redflag Dc5.0,Asianux2安装时无法创建文件系统，缺少scsi驱动解决办法

安装方法： 请将img文件制作成驱动软盘或驱动光盘，

在Linux下将img文件制作成驱动光盘的步骤：

1.将img文件保存到指定目录A中

2.在目录A中创建临时目录tmp

3.将img文件Mount到tmp目录中，命令为: mount megaraid_sas-v00.00.03.13-1-DC50-all.img tmp/ -o loop

4.将tmp目录中的所有文件刻录到光盘中即可

mkisofs -r -o cd.iso  tmp/

[root@localhost tmp]# cdrecord -scanbus
