In linux kernel since version 2.6.20 (release Date: 2007-02-04)
Prior to kernel version 2.1.112, Linux used to automatically use
DMA for IDE drives and chipsets which support it. Due to concerns
about a couple of cases where buggy hardware may have caused damage,
the default is now to NOT use DMA automatically. To revert to the
previous behaviour, say Y to this question.
If you suspect your hardware is at all flakey, say N here.
Do NOT email the IDE kernel people regarding this issue!
It is normally safe to answer Y to this question unless your
motherboard uses a VIA VP2 chipset, in which case you should say N.
