Hello everyone I have a big big problem. I just bought a digi 001 and installed the pci card in my mac G4, but now my mac wont power up anymore!!! The mac starts up when the pci card is installed, but as soon as i connect the pci card to the 001 unit, it powers of and wont start up. how is this possible? I already stripped down my computer completely and even disconnected the hard drive. so basically the digi 001 pci card was the only thing left in the mac (almost) But still it would not power up!! so i guess its not a conflikt with other detachable hardware. I really do not understand what is going on..... can someone pls pls help me. my details... Power Mac G4 Dual 1 ghz, mirrored drive doors. 2 X 512 Kingston RAM 80 Gig HD Digi 001 OS X 10.3.8

You might need an older OS. Check the compatability pages.

thanks for ur reply, but i dont think this is a software issue. Its purely hardware since the machine wont even power up. I also already checked the compatibility pages, and it should work just fine.....

Just to be certain you're doing this righht. The 001 should already be connected when you power up, you may have short circuited something. switch off connect it all up switch on. just like in the manual.

Absolutely! The 001 is most definitely not hot-swappable! It must be connected or disconnected while the computer is off. The 001 gets its power through the interface cable. Plugging it in while the 'puter is on may be causing a surge demand on the Power Supply Unit in the Mac which then says "Sorry, no can do" and promptly powers down. I'm just guessing, and hope you haven't damaged anything.

hi everyone thanks for all the suggestions so far. the card works fine in another pc, so the card is not the problem. also, i did connect the box b4 power up, but its no good. the mac wonf t start up. im sure its some sort of short surcuit protection or whatever, i just dont know what exactly. any more suggestions?

There was an issue with the motherboards in the early MDD G4's that didn't provide enough power to the PCI bus - this caused the exact symptoms you were describing, in that the machine would no longer power up, or ProTools would immediatly crash if you did manage to get it started up. One fix that kinda worked was to move the system drive to the secondary ATA bus (the one towards the back of the machine) - i believe this helped some users, but not all. The real solution involves taking the machine to an Apple dealer and having them replace the motherboard. You're probably out of warranty, so it'll cost you a few hundred clams I'd imagine.

hi guys i already tried the pmu reset, but it didnt help. it wouldnt work. and about the drive, do u mean the hard drive? would it help to switch that? how do i do that?
