Lombard firmware?

Hello all. I have a G3 PowerBook Lombard. It was a 333 MHz ** I replaced it with the 400 MHz processor and increased the ram up to 256mb and it's running OS 9.2.2. I'm going to replace the 4 GB HD with a larger one so that I can upgrade to OS 10.3.9. What I want to know if there is a Boot ROM version (aka firmware?)that I need to upgrade to and install. The current version is 1.0f1. Some might wonder why I'm doing this but I got this computer for free and I soon found out it works just fine. I have a Pismo 400 MHz (also got it for free)and I upgraded it to OS 10.3.9 and it too works fine. The version on the Pismo is 3.2.7f2. Could the Pismo's version be what should be installed on the Lombard? Any help will be greatly appreciated. John
