Nero should'nt ask you for any patches.
Nero 5.5 supports the SCSI Yamaha CRW-F1S since version 18.104.22.168c according to http://www.nero.com/en/632012038142166. ... HA&lang=en
what is your version of Nero 5.5 ? if it's older than 22.214.171.124 this could be the problem.
it shouldn't matter to nero if your CD burner is a "normal" one (IDE) or it's a SCSI one.
try uninstalling Nero and reinstalling the latest version 126.96.36.199 from here: http://www.nero.com/en/631933457317970.html
