I can also assure that taking any such original discs, using Disk Utility on early OS X (10.4, for example) with period hardware (in this case, a G4 tower), selecting the entire disc from the list (not just the volume), and creating a CD/DVD Master image (equivalent to an ISO) will yield a perfectly good burned copy to start a machine from. I have done it over and over and it works without fail. That's an alternative to Windows or OS 9 if that is what you have to work with.Okay, in the interest of satisfying my curiosity regarding this particular ISO file, I’ve decided to burn several copies using different OS and burning tools.
I’ll update in a little bit once I’ve compiled all of the results and screenshots.
Yes, I agree, IF DONE CORRECTLY by selecting the top device and making an image from the drive device instead of just the mounted volume, you can also image the file so that it contains all of the bits properly.I can also assure that taking any such original discs, using Disk Utility on early OS X (10.4, for example) with period hardware (in this case, a G4 tower), selecting the entire disc from the list (not just the volume), and creating a CD/DVD Master image (equivalent to an ISO) will yield a perfectly good burned copy to start a machine from.

Geez people, one night can make a differnece!
It would be very nie if you could provide me with this OS. English is fine.
Press X to doubt. Because the OS 7.6.1 from macos9lives works perfectly. Only one attempt. BUT I guess this image was made on a real old PPC machine using toast with the bootable checkbox checked. It was also wrapped in a .bin archive. And I don't even know if ,bin is still a thing in MacOS X.
Was this a G3 or after? Performas (PPC603e) is a different architecture and more or less different processor
Yes. But this was a problem with very old amchines. and 700 MB only means that the CD-R CAN handle 700MB. If you burn e.G. 200 MB on it no problem. That is why you never make a 650 MB iamge for 200MB of date especially if it is a system or a bootable system. This is going to fail on old machines. It won't fail on G3 and after machines.
-------------------
My guess is the following: people have made copies of the maybe even original CDs with macos X or even in the classic environment in Mac OS X but never checked the "bootable" checkbox in Toast. I know that, becasue I had the same problem back in the late 90s when I was surprised that OS CDs I made weren't bootable on my friends Max.
In the "old days" you could just make a copy of the system folder, place the system folder on the new harddrive, drop the finder and I think it was the system file on the dektop (that gave the 2 files the "bless" bit"), move these 2 files back into the system folder and bang: you had a bootable drive. Pre-OS X is VERY different from MacOS X.
Thanks @Juror22A big shout out to Moloko for starting this thread. I'm giddy that I was able to get a peek into a corner of MrFahrenheit's 'bat cave' and get a look at some of the drives in action, as well as the stacks of media, which were on hand.
I also have an A&W glass on my desk, but instead of refreshments, mine holds tools, Xacto knives, that sort of thing, although I do like to occasionally throw one of my other mugs in the freezer and have a frosty one too.
A .bin is used to protect the resource fork. An ISO isn't a macintosh specific file format.Hi,
so....
NOPE
And I also tested on my Umax J700 and S900 (G4).
Boot start, happy mac, stop (exactly the same).
I also changed the burning process:
I used my old Yamaha 2100IX connected via firewire to my MacMini 6,1 running 10.9.5 using burn 3.16 and burned the CD with 1x Speed as a copy of the original ISO image
Now:
why does the 7.6.1 and the 8.1 from macos9lives work. I guess because they are both wrapped in a .bin archive
MacBinary - Wikipedia
en.wikipedia.org
„....MacBinary is a file format that combines the two forks of a classic Mac OS file into a single file, along with HFS's extended metadata. The resulting file is suitable for transmission over FTP, the World Wide Web, and electronic mail....“
I am totally willing to test this again but have to wait until my new CD-Rs arrive.
I really appreciate all of the effort from you guys.
Because if the problem is just the wrapping and we can’t get the uploaders of these system discs to wrap them in .bin, in 10 years from now we might have lost 20-30 years of technology.
Because right now it would be easy to fix.
No, as Phipli is rightly pointing out, a .bin wouldn't make any difference with a .iso file because there is no resource fork to protect.why does the 7.6.1 and the 8.1 from macos9lives work. I guess because they are both wrapped in a .bin archive
@Moloko if you do this, carefully follow @MrFahrenheit's instructions for making an image, otherwise @robin-fo won't know if specific issues are because of how your burnt the disk, or how you made the iso / toast image.Maybe it would be interesting if you could create an image of your unsuccessfully burned CDs for us to analyze?
Which image? You need to be specific.if I burn the .iso image
