Thank you. THAT sounds (sounded) very promising.
After quite some effort I finally found out, how to make my drive burn 
slower. The lowest I could achieve was 8x.
BUT ... this disk is also not recognized.
I set the BIOS to read from CD-ROM first. Does not help.

In response to someones question about equipment.
I used the same equipment for buring the "9.04" (which boots) and the 
"10.4" (or 9.10; which does not boot regardless of whether is has been 
burned at 48x or at 8x)
Could it be, that the empty CD itself (brand) could be responsible??
