Hi, i'm new here. just wonder if anyone can help me.

I run a 1.8 dual processor G5 powermac and have a PCI card that works perfectly in OSX10.3 but when I upgraded to 10.4 it suddenly stopped working.
[TC powercore element DSP audio production card]
I have tried lots of things (driver versions, re installs of osx etc etc) but to no avail.

I searched the manufacturer forums and the best everyone has come up with is the card is a computer itself and if it takes too long to boot up, the system has already scanned the PCI slots and moved on before the card is ready.

So what I want to do is stall the computer between when it initializes the PCI slots and when it checks them.

I have done a few searches here and found some good info (What is Mac OS X?) and tried the cmd+opt+O+F when starting up but no good.
It seems to be after the kernel loads that I need to pause things.
(I'm guessing around when the i/o toolkit loads)

I'm sure its possible and I found mention of cool developer/hacking tools that probably could help but I wouldn't have the foggiest idea how to use them and I don't want to hurt anything.

downloaded chud tools hoping they'd help but again couldn't really work them out without help.

Can anyone help?
Thanks

Not an expert but the only thing I can think of is putting some kind of timer loop in the startup script (think it's /etc/rc). Maybe a for loop to kill some time until the next instruction.
Don't know of any app/util which would do this.

Thank you very much for the reply

I had a quick look at the etc/rc file using a terminal editor.

I'm not sure which parts point to pci slots - I could see no mention of the programs I read about in the web site above (i/o).
(Is rc the script that controls the initialization of hardware?)
Also not sure what the script/command is to create a short loop/ pause.
