I not exactly sure what you're asking, but yes...there is a driver for a Radeon HD 2400 Pro. Go AMD/ATI's website here: Drivers & Software, choose your OS, then choose Radeon, then choose Radeon HD 2400 series. Incidentally ATI just released new drivers today.
If you're looking for the HDMI drivers, you can use the ones from Realtek. However, the default Vista drivers should have installed once the card was plugged in.
Again, not sure what you're asking since there's no attachment supplied.
If you have a 2400 AGP you will need to get the drivers from the specific manufacturer of your card. ATI does not officially support 2400 AGP and only offers PCI-E drivers on their site.
