This file explains the procedure for changing the configuration of
SNOBASIC. It is assumed that you have read the "Getting Started"
section of the manual and the "Configuring" section of the manual
before proceeding in this file.

This file has sections dealing with the major topics of re-configuration.
You should proceed now to the section that deals with the configuration
you wish to perform.

HARD DISK SYSTEMS

    Insure that you are in the root directory of your hard disk ("cd \").

    Create a directory on your hard disk named SNOW ("md snow").

    Copy the root directory of SNOBASIC disk one to the directory SNOW
    ("copy a:\*.* c:\snow").

    Create a directory on your hard disk named DK0 ("md dk0").

    Copy the DK0 directory from SNOBASIC disk one to the directory DK0
    on your hard disk ("copy a:\dk0\*.* c:\dk0").

    Place SNOBASIC disk two in a.

    Create a directory on your hard disk named DK1 ("md dk1").

    Copy the DK1 directory from SNOBASIC disk two to the directory DK1
    on your hard disk ("copy a:\dk1\*.* c:\dk1").

    Use a text editor such as EDLIN to make the following change to
    the STARTUP.BAT file that you wish to use:
        SET D1=B:\DK1    should now be    SET D1=\DK1

    Change directories to the directory SNOW ("cd snow").

    Bring up SNOBASIC ("startup" or "startup2" or "startup3").

ONE DRIVE SYSTEMS:

    First, be sure that you have made a copy of SNOBASIC disk one
    as described in the "INSTALL.DOC" file. This will place DOS
    on SNOBASIC disk one.

    Format a blank disk ("format b:")

    Create a directory DK0 on the new disk ("md b:dk0").

    Copy the DK0 directory of SNOBASIC disk one to the new disk
    (Place SNOBASIC disk one in the drive and "Copy a:\dk0\*.* b:\dk0".
    DOS will prompt you to swap disks from time to time.)

    Make a directory DK1 on the new disk ("md b:dk1").

    Copy the programs and files that you wish to use from SNOBASIC disk
    two to the DK1 directory on the new disk (SNOBASIC disk two will
    be disk a and the new disk will be disk b. Type
    "Copy a:\dk1\filename b:\dk1\" for each file to be transferred.
    DOS will prompt you to swap disks from time to time.)

    Use a text editor such as EDLIN to make the following change to
    the STARTUP.BAT file (on SNOBASIC disk one) that you wish to use:
        SET D1=B:\DK1    should now be    SET D1=\DK1

    With SNOBASIC disk one in the drive, bring up SNOBASIC ("startup"
    or "startup2" or "startup3").

    When asked for a license number, before answering the question,
    remove SNOBASIC disk one and place the new disk into the drive.
    Then answer the license number question.

INTERFACE BOARDS (TERMINALS) OTHER THAN COM1 OR COM2:

    First, read the section "Configuring" in the manual.

    It is necessary to know the "device address" of your board. This
    should be listed somewhere in the documentation that came with
    your board. The device address given there will probably be
    given in "Hexadecimal" notation. It must be converted to decimal
    to be used here. (Your dealer may be able to help you or you
    may call Snowcrest at 916-926-3817 for help).

    Add a "set" command to the "STARTUP.BAT" file that you wish to
    use. Usually this will be:
        SET U3=aaaa,ii,ssss
    Where aaaa is the device address as discussed above. ii is the
    interrupt level of the new board. Unless your board is capable
    of using interrupt level 2 (should be stated in the documentation
    if so - most boards use only level 3 or level 4), you will be
    assigning this new board to "piggyback" on the clock interrupt
    by setting ii to 128. ssss is the baud rate that you wish for the
    new board. This may be selected from the list given in the manual
    or may be the number zero (0). If you choose zero, the baud rate
    will be changed every time the user presses "break" on his terminal
    (cycling through 110, 300, 1200 and 9600 baud). You may also find
    that the rate will change when the terminal is turned off, so this
    option should primarily be used only on telephone lines with modems.

    Don't forget to change the entry in the STARTUP.BAT file "NU" to
    reflect the new number of users ("SET NU=4").

LARGE SYSTEMS - "OUT OF ENVIRONMENT SPACE"

    As you add information to the DOS environment by adding SET commands
    or by adding to the length of the existing SET commands, you may
    encounter the problem of running out of environment space. DOS provides
    a mechanism for increasing the space needed to hold SET commands, but
    this mechanism only works when you type the SET commands from the
    keyboard. The SET commands for SNOBASIC come from the STARTUP.BAT
    files, and DOS will not allocate more space when these files are
    being used. SNOBASIC is distributed with a program called ENVIR which
    will modify COMMAND.COM on the disk you wish to use for SNOBASIC to
    allocate additional environment space when the system is booted
    (power on or ctrl-alt-del). If you encounter the problem of running
    out of environment space, you need to perform the following steps:

    First, insure that you have made a copy of SNOBASIC disk one as
    described in the INSTALL.DOC file.

    Place the copy of SNOBASIC disk one in drive a if you are running
    on a floppy disk system.

    Boot the system (ctrl-alt-del).

    If you have a hard disk system, type "path \snow".

    Type "envir 30". The number 30 tells the system to provide thirty 16
    byte blocks to hold the environment SET commands (total 480 bytes).
    This number may be as large as 99 or as small as 6, but the recommended
    number for SNOBASIC is 30. (Typing "envir 14" will restore DOS to its
    original state).

    When the DOS prompt returns, boot the system again (ctrl-alt-del). There
    is now enough space in the environment to hold the necessary SET commands.

    This procedure modifies the program COMMAND.COM on the root directory
    of the disk. In order to have the additional space in the environment,
    you must boot from the disk that has been modified. If you boot from
    another disk first, such as your original DOS disk, and then change
    to the SNOBASIC disk to run SNOBASIC, you will again run out of
    environment space.

PRINTERS:

    SNOBASIC accesses the printer through the DOS device PRN:. This device
    may be changed by use of the DOS "mode" command to be LPT1, LPT2,
    COM1 or COM2. If it is desired to use a serial printer, you must
    insure that the same serial port is not assigned by SNOBASIC to a
    user. If you have both COM1 and COM2 and need a serial printer, the
    easiest way to configure for it is to place the printer on COM2,
    use the DOS "mode" command to inform DOS that the printer is on
    COM2, and bring SNOBASIC up using STARTUP2.BAT, thus configuring
    only COM1 for SNOBASIC. If you have only COM1, you may bring SNOBASIC
    up using STARTUP.BAT (thus having only a single user basic) and
    place your printer on COM1. If you wish to use COM1 in this case
    for a terminal, you should first set PRN: to LPT1 or LPT2 with
    the DOS "mode" command and use STARTUP1.BAT to start SNOBASIC.
    The serial printer then would not be used by SNOBASIC.

    Of course, if you have a parallel printer, there is no such problem.
