[Request] Asrock G41C-GS add JMB362 Option Rom

I bought a pair of this sata 2/300 controllers, based on JMB362 chip: https://gd4.alicdn.com/imgextra/i4/54071…_!!54071293.jpg for cheap on aliexp.
I didn’t focus enough, to find that this little controllers doesn’t have any romchip, so they aren’t bootable by themselves.
So, I thought I would try to insert the correct JMicron’s option rom on the motherboard and see if it works.
But I can’t find anywhere the latest option rom file to download.
Also, this is the latest mobo (beta) bios: http://asrock.pc.cdn.bitgravity.com/BIOS…S(1.40C)ROM.zip
Oh, by the way: I want to add this controller to this motherboard since it has an ICH7 southbridge that doesn’t support it, unluckily.
