关于参数的说明！
Usage
=========
Run SHCDX33C with the name of one or more CD-ROM device drivers. If the
drivers are valid, SHCDX33C will install a drive letter for each unit on
each driver.
Options
-------
/D driver and drive manipulation
/L drive letter
/C memory usage
/V memory statistics or option information
/~ tilde usage
/R read-only attribute usage
/I install
/U unload
/Q quiet
/D - Driver
This option is used to specify the name of the device driver. It can
also indicate which unit(s) should be assigned and to what letter. The
complete syntax is:
/D[:][?|*]driver[,[letter][,[unit][,[max]]]]
DRIVER is the name of the device driver installed to control the CD-ROM
drive. Prefixing the driver with '?' will silently ignore it if it does
not exist (or is not actually a CD-ROM). Prefixing with '*' will also
ignore it, but a drive will be reserved (see below).
LETTER is the first drive letter to assign to the units on this driver.
The default is the first available letter. Note: the drive letters
assigned to subsequent units will always be higher than those assigned
to previous units.
UNIT is the first unit on this driver to be assigned a drive. Unit 0 is
the default.
MAX is the maximum number of units on this driver to be assigned drives.
The default is all units (or all remaining units, if UNIT is given).
Once installed, /D by itself will display the assigned drives and return
the number of drives assigned. [NOTE: This is NOT part of SHCDX33C].
/D - Drive manipulation
At install time, /D can also be used to reserve space for additional
drives. Use a single digit to indicate how many drives should be
reserved (eg: /D1). (If you should happen to have a device driver name
with a single digit, use the '?' prefix.) After installation, the same
option will remove the drive(s) that were last assigned. It is possible
to specify both forms of /D, in which case the current drive(s) will be
removed, then the new drive(s) added.
/L - Letter
This option is an alternative to the LETTER component of /D, which it
must follow (ie: /D:driver /L:letter). It can also be used to return
the number of drives installed (/L:0, will return 255 if not installed)
and the letter of each assigned drive (/L:1, /L:2, etc., with A: = 1 and
255 if the drive is not assigned).
/C - Memory usage
By default, SHCDX33C will load itself into high memory,if available, or
into low memory if it is already high. This option will prevent that.
/V - Memory statistics
When this option is used at installation, a summary of memory usage will
be displayed. This summary includes:
Static code and variables
Dynamic data for each drive and paragraph rounding
Total overall memory usage
/V - Information
When used with /?, or after installation, this option displays the
compile- and run-time options of SHCDX33C. This information includes:
8086/386 the minimum processor required
CD root form TRUENAME will return \\D.\A.\ instead of D:\
High Sierra the original format for the CD file system
Joliet the Windows format for long names
image on CD enables access to an image which is itself on a CD
/~ - Tilde usage
The ISO standard allows for CDs to have names up to 31 characters and
Joliet can have names up to 64 characters. When this is reduced to 8.3
for DOS it may lead to duplicated entries. This option will remove the
duplication by appending a tilded number after the name (similar to what
Windows does). By default, tildes are off. This option is also avail-
able after installation. By itself it will toggle the status (ie. if
tildes are currently on, /~ will turn them off and vice versa). Tildes
can be explicitly turned on or off by adding a '+' or '-' sign (ie: /~+
will turn tildes on, irrespective of the current state).
/R - Read-only attribute usage
By default, files on the CD are given the read-only attribute. Should
you wish to remove this attribute, this option will do so. As with /~,
it can be used after installation and it accepts '+' and '-'.
/I - Install
Normally SHCDX33C will refuse to install if it detects another redirector
(such as MSCDEX). This option will cause SHCDX33C to install anyway.
[NOTE: The /I switch is NOT part of SHCDX33C].
/U - Unload
Unhook the interrupt, free the memory and mark the drive(s) as invalid.
/Q - Quiet
Prevent display of the sign-on banner (the copyright notice). /Q+ will
only display the drive assignments (when used after install '-' will in-
dicate a removed drive and '+' an added drive). |
