Hi all,
I've now managed to acquire a Powermac G4 MDD but unfortunately there are some issues with it, not least that it isn't the spec it was supposed to be, but foremost being that it doesn't seem to be doing what I'd expect it to on power up, i.e. giving some sort of output from the OF part of the process. However this hardware platform is all new to me so I may be overlooking something (hopefully).
So it seems to be the earlier type MDD: 867MHz processors, 2 Firewire ports, a GForce graphics card (yes I know that won't work with MorphOS, it supposedly had an ATI Radeon); it's got 2 sticks of DDR, and currently no hard drive or optical drive. When I power it on, there are no beeps (good) or chimes (bad?), the smaller fan starts straight away and then about 10 seconds later a jet turbine spins up (maybe I've been using a power-efficient, low-noise Windows PC for too long). But that's all that happens, I get no display of any kind from the DVI port, either connected into the HDMI port of my monitor via a DVI-HDMI cable or into the DSUB port of my monitor via a DVI-DSUB adapter and DSUB cable. All I can do is hold in the power button until the racket stops.
Here's what I've tried so far.
[list]Holding various keys (alt, alt-s, c) whilst powering on.
Removing the PRAM battery.
Connecting an IDE hard drive set to cable select (although I'm now suspecting it might be dead but it's the only ATA drive I've got).
Pushing the GFX card and USB card down to make sure they're in properly.
Pushing the DIMMs to make sure they're also in properly.
Removing the heatsink and making sure the CPU card is definitely pushed down all the way (although I've not actually removed it).
Removing one of the DIMMs (the one that was rattling behind the front HD cradle when I opened it up

).
Removing both DIMMs (thereby leaving no RAM installed).
[/list]
None of these actions has made any difference, I still get no beeps, no chimes and no display. I've spent a fair bit of time Googling and trying things and am rapidly losing hope of this machine working. But at the same time, I'm not familiar with the platform so whilst I'm expecting to get to any sort of OF prompt or output of some sort, is there something I'm missing? (Fingers crossed!)
Thanks in advance.
