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 "рсту" 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.
