Hardware diagnostic program for Linux

[Cytochromec]

Howdy,

My tech's tell me they use programs in windows provided by Dell for hardware diagnostics (Harddrive, RAM, fan, etc.). What are some good programs for techs to use as part of the troubleshooting and repair process in the Linux world?

Such utilities are usually built into the BIOS on those devices. They are also generally useless for solving problems, IMHO
