for the first time in a while, i wanted to burn a few CDs (FC2-test1,
no big surprise there). i'm running FC1, and booting *without* the SCSI
emulation feature on my inspiron 8100 with built-in ATAPI CD-RW.
just to make sure the CD writer is properly recognized, i do:

looks good. then, to burn, i run:
# cdrecord -v dev=ATAPI:/dev/hdb disc1.iso
what i get (consistently, that is, five coasters in a row now) is:
