Blessing A Mac OS 9 System folder in Jaguar.

I have my old iMac G3 upgraded to Jaguar successfully, but OS 9 was still on my old HD, so I copied it to my USB flash drive and Pasted it into my Jaguar HD (in a partition called Macintosh HD).
Still, my iMac won't boot into OS 9 or recognise it as a Classic System folder.
I found out on the web that the system folder needs to be "Blessed" by the terminal.
I don't really understand this, so can anybody give me a terminal code that I can paste it into the Terminal.

Additional Details (if you need it):
1.My HD is divided into 2 partitions, which are "Mac OS X" and "Macintosh HD"
2.The Mac OS 9 system folder is copied into the partition "Macintosh HD"
3.The Mac OS 9 system folder's name is "System Folder" which is in the root of the Partition "Macintosh HD"

iMac G3 233 MHz, Windows XP Pro

A few things to consider.

If the flash drive is formatted for Windows (FAT32 or NTFS), it may be readable and writable with Mac OS X, but if you copy Mac OS 9 files to it, the resource fork of the data may be lost (or not copied properly). So if this is the case, I would reformat the flash drive using Disk Utility on a Mac to +Mac OS Extended (Journaled)+ and copy the System Folder again.

If the iMac G3 is a 233 MHz model (a tray-loader), and the hard drive has been upgraded to larger than 8GB, the system files (whether it is Mac OS 9 or Mac OS X) must entirely reside within the first 8GB of drive space. This is because the IDE interface can only see the first 8GB of drive space during startup, before the full OS takes over. Therefore, the drive must be partitioned so that the first partition is entirely under this 8GB limit, and the system files must be on that partition. 7.5GB is a good number to use. The other partition becomes usable once the full OS takes over, up to 128GB total for all partitions. This limitation affects direct booting, but does not affect the use of a Mac OS 9 System Folder for Classic under Mac OS X.

As for blessing it, if you can select the Mac OS 9 System Folder in System Preferences +Startup Disk+ pane, select it there. Selecting it there should bless it.
