Thank you LonelyTV, you were right. The processor was 64bit capable.
the mountain lion instant reboot problem was BIOS setting.
Judgus // please confirm memory execute protection was enable in CMOS
after setting this, i was available to boot into installation screen with only npci=0x2000 (without arch=i386)
after installation done , I'll post another comment.
Ok hill33- well done mate!!! After I enabled memory execute protection, I rebooted with the ML ###### usb plugged in and it went straight to the install window without any boot flags. Mountain lion is installed now after many many many many attempts, but at this stage I have to use -x to get into it. So a few more things to sort out
Yes I also installed the
TSsync.kext to stablize the desktop
