I did a little checking and JMicron says NOT to use their Firmware for onboard mobo controllers. JMicron says they're for their add-on cards:
"The JMB363 Option-Rom is for the Add-on Cards.
For JMB36x on board customers, please contact with your motherboard manufacturer for the system BIOS update."
So, 1 firmware file is out. BTW, I looked inside the latest Station-Drivers JMB36x firmware file, jmb36x_flash_1.21(www.station-drivers.com).zip
. I can't even FIND the actual firmware content bin file inside the ZIP file. WHERE IS IT?! I also looked at the Marvell firmware and it's pretty convoluted. I'm not sure I want to use that file either. You're really taking a chance if you use the Station-Drivers.COM firmware files. That's my 2¢
This is Asus's fault.
If they continued to support their motherboards, even after they come out with later models, we would not be having this problem. Da** them, da** them all to h***!
