- Utility of the Month: STARTUP.BAT
-
- Have you ever wanted to change the screen Microsoft Windows 3.0 displays when
- you start it? With STARTUP, you can create your own Windows start-up screen.
- After you create your screen and save it in 4-bit RLE format (more about that
- later) simply type:
-
- STARTUP rleimage[.rle] [/e] [d:\winpath\]
-
- from the DOS prompt. Replace the above "rleimage[.rle]" with the name of your
- RLE-4 format graphics screen. The .RLE extension is not necessary.
-
- If you are using an EGA monitor, follow the RLE file with a "/e" switch. If
- Windows is installed on a drive or directory other than the current one, enter
- the name of the path after the RLE file name for VGA systems or after the "/e"
- switch for EGA systems.
-
- Be sure to end the directory name with a \ character if other than the default
- directory of the Windows drive!
-
- Example:
-
- STARTUP mystart /e c:\windows\
-
- or ...
-
- STARTUP mystart.rle d:
-
-
- How it Works:
-
- Each time you install Windows, STARTUP creates a file called WIN.COM. This
- is the program that runs when you type "WIN" to load Windows. WIN.COM is an
- essential housekeeping program that does several important tasks such as
- finding the path where Windows is located, checking for the existance of
- HIMEM.SYS and any Extended Memory Managers, loading PROGMAN.EXE, and -- of
- course -- displaying Microsoft's logo screen.
-
- All the STARTUP does to create this file is to combine three files: a program
- loader called WIN.CNF, a logo display routine (called variously VGALOGO.LGO,
- EGALOGO.LGO, CGALOGO.LGO, EGAMONO.LGO or HERCLOGO.LGO depending on your
- system configuration) and the start-up screen's graphics file, named as the
- display routine, but ending with the extension .RLE (Run-Length Encoded 4-bit
- -- a graphics file format). These files are saved in the SYSTEM subdirectory
- of your Windows directory. SETUP just copies these files, one after the
- other, into one single file called WIN.COM.
-
- STARTUP creates a NEW WIN.COM for you. If you ever want to switch BACK to
- the old WIN.COM, just run STARTUP and tell it to use VGALOGO.RLE, located in
- the SYSTEM subdirectory of your Windows directory. Example:
-
- STARTUP C:\WINDOWS\SYSTEM\VGALOGO.RLE
-
- It's that simple!
-
- NOTE: If you are running Windows on a system with a graphics adapter other
- than EGA (Color) or VGA, you may add your own support by loading STARTUP.BAT
- into a text editor and changing all occurrences of "VGALOGO.LGO" to the name
- of the graphics loader file mentioned above that corresponds to your setup.
-
- Creating RLE Files:
-
- If you want to make your OWN RLE file, just create a graphics file no larger
- than 640 x 480 (640 x 250 for EGA systems) in Windows Paint or other suitable
- paint program. The image may have no more than 16 colors. Save it as a BMP
- or GIF file (if your paint program allows GIF format).
-
- Next, you must get a graphics conversion program such as the excellent WinGIF
- or Paint Shop utilities (found on most bulletin-board systems or available
- from many Shareware vendors). Load the BMP or GIF file and immediately save
- it again, selecting the "Format RLE" or "Format RLE 4" option. That's it!
- You now have a suitable RLE file for use as a start-up screen. You can also
- use this procedure to convert existing graphics files you may have downloaded
- or received on disk.
-
- IMPORTANT NOTE: If the image is too complex and the file is too large (over
- about 55k), it will not display properly or you will receive a "Program too
- large to fit in memory" error when you try to run Windows. If this happens,
- load the file back into your paint program or conversion utility and try to
- "dither" it to a smaller palette size or resize it to fit into a smaller area
- and then center it in a solid background. Read the documentation for your
- conversion utility or paint program for more information on how to do this.
- Some files may not be useable as start-up screens for this reason.
-
- Once you've created your own start-up screens, you'll never want to go back
- to Microsoft's plain vanilla start-up again!
