SHCDX33c /D:SHSU-CDN,Z 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).
