i'm sure i had both hardware revisions of the 5.2 tested with the patched bios. but that was quite a while ago. so for the fun and for the pleasure i repatched both bioses again and uploaded them separately. find them on our download page (as usual).
please note that there's a revision 8.0a, too.
if you talk about the M810D you're talking about a PCChips motherboard. ECS' version of the board is called K7SOM+. ofcourse we have those bioses patched, too. i don't know if bioses are interchangeable between PCChips M810D and ECS K7SOM+. the only thing i know for sure is that the hardware revision of the board DOES matter when it comes to the bios.
so take Denniss advice and find your mainboard's revision first.
If you email me include [WIMSBIOS] in the subject.
