grub reinstall / grub keeps rebooting

[Riccardo Mottola]

Hi,

I installed everything on a "host" machine (same architecture as my 
target box, just more ram and more Mhz). I end up with something bootable!
However if I put the disk in my original box, it just keeps rebooting, I 
don't even get the grub screen. Thus I suppose it is grub that forces 
this continuous reboot cycle?

Are there "options" when configuring grub? Something architecture 
dependent? host cpu is PIV, target CPU is PII, but they should have both 
the 686, ia32 arch. set. What's the best way to reinstall grub?

Thank you,
Riccardo
