I am a little confused on what I should be doing to upgrade my PTP225 to OS
9.1. I have the grey CD and a newly formatted hard disk (2.0GB). I tried
putting the CD in the CD-ROM drive and holding the C key to bot from the CD.
Nothing happened. I was able to reboot to the current OS7.5.3.

First, is the 'grey CD' from an iMac or other Mac install packet ? If so, there may be other issues such as the installer looking for machine ID, which will require other setup.

Second, if you booted from 7.5.3 on the same 2G HD you formatted, and that system sees the CD, you should have the option of a 'clean install', or installing OS9 over the existing system, while that system has control. Doing a clean install is preferable, although it means you'll have to manually transfer certain data such as the FWB CD-ROM Toolkit from OS 7.5 to OS 9.

Third, if you have a second HD available with a bootable system that runs the CDROM, boot from that system, install to the fresh 2G HD, and then manually transfer over the CDROM drivers to the new HD.

Fourth, if the OS 9 installer CD shows up when booted in 7.5.3, using the standard Apple CDROM driver, it won't require the third-party FWB drivers, as it has been replaced by a unit with Apple ROM built in.
Let us know which CDROM (brand & model) you have, if possible. PowerComputing used Teac 516s units in the high end models (16x read), and these require third party drivers.

ps...if you've figured out how to find this PowerComputing list you can't be all that dumb. Sometimes when I see the old timers here explain some obscure and complicated
routine, or correct some errant advice I've offered, I feel pretty dumb myself...=)



Do I need to prepare the CD and HD with third party drivers before I use the
OS9.1 disk? I've read your note below a couple of times and am still
confused. Can you help me by pointing out the steps to take to upgrade to
OS9.1 with this hardware. I'd like to try the software solution first.

Thanks for the help and sorry for being so dumb <g>.

One thing to bear in mind when using the PTP, or and PowerComputing unit,
is 
 that the CDROM, and in many cases the Hard Drive will require third party
 drivers, and they do not have Apple ROM built in as do native Macs. The
setup 
 disks which came with the units new had FWB CDROM Toolkit and HD Toolkit
 included, but are pretty rare these days. The are two solutions, software
& 
 hardware.
 The software solution requires either obtaining a copy of the toolkits,
hacking
Mac OS drivers or finding a copy of Mac OS 7.6 (the drivers for this
system 
 seem to work with many more strains of CDROMs)
 The hardware solution is to install a CDROM and hard drive from later
model
Macs which have a SCSI interface . These are readily available and cheap
either
in used computer/consignment shops, on eBay, and through LEM sponsors. The
PTP 
 will easily accept a second CDR as well, plus a ZIP drive if required.

I use one daily with an XLR8 G4/375 mounted on a ZIF card and running
MacOS
8.6. The PowerTowerPro is an excellent machine...the best of the Mac clone
era.
