Running Microsoft Windows 95/NT Applications

Running Windows 95 From CD-ROM

Windows 95 cannot be installed with the “Run From CD-ROM” option. Use any of the other options.

SunPCi Appears to Hang When Browsing Network Drives

If you are running Solaris 2.6 on your workstation, you may observe a very long time lag when browsing network drives. SunPCi may even appear to hang as it searches the contents of the drives. This is a feature of Solaris 2.6 and Solaris 7.

Solaris 2.6 contains a “browsing” feature that allows you to automatically view all automount points on your workstation. In Solaris 2.5.1 and earlier versions, automounted directories are not visible until they have been mounted.

This may cause Windows 95/NT applications to slow down considerably when browsing for files on your workstation (especially on your R: drive, which is /), and may cause problems when viewing very large directories with Windows Explorer or saving to a subdirectory in one of these directories.

You can turn off this problem by editing the Solaris 2.6 auto_master file. To edit this file, perform the following steps:

  1. Use a text editor to open the file /etc/auto_master.

    The file should look similar to the following: 

    # Master map for automounter#+auto_master/net	-hosts					-nosuid,nobrowse/home	auto_home					-nobrowse/xfn	-xfn

  2. Move the +auto_master line in the file to the bottom of the list, after -nobrowse. If the -nosuid, nobrowse and -nobrowse keywords are not present in the file, add them.

    The result should look similar to the following: 

    # Master map for automounter#/net	-hosts					-nosuid,nobrowse/home	auto_home					-nobrowse/xfn	-xfn+auto_master

  3. Save the file and exit the text editor.

  4. Reboot your system.

    The “browsing” feature should be turned off.

Displaying Shortname Tails

When the DOS window reads a Windows 95/NT-style long file name, it truncates the long name into DOS format (that is, an eight-character file name followed by a three-character extension) and adds a number to the file (such as ~1); this number is called a shortname tail. When reading long file names on extended drives in the Windows 95 DOS window or the Windows NT Command window, the window can only display shortname tails ending in the number 1; it cannot display ~2, ~3, and so on.

Note –

The term “DOS window” refers to the DOS shell window that you access from Windows 95 (called the Command Window in Windows NT. It does not refer to DOS windows running under OpenDOS 7.01.

Reading Windows Formatted CDs

Note –

This section refers to Windows 95 only. If you are running Windows NT, skip this section.

Some versions of Solaris (Solaris 2.5.1 and 2.6) are unable to read some Windows formatted CDs, such as the RockRidge format. If SunPCi cannot read a CD you are trying to use, check the contents of the CD as described in the following procedure.

  1. Open a Command Tool window on the Solaris desktop.

    Enter the following commands: 

    % cd /cdrom/cdrom0
% ls -lR

    If the system responds with a message similar to the following, it is unable to read the setup file from your CD:

    ./setup.exe: No such file or directory

    total 170

    -r-xr-xr-x 1 root sys 45 Aug 21 1996 autorun.inf*

    dr-xr-xr-x 2 root sys 2048 Nov 26 11:46 doc/

    -r-xr-xr-x 1 root sys 11171 Nov 25 10:01 readme.txt

    dr-xr-xr-x 2 root sys 2048 Nov 26 11:46 setup/

If this happens, you will need to download and install a Solaris patch. Instructions for installation are included with the patch. You can find the patches at http://access1.sun.com.

The SunPCi Installation Guide contains instructions on how to install the patches, which are also included on the SunPCi software CD.

Network Neighborhood

When you open the Network Neighborhood on the Windows 95/NT desktop, the Network Neighborhood window does not show My Workstation. The workstation and the SunPCi card share the same network interface, so they do not “see” each other on the network. Both can communicate with the network, however.

For more information on networking your workstation with your SunPCi host, refer to Networking With SunPCi.

International Keyboard Support

Note –

This section refers to DOS and Windows 95. If you are running Windows NT, skip this section.

DOS uses the file C:\dos\keyb.com as its keyboard driver. However, Windows 95 uses the file C:\windows\keyb.com. This results in the loss of support for international keyboards when you use Windows 95.

The following procedure explains how to modify your autoexec.bat and config.sys files to use the DOS keyboard driver for international support.

For more information on international support, refer to Appendix B, SunPCi International Support.

To restore support for international keyboards, follow this procedure:

  1. In the SunPCi window, click the Start button, and then select Programs and then Accessories from the pop-up menus.

  2. Select Notepad, and then open your C:\autoexec.bat file.

  3. Add the following line to the file: 

    C:\dos\keyb.com

  4. Save the file and close it.

  5. Open your C:\config.sys file.

    The following line may appear:

    rem DEVICE=C:\DOS\SETVER.EXE

    If it does appear, remove the rem (remark) statement and save the file.

    If it does not appear, add the line DEVICE=C:\DOS\SETVER.EXE to the file and then save it.

  6. Exit Notepad.

  7. Click the Start button and then select Shut Down from the pop-up menu.

    The Shut Down Windows dialog box appears.

  8. Select Restart the computer in MS-DOS mode and then click Yes to reboot SunPCi.

    When SunPCi has finished rebooting, the MS-DOS prompt appears in the SunPCi window.

  9. Enter the following commands at the DOS prompt: 

    C:\> CD DOS
C:\> SETVER keyb.com 7.01
C:\> win

    This sets the keyboard driver to the proper version and starts Windows 95.

You will need to enter the CD DOS and SETVER commands every time you start SunPCi. You may want to configure your SunPCi system to automatically boot to the DOS prompt each time. Refer to Appendix C, SunPCi Performance Tips for instructions on how to configure your system.
