Ok, so I stubbornly wanted to make this work, and did! SO in case anyone else is struggling with the same board…
I had to install from a SATA dvd-rom drive, the USB would just not work with this board for some reason. Once installed, then if you have 4 nics (1 onboard, plus daughterboard w/ 3) then you also need to disable the parallel port on the integrated peripherals setting in the BIOS.
If you don't, this gives you an irq 7 interrupt broadcast storm error when plugging into re3 (nic 3). Once I did that, I finally got this to work!
