I have an HP720c that's working pretty well. Check out my Linux
page for the urls to get good info on making it work. the link
is;

The newer HP DJs use a proprietary HP protocol called PPA. A
dude named Tim Norman reverse engineered PPA and worte some code
and scripts to let us use them under Linux. There's no
color-printing yet but Tim posted that he's working on it.

There's a pretty good list available on AMD's site. I pulled the
list and decided on an FIC 2013. It works great! Just make sure
you get the right kind of memory (bus speed compat).

Subject: History of USB developers switchover
Date: 09 Jun 1999 17:04:11 -0700
Just curious. I'd like to know a brief history of the recent
change in USB developement. I'm wondering if the old project
leader (and his team?) spent several years working on the thing
only to get tossed overboard by Linus and friends because Linus
had a few, presumably better ideas. Anybody know what the
situation was? I suspect many people would be discouraged from
participation after seeing someone else's work get tossed out,
even in the cause of a better kernel.
I just started reading the very nice "Kernel Traffic" news and
haven't seen much evidence of heavy-handedness, but having read
the Kernel FAQ related to the kernel mailing list, I know there
are a few arrogant and nasty people involved in the kernel work.
Apparently not the key leaders, thankfully.

i have a couple of pentiumpro-200 systems and they are still plenty
fast for me.
it depends on what you are doing. the latest processors are very fast
and components such as memory and disk have not kept pace. many tasks
are i/o bound and will not benefit from a faster cpu. if you are
trying to save money then go for the celeron. you can even try
picking up an old ppro system at a computer show or garage sale.
if you *really* *need* raw cpu performance, then alpha might be a good
choice - especially for floating point. they are a bit more expensive
than the intel offering however.
most people would do better by taking the money saved on the cheaper
processor and buying more ram. get at least 64M of ram.
make sure you avoid the dread winmodem.

I accidentially deleted /dev/ttyS0 and /dev/ttyS1. After that, I used
/dev/MAKEDEV to build it again, but then ttyS0 and ttyS1 didn't work
anymore. When I tried to do "ls -l > /dev/ttyS0", it said "read/write

the problem is, the LCD matrix is 800x600 dots. so when displaying
640x480,
there's a kind of aliasing. that's "perfectly normal" in the sense you
can't
solve the problem, except by trying 800x600.
I spotted the same problem on variouses compaq laptops, in MS-DOS the
text is
real ugly (exactly what you describe).
to get 800x600 to work , try hand-editing /etc/XF86Config (or wherever
it
resides). that *may* work.

This machine will be a dedicated Linux box running the latest 2.2

I've checked these parts and they seem to be pretty good, however if

The unresolved symbols problem usually means two things: you are using a
2.0.X kernel and you don't have the modular sound patch applied.
Unless you have strong reasons to stick with 2.0, I'd suggest you move
to a 2.2 kernel (I'm using 2.2.9 and it's very stable).
: I am using kernel 2.2.5 that I downloaded from ftp.si.kernel.org

Well, you should be using modutils 2.1.121 or better, but that aside, you
should have the following set for kernel config:
CONFIG_SOUND=m
Don't pick any of the drivers! Make sure you do a "make dep; make clean"
before building things. You might also want to remove your old
/lib/modules/2.2.5 modules before installing the new ones. Once you've
installed the new modules & kernel, copy sblive.o-2.2.5 to
/lib/modules/2.2.5/misc/sblive.o
If you don't have the /dev device files already you can create them by doing:
cd /dev ; ./MAKEDEV audio
Put something like the following into your /etc/modules.conf:
alias char-major-14 sblive
alias sound sblive
post-remove sblive rmmod soundcore
install sblive insmod -f sblive
Reboot and then you can do:
modprobe sblive

I can't seem to figure out how to apply the DMA patch for my ALi chipset.
I got the patch from vanderbilt, but I have no idea how to apply it. My

that doesn't work. Can ahyone who has done this point me in the right

Hello everybody,
I have a Video Highway Xtreme tv-board in my computer and i can't get
it to work. What did i do:
I compiled the kernel without support for video, i downloaded the
newest bttv-drivers and installed them. This is what "dmesg" shows me
when i typed the following commands:
insmod videodev
insmod i2c verbose=1 scan=1 i2c_debug=0
insmod tuner debug=0 type=5
insmod bttv radio=0 card=16
Linux video capture interface: v0.01 ALPHA
i2c: initialized (i2c bus scan enabled)
i2c: driver registered: tuner
bttv0: Brooktree Bt849 (rev 18) bus: 0, devfn: 128, irq: 12, memory:
0xe7020000.
bttv: 1 Bt8xx card(s) found.
bttv0: model: BT849(Aimslab VHX)

i2c: scanning bus bt848-0: found device at addr=0xc0
i2c: device attached: tuner (addr=0xc0, bus=bt848-0, driver=tuner)
When i start Kwintv i can get a picture when i select NTSC (here in
the Netherlands we use PAL) but it doesn't look wel. When i select PAL
i can't get a picture.
I also tried Xawtv. The installation goes well but when i start the
program i got the next error-message: "Can't execute program"
Can anybody help me with this problem.
Thanks in advance

*i* think it's ok. with . last, you won't have normal system commands
getting shadowed by something in your current directory.
if you are alone or sharing the machine/filesystem with trusted people
(like at home or work as opposed to at a large university) then i'd
say go ahead and put . last. i don't do it for root, however.
life is a risk. you are 100% certain to die at some point. turning
the machine on in the first place is a security risk. however, the
computer needs power to be useful. do what feels comfortable. make
and maintain backups.

Oh yeah, you COULD, if you wanted to, rebuild the initial ramdisk image with the
initio driver
as a module on the ramdisk image. This would work assuming lilo loads the ramdisk
image
(or the kernel does it via the INT13 interface). I'm pretty sure that's how RedHat
supports quite
a few drivers (i.e. in the ramdisk, not the kernel), so this would be another way to
go.
However, I find building a ramdisk image to be more painful than rebuilding the
kernel...

This ether card uses the via-rhine driver. I use one of these

you have compiled the via-rhine driver into the kernel or loaded as a
module.
If you need help with modules, I'm no expert. What little I know

I had the same thing with a cyrix 166+ cpu. starting X via kdm was ok.
then
I logged in, with afterstep, and during afterstep startup, X crashed. if
I
started an xterm instead, and then started afterstep, it ran fine.
upgrading
X did not help. not launching asmail did work. when I switched to a
166MMX
CPU, asmail worked again. dang.

maybe, maybe not. more generally, it means "hardware problem,
somewhere!"
and it arises generally while compiling the kernel (because it exercises
memory, cpu and I/O and lasts quite a long time on most boxes).
btw, how can one be sure his memory is not faulty? testers are dumb
(heard
many verified stories about changing "good" non certified RAM to
certified
one, and it worked).

try it anyway, it improves many aspects of SMP.

that would cost you a lot of money, for sure.
if you really *damn fast* I/O, go for UW disks and use raid (striping).
they leave IDE disks far behind.
real life example : while copying 200 megs from IDE to IDE, our server
feels quite slow. you don't even notice while copying from SCSI to SCSI,
and it also runs quicker.
IDE may be cheap, but for the purist who wants raw power, get SCSI.
also, problem of raid 5 is that it's very cpu greedy. without a
specialized controller, don't think about exceeding 10 to 20 mbytes/sec.
correct me if I'm wrong about this last point.
