   Jak zjistit jak se dohodli  jadro s radicem a s
diskem pro bootu? V jadru mam zakompilovano "Use DMA by default",
ale cat /proc/ide/hda/settings pise (krom jineho):

name           value           min    max       mode
multcount              16      0       16       rw
pio_mode       write-only      0      255       w
using_dma               1      0        1       rw

Neboli pio_mod je mozne pouze zapisovat/nastavovat, dma zapnuto,
multcount na maximum. Jak overim, ze je to doopravdy maximum, co lze z
disku/radice "vyzdimat"?
