We don't have device drivers any more, we have "Hardware > Abstraction Layers". I think the HAL is how the device drivers get to the hardware. It abstracts (for example) the stuff you need to abstract before you're done booting, it abstracts the mechanism for figuring out how to do task switching, it abstracts the stuff for dealing with the motherboard so you can tell what device drivers you need to load, and so on. It's a layer below the device drivers. -- Darren New San Diego, CA, USA (PST). Cryptokeys on demand. Sore feet from standing in line at airport security checkpoints: Jet Leg.
