Jumpy Audio CD playback

[confus-ed]

..With regards to the technobable, i am always keen to know how something works, i think it usually gives a user more of an affinity with a tool if thet know in depth what it actually does. im not saying ill deffinately fully understand all of it but it is nice to know, so long as you dont mind explaining it to us simpletons!..

OK for HAL's ..

& a bit of pure technobabble ! .. provides the most basic operating system functions, such as first-level interrupt handling, deferred procedure call and thread scheduling, and synchronization primitives. (its the control inferface between bios/hardware & your operating system )

If you turn ACPI on or off you change what happens when devices are added that use duplicate IRQs (Interupt ReQuests) which in turn may affect your pc's ability to 'see' (detect via pnp) the items via device manager (so it can't use them) - this can be both an advantage or dis-advantage, depending what you are trying to do.

But I can't think what to add to help you much ...

Perhaps lack of codecs since you reformated ?

Do you know how to check to see if dma is enabled ?
