"Improper termination or faulty cable detected. Please rectify!" on console upon boot with Linux OS

Hello,
We have our internal wiki on a Linux OS machine. Nothing has been changed on the machine. Upon reboot, I see "Improper termination or faulty cable detected. Please rectify!". Also error message comes up for "connot find operating system". There is a RAID 5 configuration on the machine and there are 4 internal SCSI drives. I dont have a problem scrapping the machine altogeher, but want the info within.

Essentially what we want to do is to get to some of the Public folders in the machine and access it. I know how to proceed for machines with windows, but have litle experience with linux disaser recovery and also RAID. Any help would be apprciated to know where I can look first. Would I be able to take out the drives and terminate on another machine and expect it to mount? Please help!!
