Hey there, I posted this on The 6400 Zone, but you guys seem to be the System 7 experts, so here's a cross-post: Hello, I'm having all sorts of troubles when trying to install Mac OS 7.6.1 on a Performa 6400/180 that was given to me the other day. It came with 9.1, but it felt a bit sluggish to me, so I tried to install 7.6 using a 7.6 CD, but upon booting, it gave me a "This startup disk will not work on this Macintosh model. Use the latest Installer to update this disk for this model." Well, that's weird. Apple says 7.5.5+ should work just fine on the 6400. So I made a bootable 9.1 CD using the 9.1 System Folder that was already on the hard drive, booted off that and tried to run the 7.6 installer. It ran fine. Then I ran the 7.6.1 updater. Also ran fine. I rebooted the system and got the same "This startup disk will not work on this Macintosh model. Use the latest Installer to update this disk for this model." message. Any ideas of what could be wrong? Obviously, running the 7.5.3 installer that can be downloaded freely off apple.com doesn't work (Installer doesn't recognize the Mac's model). By the way, this 6400 doesn't have a floppy drive. The previous owner said it broke and that he probably threw it away. I have plenty of CD-Rs, but making bootable CDs is quite annoying, as it requires booting using the 9.1 CD I made, drag the System Folder into Toast, make an image, transfer that through Ethernet to my Macbook and burn it there. Thanks in advance. Any help would be really appreciated, as I have no idea of what could be wrong. |

I personally have 7.6.1 running on a 6400. It boots and installs from a 7.6.1 retail install CD just fine. Perhaps you should just seek one out on eBay. Some systems will not work with 7.6(.0) they need to have 7.6.1 installed directly. Also, what is this 7.6 CD you have from? Another computer? Or is it from a retail boxed copy of System 7?

I thought it was a retail one, but it probably came from another computer, most likely a 68K one. Which would explain why it refuses to boot off it. I think I'm done juggling around with System Folders and System Enablers, I suppose I'll just have to get a CD off eBay if I really want 7.6.1 on this. I need to ask the guy who gave me this 6400 if he still has the original installation CDs for this. What does the 6400 come with? 7.5.5.?

The 6400 shipped with System 7.5.3 using system enabler 410. It should start from a 7.6 universal installer CD. Sometimes older CD drives have problems reading burned CDs. Some are old enough that their firmware does not recognize a burned format. bill

I wonder if you ever figured this out... I had trouble on a PowerBook Duo 2300 I obtained. It turned out that the hard drive was formatted as Mac OS Extended. Doh. Reformatted, installed, and it works!

Quote from: "wove"
sometimes, if you burn the CD at the "speed" faster than the CD ROM limit, it can not be recognized. e.g. the 6400 built in CDROM is 8X, so, better use toast to select the speed burning at 8X or 4X or even 1X if you could find some very oldies CDR which still support that low speed burning. So, I have 1 time to buy a small quantity of 4X CD-Rs and use it very carefully with the real necessary disc for my classic macs.

Strange. I've never run across this issue. However, I've never attempted to create a bootable CD-R either, but all my discs--whether burned at 18x or 36x and everything in between--read just fine. However, that said, I always use a newer Macintosh (a G4 Powerbook, to be precise) and create an image in the Disc Utility, then erase the image with standard HFS. I would imagine that may have something more to do with it than what speed the disc is burned at. Then again, my experience is limited to the CD-ROM drives that come standard with pre-G3 PowerPC systems.
