Nope. What You say was valid for some old 700 series machines (AFAIR 715
etc). Even the older C-Class machines boot fine from any modern CDROM drive.
You don't need to set it to 512 byte mode as this is done by the systems'
firmware. If You open a Cxxx or Bxxx with CDROM You'll recognize that there
is no jumper set to switch to 512 byte mode.

I used several CDROMs (from old and new Toshiba, some Panasonic/Matsushita
drives, TEACs, NECs and others) on different Cxxx machines without any
problem. Of course it's possible that a certain CDROM model might refuse the
byte mode switch command but in generall the masses of SCSI drives works
just fine.
