Subject: Why Has My PC Card Modem Quit Working?
Date: Mon, 26 Jul 1999 13:16:45 -0500
Hello, everyone.
I have a UMAX 316T 300 mHz AMD K6-2 notebook running Red Hat 5.2 with
the 2.0.36 kernel. All of a sudden, my PC Card modem has quit
working-again. Previously when this happened, I could get it going once
more by either resetting the permissions for it with chmod or
reconfiguring its port with setserial. (By the way, what causes these
to ever change once they've been set?) Neither has worked this time.
Any ideas out there? Does anything like this ever happen to the rest of
you?
Until I can find a solution, these messages will come to you courtesy of
my modest contribution to the obscenely huge pile of filthy lucre heaped
upon the altar of Bill Gates...

I don't have any problems, I don't have a CD changer installed. I am
asking before I go out and purchase one, to see if anyone has any
recommendations or negative feedback about the products.

No, if you compile for a single-processor system without -D__SMP__, the
spin_lock_irqsave and spin_lock_irqrestore primitives turn into
save_flags();cli() and restore_flags(). In other words, they become the usual
mechanisms for critical region in a UP kernel.
And spin_lock() (the non-IRQ version) simply becomes
do { } while (0)
in other words, a no-operation. That's because there is nothing to do; because
there is only one processor, so there are no other processors to keep out
of the critical region, and the semantics of spin_lock() allow interrupts,
so cli() is not needed. Have a look at the asm/spinlock.h header to
see how it handles conditional compilation on __SMP__.
So I wouldn't worry about losing performance from spin_lock() or
spin_lock_irqsave() on a single processor system. :)
By the way, I always use spin_lock_irqsave(). I never use the variants that do
not disable interrupts. This way, a given processor's time in the critical
region is minimized, and the atomicity of the code is guaranteed against all
possibilities: other processors as well as interrupts, bottom-half callbacks
etc.
> 4. [kernel semaphore]: ?
A semaphore can only be waited on by a process. Semaphores are useful for
synchronization between tasks, or between tasks and interrupt (in which case
the interrupt signals only, and only the task waits). A semaphore is useful if
process must be delayed for some potentially lengthy period of time until
something happens, during which time it's desirable to run other processes.
It's not suitable for brief critical regions.

I think if you really want the power of xeon, you'll have to get used to
the
fan noise. Since xeon processor machines usually come with high
performance
hard drives, which generates a lot of heat. Without proper cooling,
these components won't last long, neither will the processors. I
personally don't
know of any place that sells "Quiet xeon machines". At least it'll be
hard
to find.
You can probably find quiet hard drives to help out.

If you are using the default gnome term then your $TERM should be set to
xterm. This will make your editing sessions work as they should.

DMA is not UDMA. If your EIDE drives are UDMA capable, 'dmesg' will show
this, but it doesn't mean they are actually configured as UDMA. Use 'hdparm'
to force UDMA operation and see what happens. Execute a write test of a very
large file and check for kernel messages. The problem with the UDMA driver
for 2.2.9 is that it succeeds for read operations, but fails on writes.
Several people have mistakenly posted that UDMA is successful under 2.2.9,
but they only ran the hdparm read test and did no testing of write. What
happens on this failure is that the driver gets kicked into PIO mode to
complete the write operation. Depending on what the user is doing they may
not even notice this has happened until they look at the kernel log file.
It is possible that this was fixed in 2.3.5, but I doubt it. I think you're
just getting DMA (which I do agree is much better than PIO).

Has anyone tried recording an audio CD with the -dao (disk at once)
option? The inference from the man page is that as opposed to
"track at once" (cdrecord-1.6) the -dao option will eliminate the
annoying 2 second gaps between tracks. I compiled cdrecord-1.8a23
under 2.2.9 last night, but it was too late to try any burning.
If anyone has already tried this please let me know. I already

Does anybody know where on the net you can get a pre-isntalled Linux
box (intel, Redhat 6) for about $250? I plan on using this as a Web and
mail server. I heard of a consumer box that is being pushed by Prodigy

Subject: Guru advice need for parallel LS120 re-install
Date: Mon, 26 Jul 1999 19:13:22 GMT
Knocking my head against the wall so often that I'm developing a bald
spot.
Previously I've had a parallel Imation LS120 drive running on linux
kernel 2.0.36. Installed paride, epat, pf as modules with everything
running smoothly. Ok, so I want to install 2.2.10, KDE1.1.1 and figure
that this is a great time to tweak and rebuild my 2.0.36 kernel for
laughs. I make and install a new kernel and reboot, login and oops no
superdisk anymore. I get a "init_module: Device or resource busy" when
I 'insmod pf'. OK, so instead of reverting to the saved kernel I go and
build another with no PLIP, no parallel printer support and parallel
IDE support, epat and pf into the kernel. Same again. Did I save my
original kernel? Of course not, that would have been the intelligent
thing to do. I cat /proc/devices which doesn't list /dev/pf as a block
device, not good. I cat /proc/ioports and don't see my parallel port
occupied, so who's busy?
5 rebuilds of 2.0.36 later has been a waste of cpu cycles. Obviously
I've got some contention here that I'm overlooking.
What have I missed?
I've configured ( and reconfigured ) the following:
o enabled parallel IDE support and extended device parallel IDE support
in the kernel
o enabled parallel IDE support for disks, tapes, floppy, cdroms, sewing
machines...
o verified that MoBo likes EPP for parallel port 0x378, IRQ7
o disabled any device that tries to get within 100 feet of the parallel
port ( parallel printer support, PLIP, etc. )
I now know the meaning of "If it ain't broke, don't fix it",

Subject: TB Fiji & Digital I/O success
Date: Sun, 25 Jul 1999 20:14:42 -0600
This isn't particularly ground-breaking, but questions on the TB Fiji
and Pinnacle cards come up every couple months, so I thought this was
worth posting.
I've been preparing to record my vinyl collection onto CD, and finally
have succeeded in recording my first album. I'm using the Fiji w/ spdif
I/O option, and in the process of setting this up I've verified that
both the digital input and digital output work as expected. I'm
recording using an external Symetrix 620 A/D, connected to the Fiji via
the digital input. Aside from having to hack up a version of mix2000 to
allow setting the input source to Digital1, and some wierdness with
getting it to actually kick in (requires switching back and forth from
line to digital a couple times before it finally 'takes') it works
flawlessly.
As an exercise, I also verified that the digital out worked - I hooked
an old AudioAlchemy D/A to the digital out, and that worked (although I
now realize that I forgot to check whether the mixer output level
affected the digital output. oh, well). The quality of the Fiji analog
output is better than the external DAC, so I don't see much point in
using the digital out unless you're transfering to another digital
medium or are doing further signal processing via dsp with it.
I haven't yet done a comparison between the external A/D and the Fiji
A/D. I wouldn't be the slightest bit surprised if the Fiji was as good,
but the 620 has a noise-shaped/dithered 16 bit output that gives me a
warm fuzzy feeling that I'm doing the best I can for my vinyl (in
reality, the noise floor is probably so high that it doesn't mak a bit
of difference, but there's the analog superstition for you).
Overall, I have to say that with buy.com blowing the Fiji w/ditial i/o
out for under $200, anybody looking for a semi-pro and/or home studio
recording setup should jump on this guy - it's performed extremely well.
I'll also put in a plug for 'gramofile' - a tool aimed at recording
analog (record or tap) collections onto CD - it 'automatically' splits a
single file up into multiple tracks (does pretty well, but isn't
perfect), and has a set of filters to help in scratch/pop removal etc.
It's still slightly rough, but it gets the job done. Written by Anne
Bezemer (hope I got that right - a student in NL) and available at

Hi,
I've SOHO (small office/home office) packed full of six computers right
now. It's a space nightmare. One machine is acting as a bastion firewall
to a dedicated line. I'd like to set up two more machines, one for an
outer firewall (to create a DMZ) and one as a private web server inside
the DMZ. (I'd like to give access to some internal info while at client
sites -- without opening up the bastion at all.) I'm running Linux on
all machines save a couple which dual boot to Windows NT/98.
I've hunted for web pages for small computers like the Cobalt Qube and
the NetWinder, but have not found anything. I presume they've gone out
of business?
Are there other tiny Linux-capable computers with horsepower like these
two? Space is at a premium, otherwise we'd just toss in a couple of
normal machines.
Thanks for your suggestions!

Based on what you want to use this machine for, IDE will be fine for
you. I have an SMP server on which I'm running Oracle and RAID. I hit
the machine hard from time to time. SCSI works wonders for that machine.
All my other computers are IDE.

I've had good luck with AOC monitors lately (17" Spectrum 7Glr/A). I
remember when AOC first came out and they were monitors to run away from
in my experience. It took a fast-talking salesman that I trust to get me
to try AOC again. Though older, I still love my 19" Princeton EO90.
I don't know whether cheap monitors are still different from their
pricier cousins. There used to be a big difference.
