Tyan Tachyon G9600 Pro Graphics Card

[Jab45]

I hope to God that someone can help me.

Yesterday I received my first ever graphics card and I was hoping that this weekend would be spent in FlightSim heaven.  However, I cannot get the damn thing to work.

I have a non-Intel based chipset (Via KM266) on a Gigabyte (GA-7VKMP) MoBo.  I have downloaded and installed the VGA (Virtual GART) drivers from the Gigabyte website but this has done nothing to help.

When I have the card installed, and go to boot, the boot process doesn't even start and there's a nasty two-tone alarm that comes from the board (like an old police car siren in SloMo).

Nowhere in my Bios is there a facility to disable the VGA and clearing my CMOS (as someone suggested) does nothing to help.

The Graph Card is fine as I installed it into an Intel-based machine for the purposes of error deduction.

My machine meets, infact exceeds "System Requirements".

So what the %$@! else am I supposed to do?  

All comments gratefully accepted.

Yours, a pissed off simmer.   :-/

It could be possible that there is a hardware conflict or a driver problem.

Jab45,

Does your motherboard originally have "onboard" video?  Likely you will have to go into your setup upon bootup and "point" the machine setup to the agp video card (it is agp?) instead of the onboard one.

You also likely have to set the video apeture in setup.  This is set to match your cards memory..... 32 Meg......64 Meg.... 128 Meg.....256 Meg.

And you also have to sometimes set the agp (2x, 4x, 8x) speed manually....it sometimes doesn't autodetect.

All I can think of.


best,

can you get into the bios? if you cant there should be a jumper on the motherboard that clears the cmos... just have to take it out for a couple of seconds then put it back in.. will restore all defaults so you can go back in and change it. also you didnt specify what version of windows you were running. if its win 98 check that each component has its own IRQ not shared.. this caused troubles on my old machine but doesnt matter with xp

Thanks to all for replies.

Point taken about Video Aperture Size.
OS is XP so I'm not looking for shitty OS problems.
Yes it's got onboard graphics and this is the crux of the issue; how to disable it - there's no clear option in my bios that allows me to do this.  Jumpers are not an option with this board.

I am beginning to think that I will have to go out and buy myself a decent board with decent bios and functionality that's reqired these days.  I only bought the board this year and find it incredible that I should be having such a drama over what should be a simple upgrade issue.

I'm off to play Space Invaders on my BBC Micro!!!
