- The InVircible Utilities
- ------------------------
- The utilities in this package are rarely used in IV's daily operation.
- Yet they facilitate performing certain tasks, that otherwise may
- require the use of an ASCII editor or of a disk management utility.
-
- NOCMOS
- ------
- The CMOS setup parameters are backed up by InVircible the first time
- IVINIT runs from the autoexec. On every subsequent booting, the current
- CMOS configuration parameters are compared by IVINIT to those stored in
- the CMOS.NTZ file. If a change in configuration is detected, then the
- user is alerted.
-
- There are instances where multiple CMOS configurations are used, for
- example with notebooks, when docked or as a stand alone machine. In
- these cases the user may wish not to be bothered with the CMOS check
- every time the computer is booted. IVINIT will skip the CMOS test when
- invoked with the /NOCMOS switch.
-
- The NOCMOS utility edits the C:\AUTOEXEC.BAT file to enable, or disable
- the IVINIT CMOS test. Running NOCMOS E will enable the CMOS test, while
- running NOCMOS D will disable the CMOS test in the autoexec.
-
- FIND-SIG.
- ---------
- InVircible creates an integrity database that consists of a signatures
- file in each directory that contains binary-executable files. The
- filename of these signatures may contain high ASCII (unprintable)
- characters. Especially if the installation of IV was performed with
- IVLOGIN, with the random filename option ON (IVLOGIN /RANDOM). The
- purpose of the hi-ascii characters in the filename is to protect the
- database from being accidentally erased. The first three characters of
- the signature filename are always printable alphanumerics, so that they
- can be handled from DOS, when using the "?,*" wildcards.
-
- Many users depend on Windows and on its file manager. To their dismay,
- Windows is unable to handle files which's name contains high ascii
- characters. Most users ignore that Windows is handicaped in this
- aspect. If you read this file wth a DOS viewer then you'll be able to
- see in the following "αßΓπ" the sequence of four Greek characters
- starting with alpha (ASCII 224). Yet under windows you probably see
- only underscores, or maybe just one character, but not all four.
-
- FIND-SIG is a housekeeping utility. It will find and remove inactive or
- orphan IV signature files which you may have lost for whatever reason.
- Just type FIND-SIG and the drive name that you wish to scan (the
- default is the current drive). FIND-SIG will prompt the user on any IVB
- inactive signature file that it finds and ask if to skip the file,
- erase it, or erase all the orphan IVB files that it finds.
-
- FIND-SIG can also be used to cleanup periodically from the IVB.000
- backup signatures. Another usage of FIND-SIG is to remove all IVB
- signatures left after uninstalling InVircible from a computer.
-
- GET-HD
- ------
- GET-HD will display the CMOS setup and the IDE parameters of the two
- first hard drives installed in a computer. For SCSI and MFM drive it
- will display the hard drive parameters found in the BPB (bios
- parameters block). The parameters shown by GET-HD are written in the
- HD_DATA.NTZ file, created on the rescue diskette at the time of its
- preparation.
-
- These parameters can be useful in disaster recovery scenarios or when
- asking for assistance from the IV online support.
