IRIX 6.2 Execution Only Environment CD Set

<P>
|
|
IRIX 6.2 provides a new startup script to help you prepare for installation.
|
|
This script checks for COFF programs, which will not run on IRIX 6.2. It also
|
|
checks for old kernel files and large files you may no longer need and,
|
|
with your approval, removes them. You launch the script by clicking the
|
|
``<B>OK</B>'' button in this window.
|
|
</P>
|
|
|
|
<P>
|
|
Silicon Graphics strongly recommends that you run the startup script.
|
|
</P>
|
|
|
|
<P><STRONG> Note</STRONG>: If you ran the startup script for a previous 6.2
|
|
installation, you may wish to skip it. To skip the script, click the
|
|
``<B>Cancel</B>'' button.</P>

|
How The Startup Script Works
|
|
</H4>
|
|
|
|
<P>
|
|
The startup script performs a three-part check. You can run (or skip) each
|
|
part separately. When the script finishes, it returns control to Software
|
|
Manager so that you can begin installing IRIX 6.2.
|
|
</P>

|
|
Check for COFF Programs
|
|
</H4>
|
|
|
|
<P>
|
|
IRIX 6.2 does not run COFF programs, which were built for IRIX 4.0 and
|
|
earlier releases. To determine whether any COFF programs exist, you can run
|
|
coffcheck in the first part of the startup script. (You can also quit
|
|
this installation session, reboot with your present version of IRIX, and run
|
|
coffcheck from the CDROM using the command ``<B><CODE>/CDROM/coffcheck</CODE></B>''.)
|
|
</P>
|
|
|
|
<P>
|
|
The coffcheck script identifies COFF programs on locally mounted (not NFS)
|
|
filesystems and lists these programs (and the names of other programs that
|
|
should be replaced) in one or more files for your review. Review the list
|
|
before proceeding with the installation. Do not proceed if you determine that
|
|
the lists contains necessary COFF programs for which you have no replacement.
|
|
</P>

|
Check to Increase Available Disk Space
|
|
</H4>
|
|
|
|
<P>
|
|
Because IRIX 6.2 contains a number of new products, it might require more disk
|
|
space than your current IRIX release. Silicon Graphics recommends that you
|
|
remove unnecessary files, such as old kernel crash files, program core files,
|
|
and files in user dumpsters. The second part of the startup script checks for
|
|
such files and removes them individually, as you approve each removal.
|
|
</P>
|
|
|
|
<H4>
|
|
Check for Old Kernel Files
|
|
</H4>
|
|
|
|
<P>
|
|
To insure a successful installation and kernel configuration, it is often
|
|
advisable to remove old kernel files in the
|
|
<B><CODE>/var/sysgen</CODE></B> and <B><CODE>/usr/cpu/sysgen</CODE></B>
|
|
trees. The third part of the startup script removes these old files;
|
|
any modified and custom kernel files are saved.
|
|
</P>
|
|
|
|
<P><STRONG>Note</STRONG>: You should only run this third check if you are
|
|
planning a full IRIX installation.</P>
