tips of si sandra?

Tip T2525 - Current AGP data rate not optimal, i.e. less than chipset’s maximum AGP data rate. E.g. current AGP data rate is 1x while the chipset and the AGP card both support 2x. You should get better performance with a higher data rate but this depends on the application.
Fix: First, use the PCI & AGP Information module to confirm that the AGP card also supports the maximum chipset data rate. If it does not, don’t worry about it. For non-Intel chipsets, make sure you install the latest version of their AGP mini-drivers. You should update the video card drivers as well. Some non-Intel chipsets can only work in 1x mode with some video cards.

Warning W2513 - The AGP bus is disabled.
Fix: If you have an AGP mainboard, you should get a AGP video adapter to take advantage of it. An AGP adapter would greatly improve 3D performance. However, it should still have at least 8-16MB of local memory

anyone know how and if i can do these tips?

Bit more info might help here, like what motherboard & graphics card you have.

Having said that, SiSoft Sandra isn't the most accurate diagnostics software out there anyway.

my motherboard is an msi ms-6775, and my graphics card is an ati all in wonder 9200 radeon 256mb.

Seems your board is simply "Made by MSI" for the likes of Time, Tiny, etc and MSI themselves don't offer any support for it whatsoever.

Go in to your BIOS and check that 8x AGP is actually enabled.

Also get a better diagnostics program than the piece of crap you have now (you know it's crap when it starts making comments like your AGP bus is disabled)
