hwconfig's Introduction

hwconfig

For check a Hardware Spec. & verify an environment by check-list

  • Notice!
    • Bin files for the RHEL Linux only if you need to use the hwconfig to the ubuntu, then you should install the lspci & MegaCli to the ubuntu by packages.

How to install

sudo mkdir -p /data
sudo mv ./bin /data/
sudo chmod +x /data/bin/*
  • Show up the HW Spec.
