Hardly,you might be able to run,but it wont be usable and i doubt if u can enable aero interface.
Hardware requirements for a Vista Capable PC are a modern processor with a speed of at least 800 MHz, 512MB of system memory, and a graphics processor that is DirectX 9 capable.
A
Windows Vista Premium Ready PC has a good deal more requirements. It must have at least a 1 GHz 32-bit (x86) or 64-bit (x64) processor, 1GB of system memory, 128MB of graphics memory, 40GB of hard drive capacity with 15GB free space, a DVD-ROM drive, audio output capabilities, and Internet access capability.
It also needs a graphics processor that runs Windows Aero, which
Microsoft defines as a DirectX 9 class graphics processor that supports a Windows Display Driver Model Driver,
Pixel Shader 2.0 in hardware, and 32 bits per pixel.
The graphics processor for Aero also must meet the following requirements for graphics memory: 64MB of graphics memory to support a single monitor less than 1,310,720 pixels; 128MB of graphics memory to support a single monitor at resolutions from 1,310,720 to 2,304,000 pixels; or 256MB of graphics memory to support a single monitor at resolutions higher than 2,304,000 pixels.[/b]
In addition to speed up the whole things up, NAND/flash memory on platform (like
intel robson) or hdd (hybrid drives).
