This document lists the iBook firewire as having the 8 GB limit but I
know that the 366 & 466 SE (special edition) firewire iBooks do not
have the 8 GB limit, so it must just be earlier firewire iBooks.
Also, XPostFacto 4 (XPF) now works for new world Macs which means
that you can use any 1st 8GB partition or drive as a 'helper' to
enable the boot of a larger partition or drive that would normally
not be bootable. For example, let's say you had the firewire iBook
that had the 8 GB limit and you upgraded to a 60 GB HD. Any partition
within the first 8 GB could be used as a 'helper', but in this case
let's say you want to get the most out of the 8 GB. A good way might
be to partition the drive into 4 partitions total. Within the first 8
GB make two 1 GB partitions and a 6 GB partition, and then have the
remaining 50 GB outside the first 8 GB.
You can then install OS 9 onto one of the 1 GB to use as Classic, and
leave the other 1 GB empty to either use as a scratch disk or swap
volume. On the 6 GB install a minimal OS X to use as a 'repair'
volume so that you can run OS X Disk Utilities without needing CD's.
If you've installed Panther or Tiger you can then use Disk Utilities
Restore function to copy the clean installation from the 6 GB
partition over to the 50 GB (normally the OS X installer wouldn't
allow this since it's beyond the 1st 8 GB). You can also use
XPostFacto 4 to install from the CD to an "illegal" beyond first 8 GB
partition if you decided not to have a 2nd OS X partition.
Minimally you must have at least an OS 9 or OS X bootable partition
within the 1st 8 GB to initially boot from and run XPF from to get it
to boot the larger partition. What the 'helper' drive boot process
does is to copy BootX and Extensions over to the 'helper' and then
the boot synchronized so that it can be 'handed off' to the larger
partition after starting on the smaller 'helper'. The files that are
copied onto the helper are usually less than 5 MB, so even a single 1
GB partition with OS 9 can be used to launch XPF and boot the larger
partition (XPF is carbon, it runs in both OS 9 & OS X).
To boot the large partition you simply boot a smaller partition
(either 9 or X) and then run XPF and select a smaller 1st 8 GB
partition as the 'helper' and the larger as the boot volume and press
Restart (in XPF).
Being able to boot larger partitions is very helpful. You can also
boot Firewire on these new world (and old world) Macs whose firmware
doesn't normally support Firewire booting using the same helper drive
process.
