Can't open CDs in Open Firmware

Question

Can't open CDs in Open Firmware

I'm working on a dual boot setup for my laptop, and I have run into an interesting problem: I cannot boot from CDs. If I boot into Open Firmware, and try booting the CD from there, it says that it can't. Entering dir cd:\ in the OF prompt tells me that it can't open cd. Which leads me to believe that there may be a driver problem. I can boot the OS X Leopard DVD fine though. At any rate, it would be nice to know if it's possible to get new drivers, or if there is any way around this. Thanks.

Tibook 867mhz, Mac OS X (10.5.5)

I think the dir command is expecting a HFS or HFS+ formatted volume. What format is your CD?

The CD is HFS formatted, and my hard drive is HFS+

OK. I don't think I can help you more: that's about the limit of my knowledge of OF 😟

Why is there a colon in that cd command? Is this some PC thing?
And why "dir" and not "ls"?? And what's with the backwards slash?

If cd is a directory the command would be ls /cd or something like that.
What does the command ls show is in the directory? Is cd even a directory?
Usually cds are usually mounted in /dev under disk. I have never seen a cd mountpoint labeled cd.
cd seems to be a very confusing name since it's also a command.

Open Firmware is not a Unix shell.

That's good to know. I guess it's Forth, then.
