But FC2 did work on the same machine, and the test sound was fine.

I' ve done that now and the boot process stopped at the same point. No 
change at all. I have then added the original lines back into the file 
(was I supposed to do that?) and went on to the next suggestion:

Yes, it did. the last line before the boot process hung now reads:

Initializing hardware... IDE:Gerhard storage network audio

Unfortunately, it still hangs at that point.

So far that was not too complex. Thanks for trying to help. I wonder 
what else I could try?

Having said that, what could be the reason that FC2 worked, and FC3 
doesn't? I installed FC2 only very recently, on this Tecra laptop which 
had been set up for dual-booting Windows 98 and some older version of 
Suse linux. I chose to remove all Linux installations (because I wanted 
to get rid of Suse. A few days later FC3 was released and I did not 
spend any more time with FC2. Could there be a problem with the 
partitions and this bootloader program which interferes with the 
operating systems? Windows seems to take forever as well to start up 
(well, even longer than I remember it doing).

Anyway, any help is appreciated.
