Your problem with the G3 B&W OS install and update file corruption is
caused by the Rev. 1 logic board IDE controller. Your 120GB drive is
too large for the controller to handle, and even if you got it to
accept an OS install, it would corrupt the file structure very
quickly.
This problem is the major reason for the introduction of the Rev. 2
logic board.
You have three choices: Run with a 20GB or smaller drive, Upgrade the
logic board to a Rev. 2, or purchase a third party PCI ATA100 or
ATA133
IDE controller card.
20GB drives must be tested because some manufacturers/models will not
run without corruption on the Rev. 1 logic board controller. This is a
tedious method for finding a compatibile drive.
IF you can find a Rev. 2 logic board for $60-$110, this will fix your
problem since Rev. 2 logic boards have an improved IDE controller that
does not have the corruption problem. However, you will be limited to
drives smaller than 128GB.
The PCI ATA IDE controller cards from Acard AEC-6280M and
AEC-6885M, as
well as the Sonnet Tempo are reasonably priced, and will also allow
you
to run hard drives larger than 128GB. They have two channels, with two
drives per channel capability. These cards cost from $55-$85, and are
readily available from OWC, Newegg or the manufacturers.
If you decide to buy a third party controller (the easiest, cheapest
and best solution), you can also get a PCI SATA/150 controller from
the
same manufacturers which would allow you to run SATA drives as well.
You would, of course, have to buy SATA drives.
Anyway, sorry for the bad news re G3 B&W Rev. 1 logic boards, but at
least you now know there is a more than acceptable workaround. The PCI
ATA133 controllers and PCI SATA controllers are both twice as fast
than
the built-in logic board IDE controller.
Ross is dead on target here. I have a Rev. 1 and a Rev. 2 B&W and I
had fits with the Rev. 1. Loading even Jaguar was problematic.
Crashes (excuse me, "Kernel Panics") were common, and this is despite
the fact that I had a Sonnet 133 ATA/PCI controller card. The
culprit? My $25 per stick memory from OWC (which, BTW, runs fine in
my Rev. 2). I replaced these with "more friendly" RAM, loaded Tiger
and I am one happy camper. OWC admits that the RAM is incompatible
with 'some versions of the B&W G3.' Get the ATA or SATA controller
and good RAM, and your troubles should disappear. My two cents
worth. . .
