Hi,
I recently received a Socket 7 VA-503+ motherboard which used to have a AGP video card. I tried to install a PCI Video card but it will not recognise it. A friend mentioned that I would need a AGP card to boot up and then in BIOS switch to PCI.
I am not sure if that is true.
If somebody is aware of any method to switch from AGP to PCI without booting, I would be happy to try it.

If you can get it to show you the bios setup screens, there may be an option to enumerate PCI or AGP first...

Although it should eventually display on whatever card is in it...

------------------
When all else fails, read the instructions.

If the Bios was set to use the AGP first then yes you probably would need to change it before the PCI card would be recognized...you can try clearing the CMOS by either using the jumper (in which case you would need the manual...which can be found here (http://www.fic.com.tw/techsupport/motherboards/pentium/VA-503+.htm)), or pulling the battery. The exact procedure should be detailed in the manual, and it should also tell you if the AGP is the default or if there is an auto aetting.

If you put a GOOD PCI vid card on that mobo......it will at least take you [during post up] to the bios screen unless something else is wrong even if AGP is chosen in bios.

My PCI Video Card is a Number 9 Motion 771 and the Mobo compatibility has VC's after Motion 771. So I think I might have a compatibility issue also.

I am getting a AGP card from a friend tomorrow for testing.

Hopefully this should get resolved by plugging a newer AGP or PCI card.

Thanks.

Hi,
I tried with a AGP card but no success. The monitor when it is turned on has a green light initially and then after a minute turns yellow which means no signal received. I thought of replacing the cable from the card to the monitor. I found that the cable is hard stitched into the monitor.
It has no jack at the monitor end, so I do not how to replace the cable.

Any ideas.

Prasanna

Can you prove the monitor works on another working PC.

Hi,
I am unable to read anymore msgs from my server. I do not know why but I can post so anybody who is responding please send a copy to "prasanna.rao@att.net"

I have tried a 4MB ATI Rage Pro AGP Card. It still does not work.

I do not know what to try now.

Hey,

Couple of ideas.

First, clear the CMOS by either using a jumper on the motherboard or by removing the battery for a few minutes.

Next, or in tandem with above, get yourself the manual for that motherboard. I read where the motherboard has scads of jumpers. Could be that you will have to mess with a jumper to switch it between PCI and AGP. Maybe not, but it's a thought.

Go to www.fic.com.tw (http://www.fic.com.tw) and look for the manual.

Good luck.

Um, I must have been drunk at the time.

I switched back to my old mobo and the monitor comes on fine with the PCI card. The old mobo does not support AGP.

I am using a AMD 500Mhz CPU on the mobo. Would I have problems with the clocking as AGP is 66Mhz and PCI is 33Mhz speed.

I have hardcopy of manual but it does not talk about switching from PCI to AGP or vice-versa. I will try the CMOS stuff tonight.

More later.

I downgraded mobo to 66Mhz, so processor is at 366Mhz instead of 500Mhz.
Now Video comes up fine. I guess some AGP cards cannot handle higher mobo speeds. I will have to look for a video card which supports 95Mhz and higher.

Thanks for all your help.

AGP bus is already twice the speed of PCI bus, when you overclock the FSB you also OC the PCI bus ( AGP is a type of PCI )-and video cards really don't like it when you raise the bus speed!

If you want to OC your CPU, then DON"T do it by the FSB! you'll fry your perpherals too! http://www.PCGuide.com/ubb/eek.gif

There is probably a jumper that needs to be changed to activate/deactivate the AGP port. Then on the other hand if you have a Gigabyte Board, the AGP port is defective. I know, I have one!

Running that 500 CPU the Bus Speed would have probably been set at 100. The older Video Card just couldn't handle that much. As I recall PCI/AGP like to work on a 1/3 and 2/3 ratio of the Bus Speed. A FSB of 100 would give 33 and 66 to those puppies. Older video just couldn't hang with it. Luck.

Hi,
I was able to run at 66Mhz due to the memory chips being SIMM. I upgraded to 128MB SDRAM DIMM chips and I have PC running at 500Mhz
after a few hiccups.

The memory was the key to switching to higher speeds.

FYI : I tried 550Mhz and we are back to no-video. so I just ignored it and settled for 500Mhz.

Thanks everybody for your inputs.

Try to clear the CMOS using the jumper on the mainboard.
I am using a pa2013 mainboard using the same chipset as the 503. It works perfectly either with a AGP to PCI vga card.
