6.10 Installation over the AsTeX distribution 

The installation can be done in a number of ways, according to the hardware configuration of your PC (number of available CD-ROM drives, free room on the hard disks, possibility or not to use a network disk if the PC is networked). There are too many various possibilities to enumerate them all, only some examples of configurations are described below:

1.  A stand-alone PC with two CD-ROM drives (for example a DVD drive and a CD-recorder)  : you can install both CD-ROMs in Plug & Play mode, for a super-fast installation.
2.  A stand-alone PC with a CD-ROM drive and a lot of room on the hard disk: copy one of the CD-ROMs on the hard disk in a directory, for example C:\astexcd, create a virtual CD-ROM drive by adding the line

   subst T: C:\astexcd

   in the file autoexec.bat (Windows 9x) or in a file inidv.bat (Windows NTx) placed in the Starting directory of the user or of All Users and perform the installation in Plug & Play mode from the two drives (physical and virtual).
3.  A standalone PC with a lot of room on the hard disk: copy both CD-ROMs each in its directory, for example Copies of CD\AsTeX and Copies of CD\Rosetta, create two virtual CD-ROM drives by adding the lines

   subst T: "Copies of CD\AsTeX"  subst V: "Copies of CD\Rosetta"

   in the file autoexec.bat or inidv.bat as above, and perform installations in Plug & Play mode from drives T: and V:.

   Remark : normally, it ought to be also possible to copy the two CD-ROMs in the same directory, in order to use only one drive name (DVD mode, to be tested).

4.  If your PC is networked, you can use a network CD-ROM drive (that means a CD-ROM drive of another PC shared through the network to which you are connected).
5.  If you have several hard disks and not enough room on only one hard disk but enough on two, the virtual CD-ROM drives can lie also on distinct hard disks: the location of the AsTeX CD-ROM is known of the AsTeX and Rosetta distributions through the environment variable ASTEXBAS, the one of the Rosetta CD-ROM through the variable ROSETBAS, the content of these two variables being possibly identical (DVD mode) or distinct (present case).

   On the other hand, the kernel of the two distributions must be put together, and its location is known of the two distributions through the environment variable ASTEXDIR. The kernel of Rosetta only adds 0.1 Mo to the kernel of AsTeX. If you install the Rosetta distribution on an existing AsTeX installation, there should not be any problem: the installation program of Rosetta should detect it and should install the kernel of Rosetta with the kernel of AsTeX.

   If you installed only the Rosetta distribution and that you want to install the AsTeX distribution also (for example to display the dvi versions of certain manuals, or to use other programs of AsTeX), it is necessary to install it so that it shares the same main directory with the Rosetta distribution on the hard disk (c:\ast if you used the directory by default for Rosetta, the main directory associated to ASTEXDIR if you defined this variable as indicated in the section 6.6).
