Upgrading iMac 233 hard drive

[hulugu]

I'm upgrading my iMac (running 10.3) to sell to a friend, and after replacing the original 4 GB harddrive with a 13 GB IBM I had sitting around the machine refuses to boot from the hard-drive. So, I tried another drive, and alas got the same result. So, I dropped the original HD and the iMac boots fine.
What can I do to get a newer, larger capacity drive to work with this iMac?

Any ideas would be appreciated.

You need to partition it so that the boot partition is less than 8G. It also has to be at the start of the drive.

If its not this then you probably have configured the jumpers wrongly.
