E Sdrviewer Splash Screen File Format - Intel SR870BN4 - Server Platform - 0 MB RAM Product Manual

E SDRViewer Splash Screen File Format

The splash screen file contains a header and binary data that holds the Unicode characters and their
color attributes that are displayed on the screen. The default file name extension of the splash
screen files is *.sph. Table 62 summarizes the content of these files.
NOTES
The last character in the screen cannot be displayed, because it causes the
screen to scroll up. Even though it is required in the file, it is not written to
the screen.
The utility checks that the text mode resolution specified in the splash screen
file is supported by the system. The splash screen is not displayed if the text
mode is not supported. In addition, the current text mode is preserved after
the splash screen is successfully displayed.
