SubjectRe: [LINUX-KERNEL] HDD Noise stopped with cat /dev/zero
Hahahah... exactly what my 386sx20 PS/1 does when I used to go into 
windoze screen savers... a sort of faint clicking/humming... definetly
the cpu, since none of the disks were being accesses and i dont have any
network cards... when i put my ear up to my machine, i could tell it was
coming from the direction of the cpu too... (not my speakers)..
