Disk utility's help file says make an ISO of a CD,
then mount the ISO and burn it to a blank CD.

Says nothing about bootability.

Result is not bootable--but I'm not sure whether
it's the CD or the drive.  Drive mounts and Finder
shows files, but it won't boot.

Tiger PPC.  Suggestions?

Well, there's more.  This CD will not boot on either
of two machines.  But both can mount it and the Open
Firmware as well as Startup Disk show it as options.

So it's obviously the CD, right?  *BUT* I dug out an
original retail 10.0.3 CD and it will mount on either
machine, and startup disk offers it as bootable.
But then it won't boot either--and the OF boot menu
does not even show it.

First of all, Tiger retail disks were DVD's. Tiger CD's were never sold, they
were only available if you bought a retail DVD and sent it in for exchange.
The price was a small shipping and handling fee, e.g. $10 in the US. The
exchange program was not available in all countries.

If you have an original Tiger CD, from the exchange program it would be
bootable as long as that Mac boots from CD (some older Macs which had their
Apple drives replaced with PC drives are not).

If it is a copy, it may have been coppied incorrectly. There was a version of
the Tiger CD's floating around the Internet that appeared to be correct, but
were unbootable.

The trick is that when you mount your original CD, diskcopy offers you
a choice of copying the disk or the volume. If you copy the disk, you
get a bootable copy. If you copy the volume, you don't.

Copying the disk with Toast or cdrdao (a command line utility, you have
to download) will produce a bootable copy.

If the original can not be booted, there is AFAIK no way to make bootable,
nor create a bootable CD from it. Theorecticaly you could create a bootable
CD image and copy the files to it, but I think it would be difficult to get
something that actually booted far enough to install it.

That's probably it.  So if I can't find the other, I have to pay Apple
$35 for a replacement.  Sigh.  On the other hand, original CDs for OS 9
and Panther won't boot either--on two machines.  Yet both machines can
mount the CDs.

Did those machines ship after the original CDs were released? That would
be one way to get that behavior.

I can mount an OS 8.1 CD on this MBP, but it won't in any way consider
booting the disk.

Well, the machine that's fully up is a 1 GHz G4 eMac, so probably yes on
that one.  But the one I want to rebuild is a 400 MHz iMac, so i think
it was built before I purchased 10.3 and the 9.2 that I tried.  The 10.3
disk 1 that I bought then is the one I can't find, and the ISO is the
10.4. for this eMac that didn't have its CD or DVD when I bought it.

I was hoping I could load 10.4 on a partition of that iMac and use that
to restore 10.3 from backup.  I did the restore by FireWire from this
eMac and blessed it, but it still won't boot.

I assume you mean your specific CD.

There was a bootable 9.2.1 CD in the box with Mac OS X 10.1, and it was
a generic disk supporting all models compatible with Mac OS X (prior to
that point in time).

All Macs sold after the release of Mac OS 9.2 included a bootable 9.2,
9.2.1 or 9.2.2 CD specific to that model, until Apple dropped support
for booting Mac OS 9 (about 2003, varies a little depending on the
model).

As for your various other CDs you've mentioned:

Retail 10.0.3 should be able to boot any 400 MHz iMac G3, but it won't
boot a 1 GHz eMac.

Retail 10.3 should be able to boot all iMac G3s, but for the eMac it
depends exactly which model you have. The USB 2.0 model came with Mac OS
X 10.3.3 and wouldn't be supported by retail 10.3.

Is your 10.3 a retail CD (black label) or model-specific (grey label)?

Is your iMac G3's firmware up to date? (The firmware update must be
installed using Mac OS 9.)

This one came in the retail box with 10.3--unless I somehow got the CDs
mixed up.

It is a 400 MHz iMac G3.  I bought it used after I had purchased 10.3
I don't remember what version it arrived with, but I know that I put
10.3.0 on it and then updated.

Ouch.  Info says it's PowerMac4,4 - 1 GHz G4 (3.3)  Oddly, there is no
version info on the USB controller.

> Is your 10.3 a retail CD (black label) or model-specific (grey label)?

It's blue and I purchased it as "10.3.2" but when it arrived from Apple,
the box said 10.3.2 but the CDs said 10.3.0

> Is your iMac G3's firmware up to date? (The firmware update must be

Yes - unless there's something newer than 4.1f9  I see the G4 has newer,
but I suppose that is not for the older machine.

Here's something interesting: The system profiler says "The startup
device has been selected, but .... unable to determine which ATA device
it is"  After the power loss, the 10.3.9 and 9 partitions had errors.
Disk Utility fixed OS 9 but couldn't fix Panther.  I reformatted Panther
with Disk Utility, and it no longer had errors.  I restored its contents
with rsync and blessed it (over FireWire) but it would not boot.

I have done that sort of restore before and had it remain bootable, but:
 - it was via Ethernet and NFS, not FireWire and TDM.
 - it was the rsync that came with RsyncX (-eahfs) and not the one
   that came with Tiger (-E)
 - the 'bless' was the Panther version before.

I cannot find the 10.3 retail CD, but I thought maybe I could bless
the folder by booting the 10.0.3 CD - it won't boot, nor will the 9.2
that came with 10.3 (I moved the CDs from the box into two double hard
cases which until recently were stacked on top of each other.  Someone
for unknown reasons has moved disks one and two, leaving only disk three
and the OS 9 disk.)

I've been checking eBay and have been outbid twice on "sealed retail
CDs original box."  I'm hesitant to bid on others not only on the
legal issue but also concerned about scratches.

In desperation, I downloaded ISOs that allegedly were for bootable
Tiger retail install.  That would be ethical (in my opinion) for backup
of this eMac that sold with Tiger, and while not licensed for the other,
I figured that if I could install a bootable Tiger on the G3, then I'd
be able to restore the legal Panther that it was running before.

I have a 10.3(.0) retail box. It didn't include Mac OS 9, but mine is
second hand so it might have been mislaid by the original owner. The
content label on the box only mentions Mac OS X and Xcode, so I'm pretty
sure there was no Mac OS 9 CD in the box. (If there was, it would have
been 9.2.2.)

I also have a 10.1 retail box. It did include Mac OS 9.2.1 and the box
says so.

I don't have a retail 10.2, but I remember discussions at the time of
its release that it no longer included a Mac OS 9 CD.

PowerMac4,4 is one of the first three eMac generations, with USB 1.1.
The first two predate the release of 10.3, and the third one came out
the same month as 10.3 so I expect all of them will work with a retail
10.3 CD. The 3rd gen might have issues if Apple included a custom 10.3
build with that model rather than supporting it in the retail build.

1 GHz means you have the 2nd or 3rd gen. There is no easy way to
distinguish them, except that the cheaper 3rd gen had a combo drive. If
you have a superdrive it could be either generation.

Some late sales of the 2nd gen (in October 2003) included 10.3
preinstalled.

The serial number could narrow it down. The third character is the last
digit of the year of manufacture (3 or 4) and the next two are the week
of manufacture. If those digits are 344 or higher then it is definitely
a 3rd gen (manufactured in Nov 2003 or later), and I expect Apple was
making them at least a month or two earlier, so 336 or higher is
probably a 3rd gen.

The retail product codes also differ: M8590LL/A is the 1 GHz 2nd gen
eMac, M8591LL/A is one of the 3rd gen models. This should be on the box
if you still have it.

I've never seen blue Mac OS X CDs, at least not genuine Apple ones.

Agreed - 4.1.9 is the latest firmware for all 400 MHz iMac G3s.

I can't think why your 9.2, 10.0.3 and 10.3 won't boot on that computer,
as long as they are retail versions.

I wonder if file ownership might have been a factor. If you have an
external disk mounted with "ignore ownership" selected in the Finder Get
Info window on the volume, every file on the volume appears to be owned
by the current user. This might prevent restoration or blessing of a
viable system.

OK, I must be mixing things up.  I got out my box and it says the same
thing.  But the CDs aren't in there.  I transferred them to two
double-CD hard cases, the first of which has walked away.  And they
(like the carton they came in) are black.  Well, at least disk three is.

eMac shipping box?  I bought this used, repacked by the store that
had gotten it from a school.

You're right.  10.1 is the blue one.  The other is white with an orange
nine, and it is 9.2.1, not 9.2.2  I thought I had a 9.2.2 CD, but maybe not.

> I can't think why your 9.2, 10.0.3 and 10.3 won't boot on that computer,

Sigh, again I am mixed up.  I grabbed the 10.1 _upgrade_ instead of the
10.0.3 full retail.  and the 9.2.1 is an update, not a bootable retail.
I don't have the 10.3 disks one & two.  They're in the case that walked
away.  What won't boot is the 10.3.9 that I restored from backup by
FireWire.  The others were an attempt to load something bootable on it
that I could then use to restore 10.3.9 with.

Not much difference anyway.

Ah, white with a blue X or orange 9 - I thought you meant the CD label

Hate it when that happens. I just found mine (they weren't in the box,
but were in the drawer along with my other system CDs/DVDs).

Is that because they intended for it not to work on future machines,
or because the CDs were designed with specific drivers for all known

Changing the subject: I also have a Sun to upgrade.
I downloaded the bootable ISO from Sun.

Mounted it with disk utility which made two items appear.
I assume the upper one is "the disk" and the lower
indented on is "the volume"

I selected the upper one and clicked 'burn'

Machine burned and verified.

Ejected, and put in Sun.  It will not boot.

I know this is going to sound stupid, but did you download the correct
architecture? Solaris is available in x86 (Intel processors) and SPARC
versions.

To be honest, I've never used an Intel based Sun, although I have run
x86 solaris, so I can't answer that. SPARC machines won't boot from a
CD unless you hit stop A when they start up (SUN logo on the screen) and type
"boot cdrom".

I could write a full page (and have, so I won't repeat it here) about booting
SUN computers from CDROMS, but that should be enough to start. If it isn't,
contact me off line.

Yes.  Took me two days to get it--I kept getting x86 and was getting
rather confused because I was sure I was going for SPARC.  Apparently
something on Sun's site was broken, because as far as I can tell,
I did the same thing today that I did the other two days.  I also
downloaded the x86 and installed it in VMWare at work.

Anyway, it's the right one.  After having the same problem with
the Mac CDs, I used an RW for this one.  :-)

Yeah, I worked mainly on SPARC for over a decade.  But this is the first
time since 2003.

Well, since you mention it, do you know what keyboard shortcuts
there are?  I have to do this without a mouse.  :-)
