Will, I think that your terminology may not be accurate. My understanding is that Old World vs. New World has to do with where the MacOS ToolBox is stored and whether there is a rewriteable chip holding the Open Firmware. I could be wrong, in which case writing the following was an embarrasing waste of time. :-) But I think this is correct. So in an Old World Mac, the boot code, or Open Firmware on PCI macs, and the Mac ToolBox are both stored on an indelible ROM in the machine. On New World Macs the Open Firmware is on a rewritable Flash Memory and the Mac OS Toolbox is in a file which is loaded from disk. So, as you wrote, the iMac is the first New World machine. But the 6300/6400/6500 are old world machines. The Beige G3 is definitely an old world machine. Everything before the iMac is old world. I'm think the early B&W is old world because it uses the same type of ROM as the Beige, but somewhere in there with B&W and Yikes and all that, the transistion to New World was made. The group of machines you listed as the only Old World machines are the *PowerSurge* family of Old World Macs. Hence Umax's naming of the S900/J700 as Storm Surge. I think they are the only officially unsupported (under OSX) machines which Ryan has supported so far. He hasn't got the 7200 and Catalyst machines working has he? The PowerSurge family (in the form of the 9600 Enhanced) was originally supported by Apple under OSX Server (or a beta thereof) and I think that is what has made it much easier to support these machines under later OSX revisions. Is that correct? My memory is vague on how that worked out. Anyway, the PowerSurge family consists of the machines you listed plus the PowerWave and the Daystar Genesis. The 8600 and 9600 can kind of be listed twice as there were two different models of each of those. The defining characteristic of the PowerSurge family is the presence of the Hammerhead Memory Controller on the motherboard. None of the other chips on the board are really defining, because the Catalyst/7200, e.g., uses exactly the same PCI bus arrangement with a Bandit chip and the same interrupt handler (Grand Central) as the PowerSurge family. It just uses a different chip (Platinum?) for the memory controller. Going back to the original question, do the 6300/6400/6500 and C500/C600 machines even see their built-in IDE as IDE? Or do they identify it as SCSI? Jeff Walther -- SuperMacs is sponsored by <http://lowendmac.com/> and...
