Hi, There are some rumors about the lack of need for an RT patch with new kernel, after 2.6.26.xx for making (realtime) music on GNU/Linux. What is true about this? Thanks in advance, \r

BIOS and IRQ

by Grammostola Rosea

Hi, In my bios I' ve an option IDE Hard Drive Acoustics Mode which can be set at: [bypass] (now) [quiet] [Suggested] [Performance] What is this? Has this anything to do with the quietness of my hard drive? It a dell worstation 360. Also kinda dived into IRQs. Can someone say whether I've to change something?
