David,
Thanks. I'm actually pretty familiar with hdparm itself. My lack of
boldness was whether to push the envelope on this new SATA drive. Are
you running SATA?
I see some threads on the web where people are getting 120MB/S from
SATA, which is exciting. I just haven't pulled the trigger yet and tried
it.
Thanks,
Mark

Mark,
Try editing your /etc/conf.d/hdparm file and customizing for the sata drive.
I have something like:
# disc0_args=-d1 -X66
# disc1_args-d1
# cdrom0_args=-d1
# Or, you can set hdparm options for ALL drives using all_args..
# eg.
# this mimics the behavior of the current script
all_args=-d1 -c1 -u1 -Z
So when I run hdparm I get:
hdparm /dev/hda
/dev/hda:
multcount= 16 (on)
IO_support = 1 (32-bit)
unmaskirq= 1 (on)
using_dma= 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead= 8 (on)
geometry = 620/64/63, sectors = 2502308, start = 0
Try the hdparm man page for a complete listing of all options. If you know
exactly what your motherboard and hard drive support you can tweak it a lot.
NOTE: Do an rc-update add hdparm boot to get the parmeters in the above
mentioned file to work on bootup. WARNING be carefull because you can kill
or corupt the hard drive with unsupported options.
Good luck.
David

As I told him, get the newest kernel possible. When 2.4.20 was released,

Now
you throw in SerialATA support on top of nForce2 and you really
something
current. I couldn't get USB support to work with my nForce2 (MSI) based
board until I tried 2.4.23_preX kernels.

Hall, Alan, Javier and Jeffery,
Thanks for your help. I have now managed to boot my A7V8X-D
motherboard from the onboard SATA drive. It turned out that my 1st, and
most major problem was that I somehow ended up with multiple copies of
grub installed on the SATA drive. It gets a bit complicated to explain
where things are supposed to be in this setup, and all of the drive
partitionas, but obviously I confused myself in the process of bringing
it.
Anyway, problem solved and the machine is booting. Thanks for all
your help!
I am now running 2.4.22-aa1 and it's booting fine from SATA. I did
build 2.4.23-pre8 using my own quick configuration but there is some
problem there right now. I'll try that again later today possibly using
Javier's config file.
The initial SATA drive performance isn't bad, but isn't that great. I
haven't been bold enough yet to turn on any specific optimizations in
this new machine yet, so it will likely get better:
Gandalf root # hdparm /dev/hda
/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= 8 (on)
geometry = 155061/16/63, sectors = 156301488, start = 0
Gandalf root #
Gandalf root # hdparm -tT /dev/hde
/dev/hde:
Timing buffer-cache reads: 128MB in 0.34 seconds=376.47MB/sec
Timing buffered disk reads: 64MB in 1.78 seconds= 35.96MB/sec
Gangalf root #
Not bad, but actually not as good as the EIDE system I'm responding on
right now:
Wizard root # hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 1320 MB in 2.00 seconds = 660.00 MB/sec
Timing buffered disk reads: 140 MB in 3.04 seconds = 46.13 MB/sec
Wizard root #
Both systems are Athlon-XP and Asus motherboards (A7V333-X with a 2600+
vs. A7N8X-Deluxe with a 2500+ Barton) and both drives are 80GB.
Now, on to getting more hardware working and X running!
Cheers,
Mark
