I think I killed it...

My PM9600 is not well...  I had it running OK with a VooDoo3, FWSCSI 18G HD, USB and 280MB RAM on an XLR8 Carrier 500MHz G3.  It was running OS 9.1 and seemed OK, but I had a R7000 card and a new ROM chip.  So I soldered it on and was able to flash it.  It a couple of boots to get it to recognize as the screen, but it worked. 

I then tried to install the drivers, which said it needed 9.2.  So I used OS9 Helper and 9.2.1.  After that, the screen never came back.  I have tried 3 known good video cards and none work.  I tried restarting several times and it will boot, I even heard it boot all the way to the desktop and pushed the power button and Return and it Shut Down, so I think the 9.2.1 is OK.

After rebooting several times, wiping the PRAM, replacing the battery, I get nothing.  The hard drive won't boot, the display is dark and now the startup BONG is much, much quieter.

Any thoughts on what to try or what I may have fried?

Re: I think I killed it...

Been able to confirm the R7000 card is good and works.  I moved it to my G4 and loaded 9.2.2 drivers for it.  So, I have a good 64MB PCI vid card for an AGP mac :-S

I am starting to suspect the power supply.  Most likely the 3.3V rail went down, that seems to explain why the video doesn't work and I imagine other onboard components ride the 3.3V rail?  (sound?, PRAM?)

Re: I think I killed it...

Tried the Cuda, changed PRAM battery, let it set without the battery for a while.  Aside from the one boot with a blank screen, nothing.  Guess I can't rule out something shorted.  I am going to let it set over night and see what happens.

Re: I think I killed it...

Are you sure you need OS9Helper with a G3 upgrade?

Re: I think I killed it...

the cpu upgrade may be the issue, especially with any updates.  Whatever new install is needed with it should be redone when software is changed.  My 7500 does the same thing when the battery dies.  Mine is easy as I just start from OS disk with on board video then restart off hard drive which is all set up with the software for the G3, then update those drivers just in case then restart and everything goes back to normal.

Re: I think I killed it...

My 9600 with the R7k sometimes needs to be powered on, powered off, and powered on again in quick succession.  If I just power it on the first time, it gets the behavior you describe.

Re: I think I killed it...

I don't really know why, but it lives again.  I tried resetting the PMU/CUDA switch last night and it fired right up this morning.  This evening I put the R7000 in and bam, it is on.

Re: I think I killed it...

So I just picked up a PowerWave 604/150 (labeled 132, but had a 150 board).  After pulling the cards, evicting the dust-bunnies and replacing the battery, it did the same thing my PM9600 did.  Boot, but no video.  I saw Schmoburger's post on 68kmla (and bbraun's post above).

The one thing that fixed both of mine was to pull the battery for 10 min + and reset Cuda.  They both booted with video after that.

Might be something about them getting old and creaky, but this seems to be a common/more frequently reported issue.

Re: I think I killed it...

The on/off/on trick bbraun made reference too above is a workaround that is faaaairly specific to the 9600 best i can tell and is used to get round an initial failure to boot to post which is the result of a removed or discharged PRAM battery. Not entirely sure what causes this quirk, however it is fairly predictable in both cause and effect. Ive not had similar issues with any of my 73/5/600 machines and do not own an 8600 to test whether it has the same idiosyncracy.

Best I can tell though, in any case this is unrelated to the inability to boot with certain video cards which, as you know already has been a problem which my 200MP is afflicted with. The fact that a faulty Rev.2 Rage128 card from a Yikes tower works but a known working Rev.1 card from a Yosemite does not, further adds to the confusion as to why this is a problem at all.  As it stands, I have not gone to any further depths to diagnose it as I aquired an 8MB twinturbo128 card (OEM fitment in Kansas 9600's) which works perfectly. At some stage though I would like to get to the bottom of why 9600's seem to reject certain video cards for no apparent reason.
