Mac Pro 1,1 Boots Windows, won't install Lion

[monokakata]

I found a Snow Leopard DVD and, wonder of wonders, it seems to be installing. I'll report back in "about 39 minutes."

It installed and SL boots, but the response to KB or mouse inputs is measured in minutes, it can't find the network, and so on.

But at least it boots.

Many magical manipulations later, I have a running SL system. It's not quite right but almost.

If it runs OK for a few more days, it goes on craigslist. I'll let the buyer install Lion. This sucker's staying a SL machine.

I'd be happier if I understood (a) exactly what happened, and (b) exactly what fixed it, but I can't say I do.

My advice to Mr Zarniwoop -- try resetting the SMC with the internal button, as 666sheep suggested (thanks, 666sheep). I did it several times, and probably one of them caught. At first it didn't seem to be making a difference. It wasn't smooth sailing after that, but it definitely got me beyond the DSMOS barrier.

Later . . . I fixed the monster keyboard/mouse lag by realizing the no FW drive I attached would work, which led me to something on the Apple Support site, which suggested removing all FW-related kexts from system/library/extensions. I did so and now the thing boots with lightning speed. The FW hardware must be hosed in some way.

Although I have a 2 year old Mac Pro running ML, I also have an older Mac Pro that matches your specs exactly. The other day, the HD died. So I replaced and used my SL disk to reinstall. Then a software update to get it current.

On my newer Mac Pro, I had the 4.75GB Install Mac OS X Lion App, so I copied it to a disk and plugged it into my old Mac pro and went to install Lion there. The whole process looked normal until the restart when the Mac turns back on it simply returns to the SL desktop like nothing happened. I tried it 3 times with same results.

So I copied the 4.75GB Install Lion App to the desktop and ran it again and it installed perfectly and am now back to Lion.

Perhaps if you dragged the disk image to your desktop and gave it a try?

Hope this helps.

Thanks for the advice.

I never tried to upgrade, but I think I might as well. I was trying to do only clean installs (for Lion) and they wouldn't take. Maybe I'll take a spare disk, clone the SL disk, and try to upgrade it.

I can't remember how I installed Lion in the first place (in 2011). I had been remembering that I did it cleanly, but maybe I did an upgrade.

No action on craigslist at all, so I might as well mess with it. Of course the universe being what it is, as soon as I start fooling with it, and it's not responding, or I have to revert to SL, somebody's going to call and want to see it ASAP.

Probably the same way I did - from the App store as a $19.99 download. That's how I had the file. It's the last version that works on those Macs.
