What are the minimum specs of leopard on a legacy machine?

[Tiezep]

hiya, now that I have successfully installed hack os tiger onto my toshiba A55 (working sound too) I thought I would give leopard a go too (more future proof)

 

so I gave it a shot and for some reason I can't get it to boot up. I will get to the blank white page with the apple logo with the spinning... thing, and it will stay there, also I can't hear the hard drive spinning at all (tried 2 hdd's now, one of which I know works, also re-burned the dvd)

 

the specs on this machine is a 1.5 ghz celeron, 512 mb ram, intel gme 855 chipset.

 

also the disc is ipc 1.5.6 ppf5 final, and I always choose the voodoo kernel, but what smbios should I use, and what what kernel should I choose for the ide hdd?

 

thanks for any help offered,

-Tyler
