OK, so I tried to follow this guide and I got my 4 values of 0x533, 0x534, 0x535 & 0x536, but when I boot into RU and searched for IntelSetup I find it and go into it. But how do I use the HexEditor to change those values? I don’t know how to convert those to hex, thanks. He says the variable is an address, how do I know what address it is? Thanks.
EDIT, I tried to use the setup_var IntelSetup 0x537 0x0, but all values were already set to 0x0, oh well, I give up now. At least I know PCIe slots 1 and 3 can see all 4 drives on one card as I moved them around to see what ports worked.
