I tried it without sucsess:
HDIO_SET_DMA failed: Operation not permitted
/dev/hda:
setting 32-bit I/O support flag to 1
setting multcount to 16
setting using_dma to 1 (on)
setting keep_settings to 1 (on)
multcount = 16 (on)
I/O support = 1 (32-bit)
using_dma = 0 (off)
keepsettings = 1 (on)
Acording to documentation/ide.txt in kernel 2.4.4, I should insert the ide.o
module with "idex=dma", how do I do when the module is built into the
kernel? Is it the what the first error line says? BTW: it's a mandrake 7.2
with official kernel builed by hand with gcc 2.95.
