iATKOS 5i on HP Pavilion DV4
 

Will iATKOS 5i work on a hp pavilion dv4 laptop if i run it off a 20gb external hard drive .
Its got :
2GB RAM
2.26 GHZ intel core 2 duo p8400 processor
Nvidia Geforce 9200M GS graphics card 1gb memory
Wifi is intel 5100 AGN

Is this sufficient to run iAtkos.
I only got a 20 gb hard drive because i will not be using it that often.
