Updating imac g3

Mac OS X must be installed on an IDE drive smaller than 8 GB or on the first partition of an IDE drive larger than 8 GB - and that partition must be smaller than 8 GB.(Mac OS 9 needn't be on the first partition, but it must be within the first 8 GB of drive space.) Because a gigabyte is sometimes one billion bytes and sometimes 2^30 bytes (that's 1,073,741,824 for the binary challenged), we've recommended that the partition be no larger than 7.45 GB to play it safe.One of Bill's tricks is to do the entire Mac OS installation in another computer, one that supports two internal hard drives.You can use a Blue & White Power Mac G3 or any Power Mac G4, as the drop down door makes access to drives fast and easy.Here are the steps: Another option is to use an external Fire Wire enclosure for formatting/partitioning the receiver drive and cloning your disk image to it.Using this process, you can create a bootable OS X drive for a tray-loading i Mac, beige G3, or Wall Street Power Book without ever touching XPost Facto.What Bill likes to do is scrounge up smaller, generally faster replacement hard drives, usually in the 10-15 GB range, and put those in the old tray-loading i Macs.One issue the tray-loading i Macs, beige G3 Power Macs, Wall Street Power Books, and Clamshell i Books share is a transitional hardware architecture that runs into problems with IDE/Ultra ATA drives on the built-in drive bus under Mac OS 9 and OS X.

Hard drives that may not be big enough for Mac OS X 10.4 "Tiger".

(You can't boot from a CD to do a firmware update; you have to boot from a hard drive.) Be sure the firmware update has taken before upgrading your Mac OS installation, as you can otherwise end up with a Mac that won't boot with the OS you've just installed.

Another tip from Bill: If you do end up with an unbootable tray-loading i Mac and have access to another i Mac that's working just fine with the version of the Mac OS you installed, swap out the little daughtercard CPU modules.

Bill has found that our number is too high: Partitioning at 7.45 GB or even 7.38 GB results in unbootable OS X installations.

I've found the same thing when working with a Beige G3.
