The minimal system requirements demand updating with 9.0-RELEASE

[Mr Dandy]

Hi

According to http://www.freebsd.org/doc/handbook/install-hardware.html" 
"
Both FreeBSD/i386 and FreeBSD/pc98 require a 486 or better processor and at 
least 24 MB of RAM. You will need at least 150 MB of free hard drive space for 
the most minimal installation.
"

At present, the minimum volume occupied with system without a choice of 
components (src, ports) occupies ~450-500 Gb (i386/amd64). 

However, bsdinstall doesn't install system if a hard disk less than 1 Gb
