This package is a collection of tools useful for hardware troubleshooting and optimization (for ix86 machines):
irqtune: adjusts priority of interrupts (improves serial performance), scanport: scans for hardware not already handled by Linux drivers, memmxtest: a real mode memory test, with MMX support. You may want to look at package memtest86 as well. qic-02 driver and configuration utilities. Adds the qic-02 tapes support
Be aware that these tools require some knowledge of what are they doing to be used properly, not causing damage to your system.
Some programs that were previously part of this package have been moved to their own packages (hdparm, scsitools, memtest86)
