Reinstall Leopard on ibook G4

Does it boot to Single User Mode, CMD+s keys at bootup, if so try...

/sbin/fsck -fy

Repeat until it shows no errors fixed.

(Space between fsck AND -fy important).

A substitute link to one offered (docs.info.apple/com...) that while archived, still exists, is this:

Since the iBook G4 (14-inch) 1.42GHz (mid 2005?) has no 'clock battery' only a capacitor on

the logic board, the best hope is to get a good reputable battery (newertech/macsales/owc)

and be sure the unit is charged enough, long enough, for the capacitor to hold feeble charge.

If the Leopard 10.5 install-restore DVD media isn't an official retail version, none of the grey-

labelled disc sets would work; and none of the iLife or iWork, etc applications were included

on the retail Leopard OS X 10.5 install disc. There was an official bundled upgrade kit from

Apple which included the OS X, iLife, and iWorks; a rare find, sometimes on amazon stores.

Anyway I replied to your post so you'd note above link; & so the original topic could be filled

in a little more betterer. Hopefully you're doing OK and spring is arriving where you are. We

still have several feet of snow and near +12°F (no wind) at night. Partly sunny this week, tho.

Good luck & happy computing! 🙂

Assuming it's a Retil Leo Disc...

Leopard requirements/10.5.x...

* Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor

minimum system requirements

* 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)

* DVD drive for installation

* 9GB of available disk space (I say 30GB at least)

Classic/OS9 Apps no longer supported.

There are workarounds if the 867MHz CPU is the only hangup...

Other than a retail Leopard 10.5 install disc, the other official DVD that may be used if you can locate one:

"Mac OS X Leopard | CPU Drop-in DVD | version 10.5 | 2Z691-6040-A". -- This can be used to perform full

installation. Start up Mac from Installer. Run Disk Utilities, erase reformat hard drive, partition, & install OS X.

"This software is part of a hardware bundle - not to be sold separately. 2007 Apple"

I've one of these (also a few 'retail Leopard 10.5 install' DVD kits) and you need not have Tiger installed first.

This named install disc would have originally been placed in with a complete computer kit, or made available

to a 'fringe' new purchase owner of Mac which shipped with Tiger, to upgrade for free to Leopard 10.5.x.

Orphaned software packets from recycled or discarded Macs have some interesting things inside. You can

experiment with some, by using extraction utilities (so you don't need the official installers) such as Pacifist.

Anyway, hopefully you can get the correct media install disc set; helps to have about 30-40GB of HDD space

for Leopard; I've three different Macs with Leopard and the system likes RAM and virtual memory swap space

for temp files used as RAM (write/read to hard drive; dependent on rotational speed of HDD for performance.)

Tiger can run better on the original configuration; my iBook G4 12-inch 1.33GHz with 37GB HDD (stock) plus

1.5GB RAM has slow-RPM HDD. It could see significant performance gain with OWC Mercury Legacy SSD.

Good luck in any event...! 🙂
