I've just downloaded and burned the ISO's for YDL 4 on my Powerbook G4. I can mount and boot from them fine on that machine, but the disk won't boot or mount on either my B&W 300 or my iMac DV 400. I made 2 disks using both Disk Utility and Toast and neither work on the older hardware...

Any ideas? From what I can tell they are both new-world machines and should boot with the yaboot...

thanks,

The fact that they won't mount implies that the CD drives in the older machines may not be able to read the CDRs that you used. I suspect if you burned a normal data disc on the same CDRs, they wouldn't be readable either.

no, those drives read regular mac formatted CD-R's fine, burned from the same PowerBook. Same brand of disk in fact. This is a problem with the YDL format as far as I can tell.

You also didn't specify what OS the other machines are running. There is nothing about a specific file format that would make one model of machine able to read it and another not. If the different machines are running the exact same OS with the same file system drivers, then they should be able to read it (especially since you said the brand of CDs works otherwise). Booting may be different, as that's dependent on the machines ROM. The only example I can think of with file system type making a difference is with HFS vs. HFS+. 68k machines can't boot from HFS+.

That is the weird thing, all machines are running 10.3.7, and only the PB will mount or boot the disks.

btw, booting off the ydl disks on the PB mangled my user permissions. Made all user files read/writable for all users... Even though the permissions were clearly not set that way.
