Which NFS block size (rsize, wsize) should I use for an MCA 3COM 3C523
ethernet card? With 8192 I'm getting lots of timeout errors. Maybe this is
why the driver is labeled experimental? I'm using Linux 2.2.9.

Hello,
I have an Epson Stylus Photo 700. I've tested it using an ASCII test
page and it worked okay. I then tried a test using PostScript and now my
printer keeps printing blank pages after the intial page with garbage on
the first line. Even after I remove the job from the queue, it still
continues to print. How do I configure this printer properly and how do
I remove the print job from the printer's memory? Usually, in Windows I
can easily cancel the job from the printer status monitor. Does this
mean that this printer is unsupported by Linux/Epson?
Cheers,
Brett

That should read "trying to load sound support as a

Do:
modprobe ppa
Then you can mount it normally.

Crossposted-To: comp.os.linux.setup
I now have the 2.2.9 kernel installed and running in my rh5.2 install,
smoother, faster IDE (UDMA33 works now) by 400% & all that.
But, I also have a an Adaptec aha1540 bus mastering (aka DMA) narrow
scsi-II card.
In its own bios, which is not installed since there aren't any Int 13
devices, the DMA is turned on, and set for about 5mhz/second.
I've recompiled the aha1542.c driver to add the 0x230, 0x234 addresses,
without which its not found on a TYAN S1590S board, with bios V1.16b
just installed.
There is a line in that code that appears to be the DMA switch, and is
originally set at {-1,-1}. I changed that to a {5,5} to correspond to
the cards own bios settings, and installed that module, but on the
reboot, the transfer speed is still 1.51 megs/second, just a wee, tiny,
scosh slow. :-\
It ought to be 4-5 megs a second, maybe more with some fine-tuning.
So, how *does* one go about making DMA work on this card and driver?
Cheers, Gene

Hi,
I'm having a bizzarre problem with my mouse in XWindows. I've installed SuSE
6.1 and I can only see my mouse cursor flitting around the top of the screen.
After I start the X Server and start KDE, I can't see the mouse at
all...although it's there and working. For example, I can move my mouse and
see the buttons highlight, I can right-click on my desktop and get the pop-up
menu, and I can select things. It's just like it should be except that I can't
see the mouse cursor at all!
I've tried different mouse settings to no avail. Any ideas?
Thanks,

Hello,
I've a problem with X11R6 (KDE) and a Daytona SiS6326 AGP graphic-card.
The screen isn't shown correctly.
Details:
I installed a Daytona SiS 6326 AGP card in my second PC.
Everything worked fine but as I couldn't find a suitable driver for this
card I choose the driver called "SiS6326".
When I started X11 (KDE) the screen was screwed, I couldn't see anything
right.
Well, I edited with vi my XF86Config-file (without knowledge about this
file) and I've re-commented an options-line "fast-vram".
Since then I've been able to see everything on my screen, but there're a lot
of drawing-errors like these:
- I cannot see the programe-bar sometimes
- I cannot read the letters of some programmes
(on my 1st machine with a Riva128 I can see them!)
- If I move a windows around, it redraws not correctly
- Sometimes my pointer changes into a white box
- Tree-view items (for example in the KDE-control center) are black
instead of white
but when I chose one of the objects inside they become normal for a
couple of seconds
Can somebody help me?

Subject: Re: Dual Celeron's and SMP Performance Problems
I have found this discussion interesting, in part because I have a dual Celeron
"workstation" (300As @450/100).
While I cannot claim complete/through understanding of all the issues raised I
re-iterate a summary:
Because of their small 128k L2 cache Celerons are *likely* to be a poor choice
for building fileservers in particular and when operating in a SMP situation
*may* perform particularly poorly compared to CPUs with larger L2 caches - even
if those caches operate at 1/2 clock speed (PII/PIII).
(*likely* and *may* have been emphasized because the arguments have been
theoretical and no benchmarks or real-world tests have been offered to support
the theory - how ever reasonable it may be)
This would be because the cache contents must be synchronized between CPUs over
a 100mhz or 66mhz bus, thus eliminating most of the potential benefits of the
Celeron's full-speed L2 and increasing the penalty for a cache miss.
If an application is not optimized for small cache size (i.e. 128k) it will
*likely* perform rather badly on a Celeron and perhaps worse on Celerons in SMP
configuration.
My personal experience with this particular system is that it performs rather
well - compared to what you ask? - well I had a K6 300 with 196MB RAM, built
this with one CPU and added a second. Some operations are 5x faster than they
were on the K6, the system is more responsive under multi-task situations than
with the single CPU, but it is by no means twice as fast.
Here is a quick and dirty comparison - not ideal as many factors besides CPU
enter in (OS differences, UDMA implementation, different background tasks
running, etc.) I ran each task separately, then started the PS filter and added
the other two -> all three at once. Time 1 = single task, time 2 = all tasks at
once; min:sec. Booted W98, defrag disks, run tasks, boot NT...

Premiere demo 4.2 run with a "speed test" from:
http://members.aol.com/simmike
File transfer - partition to partition, same IDE disk, 259MB
The results seem pretty clear cut - the second CPU helps quite a bit under
multi-tasking situations, and two of the tasks complete more quickly under W98
when run alone.
As for the topic of the thread - what about some server benchmarks?? Abit is
purported to have a dual socket 370/BX chipset board in the works - is it
possible some of the *potential* limitations of small L2 can be mitigated on the
motherboard?
Implications for Linux seem to be - design apps to minimize the impact of 128k
L2 to get the max benefit of Celerons (the C400 should be selling below $100
w/in 2 weeks...).
When I put this system together PII400s were running about $400ea. The premiere
movie build runs at about the speed of a PII 400 when run alone. The two
Celerons and converters cost less than $200. The $$ saved on the CPUs went into
RAM. By this fall or winter PIII 500s should be selling @ or below $200 I
think. CPUs are not holding their value very well, compared to other
components.

I have had the same thing.
I bought a new mouse so I had to change the mousedriver.
I did this with mouseconfig, but in Xwindows it was there but didn't work.
I tried and tried but it didn't work.
When I reinstalled Linux it DID work !
I guess I first had to delete the active mousedriver and then install the

So try finding out how to uninstall a mouse driver and install the right
