hai! i've heard that you can "convert" the :
mac osx 10.1 update cd to an full install
cd!!! but i 've os 9.1. is there a way that i
can install os x full with only the update
cd?

1.Insert your MacOS X 10.1 Update CD
2.Fire up "Disk Copy" from /Applications/
Utilities
3.Select from the Menubar "Image | New
Image from Device..."
4.Select your CD-ROM drive's contents
from the resulting dialog
5.Image it as a "DVD/CD Master" type
(this will take a little while)

Modifying the CD contents
1.Control-click (or right-click) on the
resulting disk image
2.See that it's mounted
3.Navigate with the Finder to System/
Installation/Packages on mounted image
4.Select the "Essentials.pkg" file...
5....by right-clicking on it and select "Show
Package Contents"
6.In the pop-up Finder window, navigate
to Contents/Resources/
7.Drag "CheckForOSX" to the Trash and
close all these Finder windows

Burning your new Install CD
1.Go back to Disk Copy and select from
the Menubar "Image | New Image from
Device..."
2.Select the mounted volume you opened
up above and make another "DVD/CD
Master" image
3.Now select from the Menubar "Image |
Burn Image..."
4.Select your newly modified .dmg file
5.Burn it to CD and enjoy

It doesn't work from within OS 9. It only works if you already have OS X.
