I have a PCI version of the creative labs AWE64 soundcard and I just
can't get it to work.
Does anybody have this type of card? and got it working in Linux?
Help would be greatly appreciated.

if you are at all interested in having a seperate system for linux, you
may want to consider a dec multia. it's not a screamer, but it is a very
competent system. video, sound, scsi, and networking are all built
straight onto the motherboard... prices range from 50 to 100 bucks.
obviously this doesn't include a moniter, keyboard, mouse, or hard
drive, but still, i'd say that's a nice deal.
that said, remember that it is an alpha, which is a 64-bit risc
processor, so it can't run 95/98... but it runs linux like a champ!

Hello,
When i installed my Red Hat version 5.1 on my laptop everything went OK. But
when i want to start pcmcia service by typing 'pcmcia start' it doesn't work.
It only works when i execute it by using 'sh pcmcia start' When i create a
file name DODO and change it to executable by typing 'chmod +x dodo', I can
only run it by typing 'sh dodo'. I would like to know what am i doing wrong.
In what way can i change 'sh pcmcia start' to 'pcmcia start'. I don't want to
execute sh all the time. Currently i'm running bash as my shell.
Thanks,
Martijn Joosen

Running Red Hat 5.2.
My card is listed but I cannot run X windows at any resolution or monitor

Hi Swaroop,
I brought my Lexmark printer 2050 for years and have also asked the same question

These two are performance features that depend very heavily on knowing what
the expected access pattern to the storage would look like.
I'll come to that in a moment...

Here's another approach, which I think offers much greater integrity with
acceptable performance:
First, let's dispose of this idea of using a RAID stripe width of only one
sector! The ideal stripe width is at least the size of the file system's
smallest allocation unit, which is pretty much guaranteed to be 4K or larger
(i.e. 8 sectors or more). Generally, a *lot* more! 64K seems a fairly
common width in commercial RAID 5 products.
Secondly, let's define an access pattern. For something like this, I am
presuming that the disk's purpose is as a fast archive, with lots of reads,
virtually no updates, and bursts of append-type writes. I also assume that
it would be OK to require disk intensive "cleaning" processes as and when
required (think something like Windows' Defrag).
Now, for this to make much sense, we need a filesystem that is either aware
of the way in which we're handling the disk, OR a naive filesystem, such as
those thoughtfully provided by Microsoft for the desktop! It would also be
nice enough to perform write-type operations (writes or rewrites/updates) in
large-ish chunks.
Divide the disk into, say, 8 equal sized concentric zones, call 'em D0
through D7. Initialize each sector to logical zeroes. When data is to be
written, the controller examines a non-volatile "High Water Mark", which is
initially set to be the zone size, in sectors.
If the sector address of the first block to be written is greater than or
equal to the HWM, then the controller first reads the old data, writes the
new data, and creates parity by XORing the old and the new data. It then
increments the HWM by the number of sectors written, and then adds the zone
size to the sector address that was just written. The drive then seeks to
that new sector address (which will be in the adjacent zone, Dn+1), and
writes the XOR of the old data and the new data (in classic RMW fashion).
On the other hand, if the address of the block to be written is less than
the HWM, then this I/O is in fact an update, which we can do, but which will
be slow. In this case, we do a classic RAID-style RMW operation, locating
the parity data in the zone following the current HWM.
OK, so let's look at the performance:
Normal-mode Reads: *exactly* the same as without any protection.
Degraded-mode Reads: Horrible. With 8 zones, 7X the regular read time.
But still infinately better than not being able to read at all!
Update-type Writes (rewrites): Seek to data, wait for rotational delay,
read data, rotational delay, write data, seek to parity, rotate, read,
rotate, write. Obviously, this looks (worst case) like 4X the uprotected
device's time, but with reasonable I/O sizes from the filesystem the
rotational delay between each read and write pair can be minimized, leading
to a best case of 2X the uprotected time + 2X the data transfer time.
Append-type Writes: Seek to data, rotate, read, rotate, write, seek to
parity, write. Worst case, 3X. Best case, 2X plus 1X transfer time.
[ Or you could dispense with the special handling of the Append writes, lose
the non-volatile HWM, permanently allocate one zone as the parity zone, and
treat every write as an update. Simpler, but slower. ]
Now, I realize that this could well be worse *write* performance than
interleaving the parity, but there is the benefit that the (normal mode)
read performance is unimpaired... and given a fairly normal access pattern,
that's rather important (read a bunch of executables and support files,
churn around on that in memory, then spit out a small result file). It has
another benefit, in that the disk could be used read-only by something that
lacked knowledge of the additional parity (assuming no defects, of course).
And this approach certainly offers greater protection against defects than
an interleaved parity scheme...

It is probably due to the Sis 6326. Lots of people have been
reporting problems with configuring X for this card. I still haven't
managed it myself. From the messages I read it it obvious that the
options below have to be added to the device(?) section of XF86Config.
Option "no_accel"
Option "no_BitBlt"
Option "sw_cursor"
Good luck.

Two pieces of info for you,
a) RH 5.2, by default, uses a customized fvwm95 environment (M4 scripts)
b) In a Un*x environment, the graphical interface is actually comprised of
two pieces, the graphics subsystem (Xwindows), and the visible "feel"
(windows manager). You are most likely using XFree86 as your Xwindows
subsystem. KDE, fvwm95, WindowMaker, etc. are all varieties of window
managers, which give you the "feel" of your GUI.
Good Luck and enjoy!

Date: Thu, 18 Feb 1999 23:28:24 -0500
I am using a Synaptics touchpad and like that feature (mine is not on my
keyboard however, I can see the problem there). I also looked at that
driver. What I found out (after also looking at Synaptics documentation
and touchpad command acrobat file) was that newer touchpads have fewer
of the features which that driver tries to control.
What I did was to modify GPM to support the Synaptics Touchpad (these
changes have been submitted for integration and will be in release
1.17-5 I guess). My modifications allow configuring the touchpad for
several features which I was looking for:
the synaptics edge motion even when you aren't dragging
pressure sensitive speed when using edge motion
...
If you feel comfortable with rebuilding GPM and have the 1.14 sources, I
have the patches which I submitted and can email them to you if you drop
me a line. Or you can check the GPM site and wait for 1.17-5 (I don't
know when that will be out) at ftp.prosa.it:/pub/gpm. If you try my
changes to GPM let me know how they work for you.
