[CENTOS] Build onboard RAID with T1310M3 and install Cent OS 7.7

It's common sense for those who know it, but I was addicted to the fact that I didn't recognize it without a driver.

2. 3. Important: The logical drive created in 2 cannot be recognized by the CentOS 7.7 installer, so you need to install the driver.

3. Download RHEL7.7 SATA RAID RHDUP driver package megasr2 18.02.2019.0603.4fts-2.el7.7 for RHEL7.7 at https://support.ts.fujitsu.com/IndexDownload.asp?lng=COM

4. Burn the above driver to a USB memory using DDWin etc.

5. Insert both the CentOS 7.7 installer USB and the USB with the driver.

6. When the installation screen appears, specify the USB load containing the driver by referring to "When installing CentOS by UEFI boot" at https://qiita.com/heimaru1231/items/5c65d98570b996510e77. Once the driver is loaded, continue with c to launch the regular CentOS GUI installer.

7. Install by specifying the created logical drive
