hello, i am booting linuxbios from compatchflash and skip initialization of my additional hdd for faster booting (using kernel-commandline-argument "hdc=none"). after the system is up I register the hdd using
#hdparm -R 0x170 0x376 15 /dev/hda
everything works fine, except after enabling the drive this way I can't put it into dma mode, hdparm produces error like this:
# hdparm -d1 /dev/hdc
/dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off)
I am using elitegroup/p6stp-fl, sis630, sis5513 as IDE-controller
ps.: Bari Ari, did you find any solution to your "ide-hotswap" problem, please let me know!
thanks Felix Kloeckner
