Dear Sebastian
Thanks.
Does RH, SuSE or any other distribution come with the kernel
has all the things compiled ? How can I know how many things
are included in kernel ?
I've no idea on the kernel compiling.
Can you give some more advice beside your included link.

Hello,
Since more weeks, I try to resolve this probléme!
When I want to connect my fai, with kppp, after the négociation, kppp
hang up!( i try an other fai too)
With a lot of persons in the NG, we have to configure the ppp option file,
but it's the same probléme!
I think it's a problem of modem config! because sometime it's OK! often when
the speed connection is < at 32000 bps, no problem.
If speed connection is > 32000, modem hangup!
What do you think about it???
For info, I use suse6.4, whit an internal lucent winmodem+ ltmodem module,

Yes - when compiling PCI128 support (ES1372) directly to the kernel,
there's no need to run sndconfig. It should work out-of-the-box.

Hi there!
The performance of graphical segment of hardware is limited by the
weakest link.
If what is the limit in your case is the monitor, which cannot accept
information faster than 800x600 pixels refreshed X times a second, then
you will get the same performance from both cards as both of them are
capable of more than that.
And it is not dependent on the OS, just that in Linux you can destroy
the monitor by instructing the card to put it in gallop.
But this is for gamers and we are serious computer users;-)))

No, because /dev/dsp0 does not exist. I checked on my older computer
which has a different sound card (which has always worked fine) and it
doesn't have /dev/dsp0 either. Is /dev/dsp0 something that this
particular chip uses? If so, can you tell me the correct mknod (i.e.
what should major and minor be)?
I *do* have /dev/dsp and /dev/dsp1:
crw------- 1 david sys 14, 3 Apr 17 1999 /dev/dsp
crw------- 1 david sys 14, 19 Apr 17 1999 /dev/dsp1
I tried the /dev/urandom bit with both of them and just got silence.
If it helps, my syslog shows what sound like positive messages regarding
the es1371 driver, but the Sound HOWTO implies that I should see "Sound
initialization started" or something to that effect, which I do not see:

Here's another clue. Last posting prompted me to take a look at the
source (es1371.c). The last revision comment says:
* 05.01.2000 0.22 Should now work with rev7 boards; patch by
* Eric Lemar, <email address deleted>
My syslog messages from the driver clearly indicate that I have rev8. So
maybe I just have to wait for Eric Lemar or someone else to get the
driver to support rev8?

Hi,
I have changed my hardware and now use 3dfx Voodoo 5 5500.
Unfortunately, Linux now fails to start KDE but I am at a login prompt.
I have tried running YAST/SAX but it reports 'unknown chipset'.
Under Linux, all I need is basic 2D functionality at 1024x768 16bit
75Hz refresh. Is there a driver/work-around available?
Thanks

Generally it wouldn't make any difference, *but* the more video memory you
have free the more space there is for caching pixmaps and stuff, which
improves the performance of 2D work.
It has more impact on 3D performance, where generally you need enough ram
for the actual display, 2x as much again for double buffering and some more
to cache textures.
But for general desktop work, if the only difference is amount VRAM you're
unlikely to notice any difference.

Mine looks roughly the same as yours (you only have a newer card).
You would maybe be on the safer side if you didn't have es1370
included as you don't have that card but I don't think that's what
causes the problems.
What do you do when you try to get sound out of your machine? What
program do you use? Do you use a mixer to check the levels? The
driver doesn't mute the channels like Alsa does but maybe they are
lower than you are used to. Also, is there maybe a program (daemon?)
blocking /dev/dsp*?
How is your cabeling between the card and the speakers? Do you know
that it works?
