In my Device Manager under System Devices I have an entry for:

SIS Accelerated Graphics Port.

How do I know whether my computer accepts either AGP or PCI graphics cards?

Take the cover off your case. Look at your bank of slots. If the
slot at the top, nearest the CPU, is different from all the
others, it is an AGP slot.

Be careful if you use software to identify the slots as recommended
elsewhere in the thread. A number of motherboards have buit in AGP graphics
systems so dont mistake it for being able to put an AGP card into the
machine.
Get a motherboard or computer manual and read the specs, look in your
machine, or look at the motherboard/machine makers website. Or take the
cover off and look.

It could also be a PCI Express slot - they look different too.

The safest way for a novice to tell the difference would be to read
the motherboard's manual, if it's to hand, or use a hardware reporting
software tool like AIDA32. Actually, ADIDA32 may have been
discontinued before PCI Express, you may need a newer one.

Also, a lot of SiS SVGA is built-in, so you may have built-in AGP SVGA
and no AGP slot at all. This fails the "is the top slot different"
test by appearing to be a pure PCI, no AGP system.

If the reason you need to know is to add an alternate SVGA card, then
you also have to know which generation of AGP it is - i.e. AGP, AGP
2x, AGP 4x, or AGP 8x. This is not because you need the speed; it's
because these may vary in operating voltage, and the wrong card in the
wrong slot would likely fry the motherboard, SVGA card, both, or more.
