56 Getting Started with PowerPC Open Firmware
Replace the Logo Bitmap
You may flash an OEM logo bitmap into ROM in order to
supersede the default Motorola logo bitmap. The NVRAM variable
mot-oem-logo? is used to choose between the default logo and the
OEM logo. This variable defaults to false.
The bitmap Þle must be in the standard (uncompressed) 256-color
Microsoft Windows .bmp format. The image should be 300 pixels
wide by 75 pixels high. If this area is too large, fill in the unused
pixels with the background color (index $13).
Choose this option to add a user-deÞned logo to PowerPC Open
Firmware.
1. Have a floppy disk ready that contains the new logo bitmap
file. The file must be properly formatted and stored on a DOS-
formatted floppy disk with the filename oemlogo.bmp.
2. Using the keyboard or mouse, select the Replace the Logo
Bitmap from the Update the Firmware menu.
3. The following prompt is displayed:
Insert Floppy Disk Containing New Logo Bitmap
Proceed? (Y/N)
4. To proceed, insert the floppy disk containing the new logo
into the floppy drive, enter Y and press <ENTER>, or enter N
to bypass the process and return to the Update the Firmware
menu.
5. If you enter a Y and the firmware is running on a
MVME2600/3600 Series product, continue with step 6. For all
other products skip to step 7.
6. Firmware running on a MVME2600/3600 Series product
displays the following prompt:
