# Second / Third Install

During the second /third install, I believe I focused on flashing the GPUs
using the `amdvbflash` tool, the successor to `atiflash` that is
a command-line Linux tool.

My hypothesis was that the overclocked BIOS was preventing kernel drivers
from detecting it with `clinfo` or `rocm-smi` but I now consider that unlikely.
Such an failure would have been unstable performance.

The cards were not detected and the driver modules not loaded in the kernel
at all .

## PCIe Level Gen 2

There appears to be a speed negotiation setting in BIOS for communication
over the PCI Express bus.

One forum thread recommended setting it to Gen 1, but I haven't found
any issues with speed connection so far. I might try it again later.

## Netboot

I set the BIOS / UEFI setting to Boot-on-LAN, which I assumed was 
the same as Netboot, but continued getting to GRUB.

Perhaps I need to disable all the other boot volumes in order to
get Netboot into the boot order. Something to try later.
