The Findpart output is not very readable since it was edited, and
parts needed to suggest an Editpart command to fix the problem are
missing. If you post the entire output, I might be able to help.

Single Board Computer -- basically a computer that is targeted towards doing
one thing, and is much, much smaller than your typical PC box. Some are
targeted towards people who design embedded computers (and basically want to
bread-board and/or debug the design, which will then be manufactured in quanity
later). Because you don't get the economy of scale that you get in the PC
arena, SBC's do tend to be pricey.

Subject: Re: Hot-swapping IDE drives
Date: Sat, 28 Apr 2001 01:33:31 GMT
I think hot-swapping drives might prove a mare's-nest of trouble. I would
try adding another HD controller so that I could have more drives in the
system and then do the swapping after it was turned off. Or you could find
a fast CD-RW drive -- I recently noticed 16X write / 10X rewrite -- and
swap CDROMs. There are also LS120 drives (my choice), zip drives, and a
variety of tape and magneto-optical drives.
However, if you have an appropriately designed drive tray, maybe you could
do that; but Linux lives a lot in its HD and if you just swap HDs you are
likely to crash it. So I think you want to look at least at going down to
read-only mode (you see this during shutdown) before you swap drives; and
then, you have to update the Linux somehow concerning its new HD. This is
all the guessing I can do, on basis of what you said about your application.
If you are swapping a different HD than the one where Linux root lives, then
I think the application gets simpler.

I've got a Turtle Beach Daytona that has some strange troubles when running
in an SMP kernel. After some (random) amount of time, the thing locks up
(stops playing sound). The rest of the system is fine, though. When I run
the same tests under a single processor kernel, I don't encounter any such
errors.
I'm looking for something that people have hammered quite hard in an SMP
environment. I want something I can put in and forget about, for the most

I think I know how remote X Window operates, the X server on one's computer
serving up the screen and keyboard to client processes running on a remote
machine, but what happens when I'm using Netscape and load a page that wants
to play a sound? Do I need a sound server, too?

The no-value keys are the ones I use. I goes to show, there
are different strokes. I *love* the LCD display on my
laptop. It's crystal clear and even my tired old eyes can
see it clearly. I'd prefer 1280x1024 on my secondary
display (20"), but the lower resolution makes my LCD display
look weird.

The numeric keypad multiplies the problem with shift-lock
into the num-lock space.
The keyboard drawers at work are strange. In the new digs we
were allowed to cusomize our "ergonomics". The keyboard
drawer I picked for my main system has a riser for the mouse
that I thought I'd hate (so I added a mouse drawer beside
it). Actually I like both. The mouse riser sits above the
numeric keys and I rest my arm on the "mouse drawer".
My secondary system has a classical drawer with (in theory
with room for) a mouse. It's a good thing it's a secondart
system. The setup sucks.

Wouldn't that be a PC keyboard? I'd prefer the F-keys back
over where the *useless* numeric keypad is now. I guess
it's my 3270 training. ;-) Seriously, I get confused
between 2 and F2. I think '2' and position. I'd prefer the
'F' keys in an array.

I'll confirm that PCI-to-PCI bridges are transparent to the drivers.
I have a dual channel SCSI controller which also has an Ethernet port
using an Intel chip. In Linux, OpenBSD, and Windows, the standard
Intel driver works without any change.

Case design plays a major role in airflow. Instead of noisy fans
forcing air through a cramped case, a large, well designed case may
get by with fewer fans.
To increase the airflow, designers can use more fans, faster fans, or
bigger fans. More fans equals more noise. Faster fans means more
noise. Larger diameter fans move more air without more noise. How
much noise do large, slow ceiling fans make, and how much air do they
move?
Fans also make noise as the blades move past obstacles. The typical
way of keeping fingers out of fans by mounting them on a metal plate
with holes punched in it will greatly increase the amount of noise.
Even a small separation will drop the noise level. If you can, use
spacers and shrouds to get the blades away from the plate.
A fan controller that varies speed with temperature is another
approach. Costs more, but how much is peace and quiet worth?
Hot air rises. The most extreme solution I've seen, probably linked
from slashdot, was a tall chimney rising from the fan exit hole of the
power supply. Six feet of vertical PVC sewer pipe will provide quite
a draft just from convection. Flexible dryer vent hose would probably
work, but with more resistance to the flow. Conversely, the stupidest
thing that I've seen anyone do is put a fan in the top of a six foot
rack - blowing down!

Thanx to those who answered a previous post, but I am still having some
difficulty.
I recompiled the kernel with sound enabled and no-sound modules. I
configured Alsa with the following
./config --with-sequencer=yes --with-isapnp=yes --with-debug=full.
Both compiling the kernel and building Alsa went ok. Then I edited
/etc/modules.conf with the following
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=1
alias snd-card-0 snd-card-ens1371
options snd-card-interwave snd_index=0
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
Then I did the following: (Suggest by the ALSA Install guide and faq)
modprobe snd-card-ens1371
modprobe snd-pcm-oss
modprobe snd-mixer-oss
But still I have no sound.
A cat of /proc/modules:
snd-mixer-oss 4288 0 (autoclean)
snd-card-ens1371 2304 0 (autoclean)

Do you turn the sound on with alsamixer?
Note the default is sound is off with the alsa drivers.

I believe about the only difference between you an I, which I can see,
right now is that you compiled without the --with-oss=yes set on
./configure, and possibly enabled sound built into the kernel instead of
choosing sound support as a module.
I wound up finally with the alsa-driver-0.5.10b, alsa-lib-0.5.10b and
alsa-utils-0.5.10, and by linking my 2.4.3 kernel build directory as
/usr/src/linux, I got the drivers, libs and utils to all build. That is
on a RH 6.1 glibc21 system.
Alsa seems to not understand the new 2.4.x kernels module directory
structure and puts, if I remember correctly, the new drivers in a
/lib/modules/2.4.3/misc directory instead of in the
/lib/modules/2.4.3/kernel/drivers/sound directory. (or was that on
Peanut Linux w/2.2.19 kernel) don't quote me for sure on that last
sentence. You'll just have to play it by ear on your system.
Anyway, it will put an option in your ntsysv setup for starting alsa on
system startup also. Or at least it did on mine.
The following in my /etc/modules.conf:
alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-card-ens1371
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
options snd-card-ens1371
alias char-major-89 i2c-dev

options i2c-algo-bit bit_test=1
alias char-major-81 videodev

etc.
One other think, I did compile the kernel with the isapnp as a module.
With the above configuration in /etc/modules.conf sound seems to come up
when I need it and I've got stereo sound in Linux with my TV and gradio
tuner for the first time ever also.
Hope you can find something of value in the above mess.
G'luck.
