Install 9.03 on a Japanese iMac G3 with 8.5

[KCM]

Hello, I'm new here.
I bought an old iMac G3 at a recycle shop in Japan just because I like the design.
I'm new to apple but I would like to make it work with an English OS that I found, and also to get to understand Apple.
9.0.3 (on disk, for DV Models).
Erased the Japanese OS (8.5)and when click install the 9.0.3, a message comes up; " your Mac's firmware is out of date. updates can be found in the CD Extras folder on your Mac OS CD".
maybe I'm stupid but I can't seem to find it on the OS CD in Extras Folder at all.
Please somebody give me advice.

BTW. I went to Best Denki today to look at the new iBook 13.1 inc, it's a beauty but expensive, Jap Yen 114.800. But the salesman showed me that it is BILINGUAL. maybe this will be my first laptop afterall.

But first I would like to find uot more about Apple.

Thanks.

Mr. Super Moderator, not everybody is as intelligant as you.
Some of us are just beginners.
if you have no patience you should take a sample at my japanese salesman I've met today.
