I think James is on the right track. Certainly OS 9.1 will work swimmingly on a PTP (or PowerTower or PowerCenter, etc.), and the error message you get smells of disk driver issues.
To review, Power Computing licensed the Mac OS and various components from Apple, but for whatever reason didn't license (or wasn't granted) the Apple CD-ROM and Hard Disk drivers, which worked only on certain "Apple-approved" drives. Power Computing instead shipped machines with OEM versions of FWB CD-ROM Toolkit and FWB Hard Disk Toolkit, which worked on most drives of the era. I've installed OS 9.1 on two new Seagate drives. In each instance, I used the Apple Disk Setup utility that came with OS 9.x to format the drives successfully. (I believe the version of Disk Setup that shipped with OS 9.x was more forgiving, or worked with more drives, than earlier versions.) It all worked swell. I also agree with James that your greatest likelihood of success will be to reformat the drive as he described. Obviously, back up all your data (documents, email data, browser favorites, etc.) first. Hopefully, you have the original install disks for all applications so you can install them fresh from CD or floppy or, in the case of free apps, can download them fresh. But to be safe, if you can, back up your entire drive to, say, an external hard drive. (Reformatting means data on the drive is gone. Forever. Nuff said.) If the Apple Drive Setup with OS 9 fails to format properly, you might consider Intech's hard disk utility. I bought the Intech CD-DVD SpeedTools driver, and have found it to be an excellent product that can recognize many more drives than even the current FWB CD Toolkit can (even rather obscure items like the MicroNet CD/archive box) and is a no-brainer to use. (Explicit directions: Install. Go on with your life. Smile.) Plus, Intech promises free upgrades for life (FWB doesn't). And I believe it's cheaper than FWB's products. See: http://www.speedtools.com/ (Disclaimer: Don't work for Intech, just a satisfied customer. If Intech were around back when Power Computer was, or if Power Computing had contracted with Intech instead of FWB, their machines would have been just about perfect!) Worry not. Your PTP will run OS 9.1 just fine. -- Chuck >> I am having serious problems running OS 9.1 or 9.2 on my Power Tower >> Pro 225.
