View Full Version : MacOS 9.1 won't install on a Yosemite

07-31-2001, 01:28 PM
I've got a really weird problem going on: my little sister is currently using 9.04 as her OS on a Yose/400 and for some unexplained reason, each time she updates to 9.1, the following startup hangs just as it's about to boot the Finder.

I've tried installing it myself, starting with no extensions, only Apple stuff... and it still hangs. Most ominous.

She's got 2 PCI cards in her Yose right now: a Miles Bluenote and ixMicro TV. The prime suspect right now is the TV car, as it has a really old driver, but it still hangs when the driver ain't loaded.

Can a PCI card, just by its mere presence (no loaded drivers) cause that kind of crash?

Try pulling the BlueNote and see if you can get a startup. k

Hmm... Will try. Heck, Might as well pull all the cards out while I'm at it and put'em back in one at a time to se if it fixes a few things. <sigh> I just don't like merrily yanking PCI cards in and out. I keep thinking I'm gonna mess one up.

Still I'll have to wait for the weekend to try it out. I'll report again then.

Got a stupid question, though: Can the OS boot off a Slave IDE disk?

Faulty or otherwise incompatible PCI cards can cause problems, as during Open Firmware bootup the New World Macs build a PCI device tree.

You may wish to try resetting the Open Firmware, the method of which I have already posted elsewhere.

I had a similar problem, but my hardware is a bit different.

I was unable to boot my YoseG3/500 with my RADEON when the default MacOS 9.1 ATI drivers were installed. I hit the space bar on boot - disabled the ATI extensions (after much experimentation) and it worked fine.

Can you boot with extensions off?
You actually have to have 3 PCI cards - since the BNote & ixTV do not drive any kinds of monitors http://macgurus.com/infopop/emoticons/icon_wink.gif What is the video?

Can you clear the OF by zapping the NVRAM?

Actually, there are only 2 PCI cards (Bluenote/ixTV). My sister's Yosemite still boots off its OEM Rage 128 card (the one with the DVD decoder).

I tried booting off without extensions four times and it only worked on the second try. Don't ask me why.

I'm going to search the forums for that NVRAM zapping trick. Maybe that'll do it. I just have to make sure that I make a good backup of everything first.

Command-Option-P-R but hold down for 4 chimes - that should clear the NVRAM - I think 3 chimes only does PRAM...

Hold Command-Option-P-R from a Cold boot (From a full shutdown) to Zap the NvRAM. From a restart will only Zap the PRAM. You actually only need one additional chime from the startup chime in either case.

Thanks for the tip! http://macgurus.com/infopop/emoticons/icon_smile.gif

While we're on the subject, is there a page somewhere on the Web that lists all the different possible startup key combinations and their effects?

Mac OS Help should have them. Launch it from the Finder (Help in the Menu Bar), select shortcuts and tips, select keyboard shortcuts, select starting up. k

Righto - thanks for the hints and help!
