Hello,

Upon rebooting my portable I get these settings:
/dev/hda:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 16383/255/63, sectors = 60011642880, start = 0

I then issue: hdparm -d 1 -A 1 -m 16 -u 1 -c1 -a 256 /dev/hda

Which results in:
/dev/hda:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 16383/255/63, sectors = 60011642880, start = 0


So far so good. I need to stress test the HD to make sure performance
is good. However on a P4 (3GHz) portable with 1G of ram, I never get
close to using the drive. This is good news because the 2.6.11-gentoo-r6
kernel is really smoking for me, but, I need to test these HD settings
to be sure they are good.

Last, when I issue: 
hdparm -k1 /dev/hda I get:
/dev/hda:
 setting keep_settings to 1 (on)
 keepsettings =  1 (on)

But upon reboot, I'm back to:
multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)

How to test the drive  performance and make the HD settings permanent
has eluded me. Ideas are most welcome.

James
