	The V6 distribution tape contains a large number of 512-byte records; the first 101 512-byte tape blocks contain a number of small programs, including tape and disk bootstraps, and programs to copy the tape contents to disk.		The V6 distribution tape contains a large number of 512-byte records; the first 101 512-byte tape blocks contain a number of small programs, including tape and disk bootstraps, and programs to copy the tape contents to disk, and a [[directory]] which indicates what files are there.

	* Block 0 on tape - mboot (TM11 tape bootstrap)		* Block 0 on tape - 'mboot' (TM11 tape bootstrap)
	* Block 1 on tape - hboot (TM02 tape bootstrap)		* Block 1 on tape - 'hboot' (TM02 tape bootstrap)
	* Block 2-24 - a tp-format directory section for the following section		* Block 2-24 - a tp-format directory section for the following section
	* Block 25-xx - stand-alone programs, including tape->disk copy programs		* Block 25-xx - stand-alone programs, including tape->disk copy programs
	* Block 98 on tape - hpuboot (RP04 disk bootstrap)		* Block 98 on tape - 'hpuboot' (RP04 disk bootstrap)
	* Block 99 on tape - rpuboot (RP03 disk bootstrap)		* Block 99 on tape - 'rpuboot' (RP03 disk bootstrap)
	* Block 100 on tape - rkuboot (RK05 disk bootstrap)		* Block 100 on tape - 'rkuboot' (RK05 disk bootstrap)

	After that, blocks 101-4100 are an image of an RK05 pack containing a UNIX root partition, which contains everything needed to allow UNIX to run: all the commands, and the source for the operating system (to allow reconfiguration of the OS to match the system's hardware); blocks 4101-8100 are an image of an RK05 pack which contains source for all the commands; and blocks 8101-12100 are an RK05 pack image which contains all the documentation.

	The first stage tape bootstrap is "tpboot.s"; this is assembled with either "tm.s" or "ht.s" to produce the first-stage bootstrap that goes in blocks 0 and 1 of the tape. It takes as input a file-name, for installing UNIX, normally 'xxyy' as above, entered at the console. It then reads the tp-format directory off the tape, and looks for that file-name in it, and if found, loads and starts it.

It is not possible to boot V6 Unix directly from a V6 distribution tape (as one can with V7); all one can do is copy the disk images from the tape to the disk, and then boot from the disk. Also, since the file systems are provided as images of complete functional [[UNIX file system]]s, it is not possible to install them properly on different disks; to put the contents on different sized disks, one has to perform additional steps once the system is up and running.
