-** SCO Unix and UnixWare
-
-*** SCO 3.2v4: Unusable default font.
-
-The Open Desktop environment comes with default X resource settings
-that tell Emacs to use a variable-width font.  Emacs cannot use such
-fonts, so it does not work.
-
-This is caused by the file /usr/lib/X11/app-defaults/ScoTerm, which is
-the application-specific resource file for the `scoterm' terminal
-emulator program.  It contains several extremely general X resources
-that affect other programs besides `scoterm'.  In particular, these
-resources affect Emacs also:
-
-        *Font: -*-helvetica-medium-r-*--12-*-p-*
-        *Background:                    scoBackground
-        *Foreground:                    scoForeground
-
-The best solution is to create an application-specific resource file for
-Emacs, /usr/lib/X11/sco/startup/Emacs, with the following contents:
-
-        Emacs*Font:     -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
-        Emacs*Background:       white
-        Emacs*Foreground:       black
-
-(These settings mimic the Emacs defaults, but you can change them to
-suit your needs.)  This resource file is only read when the X server
-starts up, so you should restart it by logging out of the Open Desktop
-environment or by running `scologin stop; scologin start` from the shell
-as root.  Alternatively, you can put these settings in the
-/usr/lib/X11/app-defaults/Emacs resource file and simply restart Emacs,
-but then they will not affect remote invocations of Emacs that use the
-Open Desktop display.
-
-These resource files are not normally shared across a network of SCO
-machines; you must create the file on each machine individually.
-
-*** Regular expressions matching bugs on SCO systems.
-
-On SCO, there are problems in regexp matching when Emacs is compiled
-with the system compiler.  The compiler version is "Microsoft C
-version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
-C Compiler Version 1.00.46 (Beta).  The solution is to compile with
-GCC.
-
-*** UnixWare 2.1: Error 12 (virtual memory exceeded) when dumping Emacs.
-
-Paul Abrahams (abrahams@acm.org) reports that with the installed
-virtual memory settings for UnixWare 2.1.2, an Error 12 occurs during
-the "make" that builds Emacs, when running temacs to dump emacs.  That
-error indicates that the per-process virtual memory limit has been
-exceeded.  The default limit is probably 32MB.  Raising the virtual
-memory limit to 40MB should make it possible to finish building Emacs.
-
-You can do this with the command `ulimit' (sh) or `limit' (csh).
-But you have to be root to do it.
-
-According to Martin Sohnius, you can also retune this in the kernel:
-
-    # /etc/conf/bin/idtune SDATLIM 33554432         ## soft data size limit
-    # /etc/conf/bin/idtune HDATLIM 33554432         ## hard "
-    # /etc/conf/bin/idtune SVMMSIZE unlimited       ## soft process size limit
-    # /etc/conf/bin/idtune HVMMSIZE unlimited       ## hard "
-    # /etc/conf/bin/idbuild -B
-
-(He recommends you not change the stack limit, though.)
-These changes take effect when you reboot.

-** Problems running Perl under Emacs on MS-Windows NT/95.
-
-`perl -de 0' just hangs when executed in an Emacs subshell.
-The fault lies with Perl (indirectly with Windows NT/95).
-
-The problem is that the Perl debugger explicitly opens a connection to
-"CON", which is the DOS/NT equivalent of "/dev/tty", for interacting
-with the user.
-
-On Unix, this is okay, because Emacs (or the shell?) creates a
-pseudo-tty so that /dev/tty is really the pipe Emacs is using to
-communicate with the subprocess.
-
-On NT, this fails because CON always refers to the handle for the
-relevant console (approximately equivalent to a tty), and cannot be
-redirected to refer to the pipe Emacs assigned to the subprocess as
-stdin.

-A workaround is to modify perldb.pl to use STDIN/STDOUT instead of CON.

+**** Irix 5.2: unexelfsgi.c can't find cmplrs/stsupport.h.
+
+The file cmplrs/stsupport.h was included in the wrong file set in the
+Irix 5.2 distribution.  You can find it in the optional fileset
+compiler_dev, or copy it from some other Irix 5.2 system.  A kludgy

+
+**** Irix 5.3: "out of virtual swap space".
+
+This message occurs when the system runs out of swap space due to too
+many large programs running.  The solution is either to provide more
+swap space or to reduce the number of large programs being run.  You
+can check the current status of the swap space by executing the
+command `swap -l'.
+
+You can increase swap space by changing the file /etc/fstab.  Adding a
+line like this:
+
+/usr/swap/swap.more     swap    swap    pri=3 0 0
+
+where /usr/swap/swap.more is a file previously created (for instance
+by using /etc/mkfile), will increase the swap space by the size of
+that file.  Execute `swap -m' or reboot the machine to activate the
+new swap area.  See the manpages for `swap' and `fstab' for further
+information.
+
+The objectserver daemon can use up lots of memory because it can be
+swamped with NIS information.  It collects information about all users
+on the network that can log on to the host.
+
+If you want to disable the objectserver completely, you can execute
+the command `chkconfig objectserver off' and reboot.  That may disable
+some of the window system functionality, such as responding CDROM
+icons.
+
+You can also remove NIS support from the objectserver.  The SGI `admin'

+
+*** SCO Unix and UnixWare
+
+**** SCO 3.2v4: Unusable default font.
+
+The Open Desktop environment comes with default X resource settings
+that tell Emacs to use a variable-width font.  Emacs cannot use such
+fonts, so it does not work.
+
+This is caused by the file /usr/lib/X11/app-defaults/ScoTerm, which is
+the application-specific resource file for the `scoterm' terminal
+emulator program.  It contains several extremely general X resources
+that affect other programs besides `scoterm'.  In particular, these
+resources affect Emacs also:
+
+        *Font: -*-helvetica-medium-r-*--12-*-p-*
+        *Background:                    scoBackground
+        *Foreground:                    scoForeground
+
+The best solution is to create an application-specific resource file for
+Emacs, /usr/lib/X11/sco/startup/Emacs, with the following contents:
+
+        Emacs*Font:     -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
+        Emacs*Background:       white
+        Emacs*Foreground:       black
+
+(These settings mimic the Emacs defaults, but you can change them to
+suit your needs.)  This resource file is only read when the X server
+starts up, so you should restart it by logging out of the Open Desktop
+environment or by running `scologin stop; scologin start` from the shell
+as root.  Alternatively, you can put these settings in the
+/usr/lib/X11/app-defaults/Emacs resource file and simply restart Emacs,
+but then they will not affect remote invocations of Emacs that use the
+Open Desktop display.
+
+These resource files are not normally shared across a network of SCO
+machines; you must create the file on each machine individually.
+
+**** SCO 4.2.0: Regular expressions matching bugs on SCO systems.
+
+On SCO, there are problems in regexp matching when Emacs is compiled
+with the system compiler.  The compiler version is "Microsoft C
+version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
+C Compiler Version 1.00.46 (Beta).  The solution is to compile with
+GCC.
+
+**** UnixWare 2.1: Error 12 (virtual memory exceeded) when dumping Emacs.
+
+Paul Abrahams (abrahams@acm.org) reports that with the installed
+virtual memory settings for UnixWare 2.1.2, an Error 12 occurs during
+the "make" that builds Emacs, when running temacs to dump emacs.  That
+error indicates that the per-process virtual memory limit has been
+exceeded.  The default limit is probably 32MB.  Raising the virtual
+memory limit to 40MB should make it possible to finish building Emacs.
+
+You can do this with the command `ulimit' (sh) or `limit' (csh).
+But you have to be root to do it.
+
+According to Martin Sohnius, you can also retune this in the kernel:
+
+    # /etc/conf/bin/idtune SDATLIM 33554432         ## soft data size limit
+    # /etc/conf/bin/idtune HDATLIM 33554432         ## hard "
+    # /etc/conf/bin/idtune SVMMSIZE unlimited       ## soft process size limit
+    # /etc/conf/bin/idtune HVMMSIZE unlimited       ## hard "
+    # /etc/conf/bin/idbuild -B
+
+(He recommends you not change the stack limit, though.)
+These changes take effect when you reboot.

+*** MS-Windows NT/95: Problems running Perl under Emacs
+
+`perl -de 0' just hangs when executed in an Emacs subshell.
+The fault lies with Perl (indirectly with Windows NT/95).
+
+The problem is that the Perl debugger explicitly opens a connection to
+"CON", which is the DOS/NT equivalent of "/dev/tty", for interacting
+with the user.
+
+On Unix, this is okay, because Emacs (or the shell?) creates a
+pseudo-tty so that /dev/tty is really the pipe Emacs is using to
+communicate with the subprocess.
+
+On NT, this fails because CON always refers to the handle for the
+relevant console (approximately equivalent to a tty), and cannot be
+redirected to refer to the pipe Emacs assigned to the subprocess as
+stdin.
+
+A workaround is to modify perldb.pl to use STDIN/STDOUT instead of CON.
