeBSD file systems are supported.  When mounting a DOS file system or formatting a FreeBSD file system, check the slice of the disk
     with the fdisk(8) utility.

     In order to unixify a ZIP disk, put the following in /etc/disktab:

     zip|zip 100:
	     :ty=removable:se#512:nc#96:nt#64:ns#32:
	     :pa#196608:oa#0:ba#4096:fa#512:
	     :pb#196608:ob#0:bb#4096:fb#512:
	     :pc#196608:oc#0:bc#4096:fc#512:

     and use bsdlabel(8).

     If you have trouble with your driver, your parallel chipset may not run properly at the detected mode (NIBBLE, PS2 or EPP).  Tune the ppc(4)
     bootflags to force other modes.

SEE ALSO

     da(4), lpt(4), ppbus(4), ppc(4), scsi(4)

HISTORY

     The vpo manual page first appeared in FreeBSD 3.0.

AUTHORS

     This manual page was written by Nicolas Souchu.

BUGS

     During boot, the driver first tries to detect a classic ZIP, then a ZIP+.	The ZIP+ detection is intrusive and may send erroneous characters
     to your printer if the drive is not connected to your parallel port.
