Minix installation demo.				Author: Kees J. Bot

	+-------------------------------------------------------+
	| This is a log of a Minix installation on my notebook  |
	| in the form of a number of screen images with bits of |
	| explanatory text in these boxes.  The floppy images   |
	| have already been made and the system is booted with  |
	| a diskette that contains both ROOT and USR combined.  |
	| That is why I typed 'fd0c' after starting Minix:      |

	| As suggested I log in as root and enter 'setup' to    |

# setup

This is the Minix installation script.

Note 1: If the screen blanks suddenly then hit F3 to select "software
        scrolling".

Note 2: If things go wrong then hit DEL and start over.

Note 3: The installation procedure is described in the manual page
        usage(8).  It will be hard without it.

Note 4: Some questions have default answers, like this: [y]
        Simply hit RETURN (or ENTER) if you want to choose that answer.

Note 5: If you see a colon (:) then you should hit RETURN to continue.

	| I hit the ENTER key and am asked about my keyboard    |

What type of keyboard do you have?  You can choose one of:

    french  italian   latin-am  scandinavn  uk      us-swap
    german  japanese  olivetti  spanish     us-std

Keyboard type? [us-std]

	+-------------------------------------------------------+
	| I'm blessed with a standard U.S. keyboard so I type   |
	| ENTER again.  Now it gets serious:                    |

Minix needs one primary partition of at least 30 Mb (it fits in 20 Mb, but
it needs 30 Mb if fully recompiled.  Add more space to taste.)

If there is no free space on your disk then you have to back up one of the
other partitions, shrink, and reinstall.  See the appropriate manuals of the
the operating systems currently installed.  Restart your Minix installation
after you have made space.

To make this partition you will be put in the editor "part".  Follow the
advice under the '!' key to make a new partition of type MINIX.  Do not
touch an existing partition unless you know precisely what you are doing!
Please note the name of the partition (hd1, hd2, ..., hd9, sd1, sd2, ...
sd9) you make.  (See the devices section in usage(8) on Minix device names.)

	| There are two partitions already present on the disk, |
	| one that contains setup stuff for the notebook and a  |
	| 208 megabyte partition that already contains Minix.   |
	| The AT disk driver has tickled the IDE disk to make   |
	| it tell its type and make.  It is a message from deep |
	| in the kernel, not from part.                         |
	| For this install I want a new partition, so I move    |
	| over to the Size field of the first unused slot, line |
	| 3 with type "None".  I could type a number now, but   |
	| I want to use the rest of the disk, so I hit 'm'      |
	| there once or twice to let part propose something.    |

Save partition table? (y/n) y

Please finish the name of the primary partition you have created:
(Just type RETURN if you want to rerun "part")                   /dev/hd3

You have created a partition named:     /dev/hd3
The following subpartitions are about to be created on /dev/hd3:

        Root subpartition:      /dev/hd3a       1440 kb
        /usr subpartition:      /dev/hd3c       rest of hd3

Hit return if everything looks fine, or hit DEL to bail out if you want to
think it over.  The next step will destroy /dev/hd3.

sure that there can not be any bad blocks.  Otherwise just wait.)
