I installed Suse 9.1 home from downloaded CDROM's , upgraded it to 9.1 professional via the Suse website and then upgraded it again to 9.2 Professional from the downloaded DVD.
The Bootsplash screen was not working. After a bit of digging I found that the file '/etc/sysconfig/bootsplash' contained the line 'Theme="SuSE-Home" but that the SuSE-Home theme (bootsplash-theme-SuSE-Home.rpm) was no longer installed.
I did have the SuSE Professional theme (bootsplash-theme-SuSE) installed though so I edited the line to read 'Theme="SuSE"' which matched the name in the '/etc/bootsplash/themes' directory.
I executed mkinitrd which attached the appropriate image to the initrd and everything is sweet now.
