Not directly. The D845GVSR has no SATA connectors or controllers. A third-party SATA controller can be added through a PCI slot.
No.
I am assuming that you are referring to The Intel® Desktop Board D845GVSR. This Motherboard has onboard intergrated graphics, but does not have an AGP slot available, However there are 3 PCI slots available. So the answer to your question is that without an AGP slot you are restricted to PCI or ONBoard Graphics with this motherboard.
You have to check the motherboard manufacture website for drivers compatible with Vista Home.
Yes. The Intel D845GVSR was one of the first Intel desktop boards to support LBA48. LBA48 addressing allows you to use drives large than 137 GB (127 GiB). Theoretically, you could install up to a 144 PB (petabyte) hard drive, but as 1.) These don't exist yet, and 2.) IDE will long phased out by the time they do, you will likely never reach the largest supported capacity.
No. The chipset is too old, and there isn't even a way to physically install one.
yes
Yes, it is compatible.
buy single 1GB ram and put it in single slot ... it works fine... I'm using 1gb ddr1 ram PC 333 on Intel 845 motherboard... its wrking fine...
No it isnt. You would either need to get a new motherboard or get DDR2 RAM modules to make it work. Heres the official intel page regarding your motherboard : http://ark.intel.com/products/22637/Intel-Desktop-Board-DG965RY
yes
Yes, the ASRock 775i65G LGA 775 Intel 865G Micro ATX Intel Motherboard is compatible withCore 2 Duo, Pentium D and Celeron D processors.
Processors don't connect to a motherboard, there are installed in a socket. What determines if a processor is compatible is the type of processor... PGA(AMD most of the time) or LGA(Intel) and the ammount of pins that are on the motherboard/processor.
