    Re: Re: AGP question

    Guess I have a memory conflict not a hardware conflict.
    Video uses memory locations

    D0000000 - DFFFFFFF
    F0000000 - F0FFFFFF

    VIA tech CPU to AGP controller Uses

    000A0000 - 000BFFFF
    D8000000 - E7FFFFFF
    E8000000 - EFFFFFFF
    F0000000 - F1FFFFFF

    Any way to change any of these?

    Re: Re: Re: AGP question

    No, they're supposed to use the same memory locations, as it is an AGP card - AGP controller needs that too. Same thing if you had a PCI video card.

    You should also have shared memory with your card, AGP controller and PCI bus in A0000-BFFFF, which is the standard VGA memory area.

    I see your BIOS has an option "VGA: on", does that mean you have also an onboard graphics chip? If you do, try disabling it.

    Could find nothing in Motherboard manual about onboard graphics.

    I solved my problem by upgrading my Bios chip. New agp 4x card works now.

    hmm, i need help now, im running a radeon 9200se 64mb 8x in a 4x motherboard, if i buy a new mobo will there be any performance increasr? ie, a mobo with the nforce 2 chip and 8x agp.

    NO! Please do not buy a new motherboard for a 9200se. The card is slow as it is and motherboards with 8X AGP slots rarely improve video card speeds to the point you would notice in a game with that slow card. The only advantage you could get from a motherboard with a 8X video slot would be the boards newer chip-set which would allow the use of faster memory and drives (assuming you have the right processor) but only if you bought new memory and drives and had decided to over-clock your processor. What processor do you have and what socket is it?

    *EDIT* I looked at your profile, and I see that you have a 2800+ and all a new motherboard could guarantee you would be slightly faster video card, faster memory, (if you bought new memory or wanted to really overclock the old memory) more that 2 channel sound if you bought the right board and over-clocking your old processor to close to 400MHz memory speed if you bought a very good after market heat-sink and fan and memory. You can find old socket A motherboards with sata drive ports so you could get faster drives if you bought them and you could operrate a RAID array if you were really dedicated to your old procesor. /*EDIT* Big bucks = little gain in this case.
