PCI-E 2.0 Compatibility issue with PCI-E 1.0a

hello

PCI-E 2.0 Compatibility issue with PCI-E 1.0a

wants to buy an 8800gt, 9600gt or HD 4850 for my old PCI-e 16 motherboard. The only problem is that his motherboard (MSI MS -7184 with game with is HP pc) only supports PCI-e 1.0a.

This is a problem as according to Wikipedia is that “PCI-e 2.0 is backward and forward compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and v1.0, and vice versa. In some rare cases it is possible that a PCI-E 2.0 card will not work correctly on a PCI-E 1.0a slot. This is only limited to certain video cards”.

There a way around this by flashing the bios but I don’t want to voided his warranties.

I mostly want the 4850; I don’t not want to buy an incompatible good.

So

1) is my PCI-e 1.0a motherboard compatible with the new PCI-e 2.0 cards

2) I reads somewhere that only VIA PCI-e 1.0a. Motherboards (what is that?) have problems while Intel and AMD chips (my chip is AMD/ati chipest sheet xpress 200) work fine, is this right?

Thanks for your help

HP has a tool for flashing the BIOS and using that won't void the warranty. Even if it did you could just flash the BIOS back to the old version if he ever needs to send it in.
