I am having problems creating bootable CDs from the disc1.iso files.  It 
is likely that I've overlooked something.  But, I cannot guess what it is 
and I'm hoping you can help.

Normally, I do

cdrecord xxxxx.disc1.iso

I have a cdrecord.conf file which sets up the device parameters and I've 
used this cdrecord.conf for several years now.  But, none of the CDs I've 
burned lately seem to be boot.  Have I forgotten some special flag for 
cdrecord?

Thanks! Ken
