ServerGuide is an installation assistant that simplifies the process of installing and configuring Lenovo x86 servers. ServerGuide goes beyond hardware configuration by assisting with the installation of your operating system, the latest system device.
Its been a few years since I last touched one of these system. But make sure that the boot device is pointing to the raid card. It should take about 20 minutes to boot into the bios (just kidding but it will seem that way). If I remember correctly you could change what was the focus of the boot.
If you can boot off of cdrom you could use something like BartPE to boot the system (this is a maintenance tool). If you can see the hard drives in bartpe then your raid controller is setup ok, then I would focus on the boot device order. Also make sure you are running the current bios 1.17.
