Agreed. I've made copies of my original SunOS 4.1.1 CD onto CD-R, and 
they work fine.

It's not that CD itself has 512 byte sectors, it's the Sun drives that 
present the data in 512 byte sectors. (and we're talking about pretty 
old drives, the openboot prom in anything newer than (probably) 1st 
generation SPARC boxes should be able to boot off a CD-ROM drive that 
doesn't support the 512 byte sector mode.
