Interesting issues with iDeneb 10.5.6

[IT recycling]

A group of us have been messing with Kalyway 10.5.2 distro and more recently iDeneb 10.5.6. Firstly, here's my history: I', currently running a couple of macbooks, a macbook Pro, a couple of G4 Dual 1.25's all for work. Have the following 2 builds running for comparison:

 

HP WX4400, Core2Duo 2.4gHz, 6 gig ram, 3 x 250gig SATA, 2 x Dual head Geforce 256meg cards with 4 x TFT's, buetooth, 10/100 ethernet (Broadcom), firewire card, USB 2.0). Kalyway 10.5.2 Basically, a complete setup without sound and occasionally crashes (usual mac error- you need to hold down the power button to restart your mac- kind of stuff you get with bad memory blocks!)

 

Dell Optiplex 655, core2duo 2.66gHz, 2 gig ram, 2 x 250gig sata, on board graphics, ideneb 10.5.6 distro.

 

The above 2 x units were a clean, issue free install.... rather like re-building a mac!... actually exactly the same...

 

However, I decided to take this one step further and try an install on Intel Xeon servers that I've got lying around. First off an HP Proliant G5 3.0gHz Xeon Dual Core with 4 gigs ram and 2.5" SAS drives- no joy with either the Kalyway or iDeneb distros.

 

Secondly a G4 HP proliant with 2 x 3.0gHz Xeon server with 2 gigs ram and Ultra 320 scsi hot swap drives- again no joy with either distros.

 

It's not that the servers won't see the install DVD- they both go to the Apple logo with spinning disk, indicating that they're booting, but just sit there doing that forever- nothing else, no blue screen with apple logo, just the initial grey screen, grey apple logo and grey spinning wheel.

 

Am I missing something here? I've pulled the SAS controller, but this did nothing, so I'm guessing it must be the CPU's. However, from recollection, Apple have Xeon servers available, so this should be a runner! Do I need to switch kernel prior to boot (ie to voodoo?). If so, how do I do that?
