No. Almost all early Unix cdrom drives did this because the system boot roms wered limited to dealing with 512 byte blocks. Sun, SGI, HP at least. So the vendors changed the cdroms rather than change the boot roms in the existing machines. Some early cdrom vendors conviently put jumper pads on the drive so you could fix it one way or another; later other vendors had code which tried to guess what the system wanted. To the vendors it was easier. In time, things became more adaptable. I am sure that google would have told you this same history.

Huh? CDROMs are just about the only devices out there that don't use 512. By default CDROMs use 2048 as the sector size. I can't say this for sure about these machines but I would be very surprised to see something like this. Is this a sun thing?

While this is true on sparc systems, I don't believe it is true on sparc64 machines. I recently tested booting off CD on a U1e with several off-the-shelf (i.e., not 512 byte sector, pulled from PCs) SCSI CDROM drives, and I am pleased to report they Just Worked. Nick.

also at the obp prompt run .version OpenBSD needs a minimum of the following version OBP_3.27.0,POST_1.1.1,OBDIAG_2.2 if your levels are below those you'll need to update the firmware http://sunsolve.sun.com/search/advsearch.do?collection=PATCH&type=collections&queryKey5=105930&toDocument=yes
Re: Openbsd 3.8, sun ultra 30, install problems
check the jumper settings on the CDROM, you need it set to 512byte sectors, other wise it wont work, if there are no jumper settings for it on the drive then its not compatible with your system. Sevan

Try that after reading the installation instructions and see if that works. It can be less hassle than hunting for the right cdr media. Noth

Actually, there are *many* older cdrom drives (computer and audio) that do not support (or do not *properly* support) CDR media. Sometimes CDR media works and sometimes it doesn't work. The main reason is the reflectance of most CDR media is far less than a "mastered" CDROM disc, older drives lack the power necessary to read properly from the less reflective CDR media. There is a work-around; Though it's tough to find, and expensive, there is a type of CDR blank called a "Diamond Disc" or "Diamond Media" -The "Diamond Media" has worked perfectly with every problematic drive I've tried including many drives that *officially* do not support CDR media (and even drives that predate the creation of CDR). I suggest trying to burn a knopix boot CDR and see what happens. If you can't boot from it. Try booting from a factory made Sun Solaris distribution disc. JCR

Sounds like a broken computer or a bad CDROM drive. Potentially, a bad CDR you made. I've also seen some machines that refuse to read certain brands of CDR media. Nick.
