Freebsd 5.x on Toshiba Portege 3500

[J. Kenney]

Good Afternoon All,

4.x boots/installs and works fine on my notebook (Toshiba Portege 3500), but
no version of 5.x has successfully booted (with/without ASPI, safe mode,
etc), but the strange thing is that if I load VMWare or VirtualPC 2004 and
try to install FreeBSD 5.x into the VM it also does not survive the boot up?

I was hoping that maybe someone has been able to get the Portege to boot,
and could help with advise.

Many thanks!

J. Kenney
