Hi,
I'm new to the list but have been working with PCI PowerMacs for a long time. I've come up with a problem that I've never seen before and I thought maybe someone could shed some light on it - soluble or not!
You probably don't want to read the whole backstory, but I'm left with a Powercenter Pro 210 (Catalyst motherboard) that will start with a good chime and let me get into Open Firmware (via the serial port), but which I can't then boot using any kind of media - HD, CD, floppy.
I don't understand how I can get this far but not all the way. Could it be that my ROMs are blown or something like that? Does anyone know what the machine needs to boot fully that isn't necessary for OF, and hence what could be broken?
Thanks,
Jeff

If it has the equivalent of a CUDA switch I would press it .
Check the PRAM battery and or Zapp it.

Thanks, I've done all the usual stuff like CUDA, battery, PRAM, removing extra hardware and so on - many times!
The problem became apparent when I took the machine down after it had been switched on and running perfectly for about two years (as a server). I'd had a G3 upgrade in it that I wanted to try in another machine (it works), and when I put it all back together again it wouldn't boot from the Adaptec SCSI card that it came with.
Not a problem, I thought, I'd just boot from something else and reset the startup disk. However, I've never been able to get it to boot again, although as I say the startup chime is good and Open Firmware seems fine so there can't be very much wrong.
It just seems to me that during those two years something may have duffed out that is needed for the boot process to run, but I don't know what to try. ROM replacement? Mobo from eBay? I don't want to abandon the machine as it so nearly seems to work!
Thanks,
Jeff
