Greeting:
A friend of mine has a 466mhz Powerlogix Wallstreet processor, but he cannot properly identify what series of WS machine it came out of.
Is that important to know? I had heard that they're two different processors for the two series. I tried looking up the info online but cannot seem to find much...
It shouldn't be a big deal. The CPU card has an EEPROM with the Mac OS ROM in it - the ROM is different depending on which generation of Wallstreet you've got. Fortunately, that doesn't matter to you.
Before you install the upgrade, run the PowerLogix utility on the CD that came with the upgrade (it did come with the upgrade, didn't it? If not, email me privately and I'll hook you up with it). The utility copies the Mac OS ROM from your original CPU daughter card to your hard drive, then tweaks the OpenFirmware somehow (probably installs an OF script or something). Anyway, after you've done that, install the upgrade. When you boot the Wallstreet, the upgrade will see that there's a copy of the Mac OS ROM on the hard drive for it to copy into it's EEPROM. It updates it's flashable ROM with the new copy of the Mac OS ROM, then continues to boot.
MAKE SURE YOU KEEP THE ORIGINAL CPU in case you ever have trouble with the upgrade. You'll need it for some troubleshooting.
PowerLogix shows a nice little video of the firmware doing it's thing on the CD-ROM. My WS didn't do that when I upgraded w/ a 466MHz CPU - the screen stayed blank for a while (a little longer than it normally does after a cold boot), then it booted right up. I've since had some difficulty, though, and the PowerBook doesn't boot at the moment (worked great for about a month). I've heard that sometimes the image in the EEPROM can become corrupt, so I'll try fixing that first... But that's kind of a pain as it involves swapping CPUs, etc.
Peace, Drew
