The choice of old OS X system is the bottleneck in the process.
Little or nothing is available for OS X 10.1.x. In fact, it is getting
harder to find web browsers and applications to run in 10.3.9;
and that is only three systems back from the current 10.6.x.
The system in your computer is too old for the series of browser
and the adobe flash player plugin; and for most OS X use past
that antique 10.1.x system, you would need all the RAM that
computer can support to be installed. The "System Profiler"
should be available, from the main menu bar, below the Apple
icon, perhaps in a second button from "about this Mac." That
should be able to tell you the processor, hard drive size, etc.
And if the internal hard disk drive is not very large, that may also
need to be replaced with a larger capacity drive. If your iBook G3
is a white plastic model with a 500MHz processor or larger, the
possibilities of what OS could be installed will be limited by the
RAM available, hard disk drive capacity, type of optical drive
since later OS X versions shipped on DVD while older Macs did
not usually have a DVD drive. And then, graphics processor or
VRAM, bus speeds and processor speeds rule out later OS X.
You may be able to install Tiger 10.4.11 if the computer has an
optical drive capable of supporting DVD media; or if you have
a second computer with that drive and then use FireWire cable
and Target Disk Mode, you could get past the media type issue.
Few Tiger installer CD disc sets were available; so that may be
an issue for older computers without a built-in DVD drive.
Downloads for later OS X-intended systems should not be able
to install; and to be sure about what may, you would have to read
in the support pages for documentation on what kinds of systems
and associated hardware the software was intended to run on.
{You can look up your computer and see where it stands among
others, newer and older, with a nice free download database from
http://mactracker.ca if you have a computer new enough to see it.}
The computer sounds like a good one to run OS 9.2.2 on.
Good luck & happy computing! 🙂
