In my opinion a fresh install includes formatting your hard drive. It didn't work and diskutil list showed it as "Unknown. If your backup is ready now is the time to figure out how you should install macOS fresh. I also tried dd-ing a working SheepShaver boot image to the physical disk, but I guess that doesn't have a partition map on it or something. If I hold Option I get the Reload and Next buttons but no disks are shown. But when I boot the PowerBook with the drive hooked up I just get the blinking folder icon. Then I formatted the physical drive with an Apple Partition Map and the partition as HFS Extended Journaled, then I mounted the drive and copied (dragged over) the files and System Folder from the newly-installed disk image. I tried creating a new 512 MB disk from SheepShaver and running the Mac OS 9.2 Universal Installer to install OS9 on it. SheepShaver cannot use physical media, so I cannot connect the disk to SheepShaver and run the Mac OS 9 installer on it.It has a 20 GB 2.5" IDE drive and I have a USB to IDE adapter, so I can connect the drive to the MacBook with Mac OS X.The PowerBook originally had Linux or BSD on it or something, so a full reformat is needed.I tried using BootMania but it won't let me create an image from any of the Mac OS 9 install disk images I have. It has Ethernet, and I have a recent MacBook with an Ethernet dongle, but everything I've read about NetBooting and NetInstalling seems difficult and unapproachable. A clean installation of macOS Big Sur basically means the entire hard drive including the system itself, all data, all apps, user accounts, literally everything is erased, and then a fresh clean install of macOS Big Sur is installed onto the Mac.Apparently the PowerBook G3 Pismo and Lombard variants cannot boot from a USB stick.The PowerBook doesn't have a CD-ROM, just a plastic spacer.There are games that simply don't perform well with SheepShaver, plus networking with SheepShaver isn't reliable with Classic multiplayer games. I have a PowerBook G3 from 2000 or so and would like to put Mac OS 9 on it for nostalgia reasons.
