This document describes the steps for inserting a custom logo or splash screen into the BIOS for Intel® Desktop Boards based on the Intel® 845 chipset. If you wish to customize the splash screen on Intel® Desktop Boards with Intel® 865 chipsets and later, refer to Intel® Integrator Toolkit Technical Support.
Step One: Create the Logo File
Create the Original Image
There are any number of ways to create the desired original image: Scan in a company logo; create the image using a graphics software such as PhotoShop* or Paint*; import an image from a digital camera.
Important Notes:
- A maximum of 478 (rows) x 638 (columns) pixels work best.
- It is possible to make the image too complex and exceed the maximum file size. It's best to use a simple graphic.
- The completed image must be saved as a 16-color bitmap (for example: MYLOGO.BMP).
Download the Splash Utility
- Download SPLASH07.EXE and save it in a working directory like C:\SPLASH.
- Extract SPLASH07.EXE and then extract SW.EXE. You should now have the file needed, SPLASH.EXE.
Create the .USR File
- Copy the image file you created into the same directory as SPLASH.EXE. (In this example, we'll use the filename MYLOGO.BMP.)
- Go to the command prompt and navigate to the directory containing SPLASH.EXE and the image file.
- Run the following command line to create the .USR file: (The switches, /__, are case sensitive):
- SPLASH /s12 /lsp /jc /bg /FuMYLOGO.USR MYLOGO.BMP
- For more information on available command line switches, read the SPLASH.TXT.
Step Two: Flash the Logo File Into BIOS
Prepare Iflash Floppy Diskette
- Download the Iflash BIOS utility for your desktop board to a working directory and double-click the filename to extract the update files.
- Double-click SW.EXE to extract additional update files into the working directory. Note: Depending on board model, SW.EXE may not be present; if this is so, skip this step.
- Double-click the file RUN.BAT to create the BIOS update floppy diskette. Follow on all screen directions.
- Copy IFLASH.EXE from the working directory to the floppy diskette.
- Copy the image file you previously created to the floppy diskette (in this example: MYLOGO.USR).
- On the floppy diskette, rename the AUTOEXEC.BAT to AUTOEXEC.BAK.
Update the BIOS
- Insert the floppy diskette into the floppy drive and turn on the PC. Press Enter until the A:\ prompt appears.
- Type IFLASH and press Enter.
- Choose Update flash memory area from a file.
- Choose Update User data area.
- Press the down arrow to select the MYLOGO.USR file.
- Press Enter twice to begin the flash update. DO NOT interrupt the flash update process.
- When the update is complete, remove the floppy diskette and restart the computer.
Note: Quiet Boot must be enabled in BIOS to view the new logo. Rapid Boot may need to be disabled to see it for any length of time.
Troubleshooting
Iflash Update Reports Error When Attempting to Change Logo
The following errors occur when trying to install a 4KB .USR file into a BIOS that requires a 12KB file:
(H31): Logical area size does not match BIOS.
(H01): The flash data image read from disk was found to be not valid.
Error: Flash update was unsuccessful.
Intel® Desktop Boards require the .USR file for custom logos be compiled to a 12KB size before the Iflash utility can update the user data area with the new splash screen.
To ensure the file is compiled to 12KB, the Splash Screen utility command line must include the /s12 switch, as in this example:
SPLASH /lsp /jc /bg /s12 /FuMYLOGO.USR /display MYLOGO.BMP
Note: Older Intel® Desktop Boards (that are not listed below) may require a .USR file size of 4KB. The default file size for the Splash screen utility is 4KB, so by omitting the /s12 command line switch or altering it to reflect /s4, a 4KB .USR file will be generated.
