Socket A was almost 2 years before PCI-E timeframe.

Were there by chance any later mobos that had Socket A as well as PCI-E?

How about this? its only 1x but looks like fits entire length PCB

No. Not even ASRock.

Best bet is to use an adapter:

Whether it works on an older motherboard, I don't know.

To use that with a video card, you are also going to want a riser cable that can supply the needed power to the PCIe card.

There are a few reviews of those on YouTube and the cards by themselves seem to have banding issues. I am guessing due to the fact that the PCI slot can't supply enough juice to the PCIe card.

BTW, those adapters use the same exact chip on them that you see on cards that have special edition PCI versions that were originally PCIe cards.

perhaps a agp to pci-e adapter instead?

None exist that can be bought.

Unless there was a late designed industrial Socket A board designed in the PCIE era I don't think any exist. I think late model Socket 754 might be the first PCIE boards (or socket 940 Opterons).

I don't think one such board exists. I never even heard of one, let alone come across one (and I did look for them).

Socket A would be roughly around the Socket 370/478 era when PCIe chipsets have not yet been available, so there's no Socket A with PCIe, same goes to Socket 370/478.

I think the earliest to feature PCIe slots by CPU socket are Socket 478/775 (for Intel) and Socket 754 (for AMD), and that PCIe actually came to existence AFTER those CPU sockets came out.

EDIT: Apparently there are a few i915 (and some others) boards for Socket 478 as Srandista pointed out, but they're still quite uncommon compared to those of Socket 775.

There are a few late Socket 478 with PCIe support.

Interesting, so there really are some i915 (and others) boards for Socket 478. For quite a while I thought PCIe was only for Socket 775 and later.

But again, as Socket A was relatively earlier I don't think there'd be any PCIe chipsets designed for it.
