The specification iBook G3 (dual-usb) PowerBook4.1 covers two build series
of the portable; neither one shipped with Tiger 10.4.11 as it had not been
created yet; Tiger (OS X 10.4) was the last OS X it could run.
Tiger was available in limited quantities in a 4CD set; primarily it was on DVD.
So as Dual-USB iBook G3 had a Combo optical drive, it could see & use DVD.
A retail Tiger OS X 10.4 full install DVD would be the path to install an OS.
Or an earlier Panther OS X 10.3 retail install DVD, could work. Tiger is better.
Tiger is getting harder to find, and a grey-color disc from another computer model
would not work, usually. On rare occasion one may install, but more likely it won't
include the correct hardware drivers for the early iBook G3 white.
The 'model number' you show does not appear to match any model identifiers;
but does come close to the Battery model range. The Sales Model number is
more widely known, but I can't match yours that way; if you had a serial number
(it likely is on the case, or perhaps in the battery compartment) you could run
the serial number in the Lookup site (link) I posted before. I have the database
here offline, to see the specs on both the first Dual-USB (May2001-Oct2001)
as well as second Dual-USB build run (Oct2001-May2002) open on desktop.
1st Dual-USB:
| Introduced | May 2001 |
| Discontinued | October 2001 |
| Model Identifier | PowerBook4,1 |
| Model Number | -- |
| Order Number | M7698LL/A (CD-ROM), M7692LL/A (DVD), M8520LL/A (Combo) |
| Built-in Memory | 64 or 128 MB |
| Maximum Memory | 576 or 640 MB |
| Memory Slots | 1 - PC-100 3.3V 144-pin SO-DIMM |
If yours is the first-model Dual-USB, May/Oct2001, the chip RAM could be
upgraded to (between 576MB or 640MB total) depending on which build it is.
Some shipped with more RAM fixed on the logic board, while the upgrade
slot would take the same piece of RAM to make up the total. While the second
Dual-USB model, Oct'01/May'02, could use up to 640MB RAM total, but had
only 128MB soldered on the logicboard. So hopefully your iBook already has
the 1- PC-100 3.3v 144-pin SO-DIMM RAM installed, or it won't boot Tiger.
2nd Dual-USB:
| ntroduced | October 2001 |
| Discontinued | May 2002 |
| Model Identifier | PowerBook4,1 |
| Model Number | -- |
| Order Number | M8597LL/C (500 MHz), M8599LL/C (600 MHz) |
| Built-in Memory | 128 MB |
| Maximum Memory | 640 MB |
| Memory Slots | 1 - PC-100 3.3V 144-pin SO-DIMM |
These early models shipped with a pre-OS X system 9.1; later w/ an early OS X.
They were intended to boot into OS 9.1, & OS X; it shipped with complementary
set of fairly good software originally; but yours has none of that included.
{I used to own a first-model Dual USB iBook G3, 12", with wi-fi, 56k modem,
576MB RAM, combo drive, yo-yo charger, original box, and a pile of discs.
It was great fun, and I used it mostly with Mac OS 9.2.2, since it worked well
and earlier OS X at the time was not a good option with the 500MHz. When
I finally sold it to an 85 y/o guy down the road, it had Panther 10.3.9, too.
It was his first computer, and I helped him somewhat remotely by phone/email
to make fair use of it over several years time.}
As a matter of experiment, you could see if your later Mac's Disk Utility could
see those .dmg files, and somehow restore them to a DVD. Not a dual-layer,
and if they are really for the early iBook G3 dual-usb, they'd all have to be
on one DVD as a single resulting file; it would have to boot up the iBook. So
that means the resulting DVD also has to be read by the iBook optical drive.
There are so many if's just to see if those .dmg files could be used at all.
With a second Mac, with FireWire400 cable, you could try & see if you could
get this early iBook to start in Target Disk Mode, and see if the hard disk drive
has HFS or HFS+ formatting, and an Apple Partition Map, on that drive. The
iBook would appear as an external HDD to the other Mac, as by holding the
T key down on startup, that would make the iBook appear as a drive to another
Mac, attached by firewire cable. There is an article about this in Apple Support.

These other accounts of how to, are not something I can attest to or suggest:

Install OS X from dmg files:
http://www.tech-recipes.com/rx/2628/install_os_x_from_dmg_file/
These older OS X systems are too small to use a dual-layer DVD; though many
of the stories about the use of dmg files are from a later era, so they say you'd
need dual layer, that is not the case. Leopard 10.5 started a need for dual-layer.
But you may be able to experiment with those dmg files, and know they may fail
to be anything correct. The path to get a retail Tiger OS X 10.4 DVD is often a
matter of searching resellers online, such as amazon affiliates, or be very select
in reading ebay ads. People often get the wrong discs from resellers who are not
actual repair or restore companies, and are misguided by the sellers words. A
grey disc set from a computer kit, generally won't work with a different series;
and the build of the disc vintage has to match the year/model series Mac to work.
So, that is why a 'retail' install DVD is required, of a system newer than the one
the computer shipped with. And Tiger 10.4 is the best one for the early iBook.
That is because you could still get a web browser and a few good applications
if you look long and hard to find them, that run under Tiger 10.4.
The last step of Tiger 10.4 is a combo update file, a download from Apple that
should be available by running Software Update in the running Mac OS X. None
of the original system parts (Mac OS 9.1 or Mac OS X 10.1) would be available.
Anyway, I'd suggest looking into local used computer stores, thrift stores, or
school sales bins for old software discs; though those places are likely picked
over fairly good. A local Apple User group in your vicinity, may be a source of
ideas and maybe someone has original or retail DVD system, they'd part with
for a reasonable cost. A few independent Apple specialists may know of other
Mac users who may have upgraded to newer stuff, yet hang onto older Macs
or their parts, software, etc. So these may be local places to attempt to get a
few leads. Companies such as welovemacs used to have software, but now
that is harder to get; and prices can be higher, too.
Perhaps someone will see your post and add ideas; certainly there are many
out there and I've ran out of time. And already think this is too wordy...
Good luck & happy computing! 🙂
