Parallel BZIP2 1.0.4 (Default branch)
ImagePBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (ie: anything compressed with PBZIP2 can be decompressed with bzip2).License: BSD License (original)Changes:
Support was added for using pbzip2 with tar andfor all remaining bzip2 command line options, sopbzip2 can be used as a drop-in replacement forbzip2. A bug was fixed that would cause pbzip2 tocrash if detection of the number of processorsfailed. Compiling with uclibc is now supported.Image

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.

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.
