can I port an iBook G4 install to an iBook G3?

[foothead]

I just bought a parts ibook from ebay, but I managed to fix it, except there was no hard drive. I currently have a 6 GB HD in it with OS X.3.9 on it, but I want tiger. I have the tiger family pack, so I have a license for it. It only has a CD-ROM drive, so I am wondering if I can buy a 40 GB HD, and clone the one from my G4 onto it.
SPECS
:apple: ibook G3- 500 MHZ
192 MB RAM
CD-ROM
currently has 6 GB HD
:apple: ibook G4- 1064 MHZ
1.25 GB RAM
Combo drive
40 GB HD

thank you for your help.

You could put the G3 into target disc mode (Hold down T while booting it) and run the tiger disc on the G4 and choose the G3's hard drive to install it on. It should work.
