# 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.
