Note that there is a big difference between the two. "boot cdrom" issues a
SCSI-II modes set command that allows many non Sun drives to boot properly,
"boot sd(....)" does not.

For "boot sd...) to work the drive must be set to 512 byte sectors. For
"boot cdrom" a standard Toshiba, most Plextors and Sony's and Apple CD-300
(Sony inside), but not the CD-300+ (Panasonic inside) drives will work without
changing jumpers, etc. AFIK NEC ones do not. 

Make sure the drive is set to SCSI ID 6.

You can get a "format.dat" file for SunOs with almost every drive made
and use it. However, it's a lot easier to do with Solaris. If you have 
a running SunOs system then the format.dat way is fine, but if you don't,
use Solaris.
