It's the round shiny chrome disc on the motherboard. Remember if you change it you will need to reset the cmos in the bios.You can contact me and I will walk you through that part.

What is maximum GB supported for hard drive

Normally there is not such limit in recent moterboards, but if you used old motherboards which released during 2007-08 they can support upto 500GB per slot, and there is normally 2-4 slots for connection of HDD.

In this way you can have upto 2TB of HDD storage.

Did you fix your problem with the VKM400AM-S not booting, only beeping?

Probably your mobo does not support 1 GB RAM in one DIMM slot.. Check Motherboard Manual.
