Start Up / Shut Down Graphic Instructions

Please Note: The Standard Disclaimer applies here. Make any changes to your system at your own risk. If you are not comfortable working in DOS, or changing your .sys files --- don't do it. No Joke is more important than your peace of mind.

How It Works

When Windows 95 is booted the system checks to see if the start-up logo should be displayed. It does this by consulting the file MSDOS.SYS. This is a text file that allows various boot options to be specified. There are two entries in this file that determine whether the start-up logo is displayed. First, the entry 'BootGUI=1' tells the system to start the GUI interface. If this value is 0 only the command line interface (DOS) is started. Secondly, the entry 'Logo=1' tells the system to display a start-up graphic. Since this is the default, the entry doesn't have to be written in MSDOS.SYS! If the value is 0 then the GUI is booted without displaying the start-up logo.

If the system determines that a start-up logo is to be displayed it attempts to display the file C:\LOGO.SYS. If this file is not found then a default start-up graphic that is embedded in IO.SYS is displayed. The purpose of C:\LOGO.SYS appears to be to allow for local customizations, language or otherwise. This is most visible to those users who have installed the Plus! Pack. During the installation of the Plus! Pack, a new C:\LOGO.SYS is written which contains the Plus! logo.

When Windows 95 is shut down, it displays two logos. The first tells the user to wait whilst the system completes all necessary housekeeping, such as writing any necessary information to disk. This logo is contained in the file LOGOW.SYS. The second logo tells the user that it is safe to switch off the computer. This logo is contained in the file LOGOS.SYS. Both these files are stored in the same directory as the Windows 95 installation. For the majority of users this will be C:\WINDOWS.

It is a fundamental requirement that the three files LOGO.SYS, LOGOW.SYS, and LOGOS.SYS all have the following properties:

1. The file is stored as a Windows Bitmap. Despite the '.SYS' extension, the file is really a '.BMP' in disguise.

2. The size of the logo is 320 pixels wide by 400 pixels high.

3. The color depth is 8 bits per pixel. In other words, it's a 256 color bitmap.

4. The file size is exactly 129,078 bytes.


How to create a custom graphic using Microsoft tools

What you need:

1. Microsoft Internet Explorer version 2.0 or later. You can obtain the latest version from Microsoft. Internet Explorer allows you to save a JPEG or GIF file as a 256 color BMP.

2. Microsoft Paint as delivered with Windows 95

To download a graphic:

1. Select the graphic to view in Internet Explorer.

2. Right-click on the displayed image.

3. Select the "Save Picture As" menu option.

4. In the "Save As" dialog, select "BMP bitmap" for the file type.

5. Confirm the dialog to save the bitmap.

To resize the downloaded graphic:

These instructions assume that the downloaded file is 640x480 pixels. If you downloaded a graphic that is pre-sized to 320x400, you may skip steps 1 through 6 below. If your downloaded file is a different size then adjust the ratios accordingly.

1. Open the bitmap file using MS-Paint.

2. Select the Image/Stretch menu option.

3. In the 'Stretch and Skew' dialog: select the Horizontal button in the Stretch group box and change the value from 100% to 50%. OK the dialog.

4. Again, open the 'Stretch and Skew' dialog this time selecting the Vertical button in the Stretch group box. Change the value from 100% to 84%. OK the dialog.

5. Select the Image/Attributes menu option. Change the Height from 404 to 400. OK the dialog.

6. Save the bitmap.

To make the graphic the start-up logo:

1. Optional: Make a backup of the existing logo. Copy the file C:\LOGO.SYS to C:\LOGO.BAK, or some other name you prefer. If C:\LOGO.SYS cannot be found on your system do not panic, simply proceed to the next step.

2. Copy or rename your bitmap to C:\LOGO.SYS.

To make the graphic the first shutdown logo:

1. Determine which directory contains your Windows 95 installation. For most users this will be C:\WINDOWS. In this directory you should find the file LOGOW.SYS.

2. Optional: Make a backup of the existing logo. Copy LOGOW.SYS to LOGOW.BAK, or some other name you prefer.

3. Copy or rename your bitmap to LOGOW.SYS.

To make the graphic the second shutdown logo:

1. Determine which directory contains your Windows 95 installation. For most users this will be C:\WINDOWS. In this directory you should find the file LOGOS.SYS.

2. Optional: Make a backup of the existing logo. Copy LOGOS.SYS to LOGOS.BAK or some other name you prefer.

3. Copy or rename your bitmap to LOGOS.SYS


Using Non-Microsoft Tools

Since there are numerous browsers and graphics editing tools it is impossible to give instructions to cover all. The instructions given for the Microsoft tools should serve as a good starting point. The important thing is to aim to create a 320x400 256-color Windows bitmap. If you get stuck, consult the help section for assistance or use the Microsoft tools (these are known to work).


Limitations

1. The size and format of a logo cannot be changed.

2. Depending upon the original graphic and the tools used. When you resize a 640x480 graphic down to 320x400, some bits get 'chopped' out and the result can appear quite fuzzy or block-like when stretched to full-screen. The best results tend to come from those files that are 320x400 to begin with.

3. Some start-up graphics may appear with a white border.

4. The progress indicator (whirly bar at the bottom of the image), present on the Microsoft start-up logo will be missing. Do not immediately assume that the system is not responding.


Help/FAQ section

1. I can't find the file C:\LOGO.SYS

2. I can't find any of the logo files.

3. My new logo doesn't work! I still get the old one!

4. My new logo doesn't work! I get nothing or a garbled screen.

5. How can I tell if the format of the file is wrong?

6. I've checked the file using MS-Paint. It's 320x400 pixels and uses color. I still won't display. What's wrong?

7. Can I examine the file directly to see if it's correct?

8. Can I change the default start-up graphic that is embedded in the file IO.SYS?

9. I didn't make backup copies of the Microsoft logos. How can I get them back?
