昨天在一台DELL台式机上安装esxi4.1失败（DELL 780/ E7500 Processor /4G RAM)，错误提示无法找到安装镜像。试过CD和USB安装，统统都失败了，所以估计应该是硬件兼容性的问题。
错误提示：
installation operation failed!
The installation operation has encountered a fatal error:
Unable to find system p_w_picpath to install. This is due to the p_w_picpath not being mounted correctly or the CD-ROM not being supported.
解决办法：
先安装esxi4.0，再通过升级至4.1
1) 通过vSphere Client选择Enter Maintenance Mode
2) 通过vSphere CLI升级，命令为 vihostupdate.pl –server <ip_address> –install –bundle <path_to_update_file>
3) 重启esxi服务器
4）下载安装vSphere Client 4.1
