G4 Digital Audio Sonnet Encore upgrade

[Firebomb]

Hi,


Can any one help? This might be a familiar one to some of you and I’ve trawled the forums and acted upon many of the suggestions given but to no avail!
I’ll be brief, I’ve managed to get hold of a G4 Digital Audio and have upgraded it for my son.

533mhz
1.25 ram
USB 2 6Port PCI Card
Nvidia FX5200 256Mb AGP Graphics Card
DVD rewriter
OS X G3/G4,Airport Extreme PCI Wireless Card
New CMOS Battery

No discs with it. But have installed Panther and added a second bootable drive with 9.2.2

All working great, so when opportunity came along decided to get my hands on Sonnet 1.8 encore off e-bay (Actually turned out to be a OEM product with a gold heatsink but am assured is identical to Sonnet Encore ST G4/1.8GHz ) I grabbed it. 100% pos feedback - so think the dealers straight.

I cannot get this thing to work! Applied the apple 4.2.8 firmware and the Sonnet firmware update. (I’m told that the firmware update for OS X is all you need these days, however, when that didn’t work I sorted out the second drive with OS 9.2.2. No joy from there either.

I’ve stripped out any cards that might conflict, I’ve zapped the pram, blessed the system folders reinstalled firmware – nothing just get the chime and a blank screen, although can hear the fans and drive kick in. Any of you guru’s able to help?

Cheers
