Short Answer: Trust the kernel to do the right thing.
i think i can trust the kernel and redhat ;-)
Ok, but will the kernel know to turn DMA on or off? If /etc/sysconfig/harddisks was empty, would DMA be enabled on harddisks upon boot?
on my nforce1 - board
under phoebe he knows "NFORCE: IDE controller" DMA = on for all supported devices eg.
/dev/hdb:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 10011/255/63, sectors = 160836480, start = 0
under RedHat 8.0 "PCI_IDE: unknown IDE controller" DMA = off for all devices eg.
/dev/hdb:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 10011/255/63, sectors = 160836480, start =
