I used to own one of these motherboards many years ago, it was difficult to deal with mainly because neither PCChips nor ECS who used to make most of the branded PCChips motherboards provided a great deal of information on them. I usually had to due quite a bit of personal research and educated guesswork with dealing with any ECS made motherboard. If I were you before jumping to many guns I would investigate the ECS website for anything that looks like your motherboard ( it may not and probably doesn't share the same model # if my memory serves ). Be very careful of what your eyes see as ECS motherboards are notorious for being very similar between models but other then their apparent visual similarity, they are quite different. I.E. it could be quite easy to install a Bios update onto what you think is a particular motherboard due to its looks, but in reality the bios update would be for something quite different, which usually kills the motherboard of that age group.
However since you mention PCChips, this is their coverage of the related M748LT motherboard which is related but they seem to no longer cover the M748LMRT, which is why I suggested looking at the ECS site also.

I just checked on the ECS site and there no motherboards with similar model #s on their site. Do your best to use manufacturer website to get your drivers as many commerical ' driver finder ' sites are not near as good as they claim to be and can often lead to faulty information about drivers or chipsets used on your system, especially with these older motherboards.
I hope for you Good Luck as I suspect you will need it when dealing with an ECS or PCChips motherboard..
