I picked up some older Supermicro machines from eBay (GREAT way to get some real server hardware, btw), but they have aÂ VERY old IPMI firmware and no way to upgrade to a more modern version.
They can’t do standard virtual media — you have to specify a SMB share with an ISO on it to mount. Once you do that, you have to make it bootable in the BIOS and move it up the boot order.
I wasted about an hour trying to figure out why I couldn’t enable the device “PepperC Virtual Disc” in the boot order — the answer is, you have to use the ‘x’ key to remove unused devices from the 8 available boot slots,Â then you can select the PepperC device and use the ‘x’ key to enable it, and then you can move it up/down the boot order with the +/- keys.
Hopefully this saves someone else some grief, I was losing my mind trying to figure out the problem.
