Would OSX install on either of these?

Using ATKOS V1.0

For both I get the grey boot screen, Apple in centre, wait 5 mins and the 'No Entry' sign above the apple appears.

When rebooted with the -v option it gets to...

USBF: 1.397 AppleUSBOHIC.....
ApplePS2Trackpad: Synaptics TouchPad V5.9 (V6.2 with Acer)

... repeats

Acer seems to do the same.

I have tried the rd=disk0s1

But that still does not seem to have progressed things.

Any ideas?
