Hi,=20
my new Matrox G450DH crashes when I try to start X 4.0.2. What is the=20
trick in the XF86Config? It's not only the Option sw_cursor in DEVICE.

Hi,
Does anyone have any experience using this motherboard with linux? I'm
experiencing strange, random shutdown problems that i can't replicate
installing w2k on the same machine. I already tried all advices found on the
web.
The machine is so configured:
dual PIII 800Mhz
mb Super micro 370DL3
SCSI controller AIC7892b
2x Quantum Atlas 18Gb
EIDE cdrom
I tried the following distros
mdk 7.2
rh 62.
suse 7.0
slackware 7.0
Thanks in advance

Thanks... except I am particularly concerned with the new i82550 chipset -
i82557 is definitely documented as being supported.
I read somewhere that the 82550 is basically the same as an 82559, but can
anyone confirm that it will work as such?

Did you mean 20GB? Per night? That implies values of "low cost" with
which I am not familiar.

Just about any SCSI tape drive will be supported out of the box, and as
easy (or not) to install as any other SCSI device.
We just got a Sony AIT-1 (SDX-300C) drive for our archival backups
(nightlies are done on an older Exabyte 8505XL). The AIT has 35GB native
capacity on tapes which cost about $70 (sorry, I don't have the francs
or euros conversions handy). The drive itself was $1700. Again,
it's not exactly low cost, but it *is* much less expensive than a DLT
solution of similar capacity.
As for software, we use amanda (info at www.amanda.org), which is *very*
nice. Amanda uses standard backup tools (filesystem native dump/restore
or GNU tar) and puts a *very* smart front end on them. It takes a bit
to figure it out and set it up, but once you do you'll find it's well worth
the effort.
Good luck. And remember, no one cares if you can backup the data. They
only care if you can recover it. Test, test, test.

During the linux boot.. BIOS sees it just fine, I can go into the DPT
bios and see all the drive specs, etc.. No hardware setup problems..
When the i2o driver tries to initialize, it can't see the raid.. I can
get 2G with no raid, or 960M (or less) WITH the raid, so I'm positive
it's a conflict.. The hardware is set up fine, because it works under
lower ram conditions.. There's 10 18G drives that show up in the os as
1 giant ~140G drive.. It's all HW raid, so the os doesn't even know the
difference.. It just thinks there's one big scsi drive there.. When I
put the
append="mem=2048M"
(or anything higher than 960) line in lilo.conf and run lilo, I get a non
descriptive 'i2o init failure' msg, then since there's no drive/fs's, I
get the 'fix your fs's' prompt and it stops the rest of the startup
scripts & dumps me to the prompt..
I've been looking around, and found stuff about old linux versions and a
960M limit on ram.. I wonder if this driver was made before the limit
was broken, so the driver assumes that 960M would be a good place to put
itself in ram, then 2G of ram comes along and blows it up.. I dunno..

If you want to get really low cost, you could try the
Seagate STT20000A, which is an IDE/ATAPI tape drive.
The tapes are TR-5 and hold 10GB raw, up to 20GB compressed.
The drive is about $350.
We use one here on our server and it is recognized and used
with no problems on Linux. You only need to be sure that
ide-tape is enabled in the kernel.
If you can afford more, then you might look at
SCSI drives which will have higher capacity.

None :-) You need a Matrox supplied driver (www.matrox.com, dig
yourself to the graphics cards / driver section. Now this should work
painlessly for plain X ; if you want 3D accelerated GL and the like
(DRI) this may be less joyful and may involve compiling your own

Well, mt and tar did just fine at first. Then I installed
BRU. It, too, is fine with my Seagate unit. Perhaps it's
the HP drive or your kernel that's causing problems. For
the record, I've used kernels 2.2.12, .16, .17, and .18 all
with no troubles. I've done plenty of backups and a
handfull of restores (including one complete backup,
repartition, restore cycle) with no troubles whatsoever.

http://www.3Ware.com/news/ataraid.shtml is data Jan 31 2001,
this is where they announce RAID5 support. The data sheet

Yes of course that's a setting. in /etc/inittab is an entry what to do
in single user mode. SuSE's default entry is /bin/login. Others
(Mandrake) may have a "real" entry wich even restarts "/bin/sh" on
logout.
At boot prompt: linux init=/bin/sh
could help anyway.....

I'm not sure about the 2.4 kernel, but the 2.2 kernel has 3 different
drivers for those SCSI cards:
NCR53c7,8xx, NCR53C8XX and SYM53C8XX
Maybe it would help to try another driver?

If your raid disk doesn't give better performance than a single disk
something seems to be wrong.
As the raid disk doesn't use more CPU than the single disk I suppose
that you have no redundancy? Striping with two disks should in theory
give up to twice the performance, are you using linear mode instead?
What does your mdtab look like? How big is the cache on your disks?
Maybe you could tune the chunk size to make better use of the cache?
However, are you using hdparm as a benchmark? This program is supposed
to test IDE disks. I'm not sure how it would react on a raid disk. Maybe
it would be better to do benchmarks like:
time dd if=/dev/zero of=/path/to/test_file bs=1024k count=100
time dd if=/path/to/test_file of=/dev/null
Please note that this kind of benchmarks might give different results
depending on how filled the disk is.

The first question in the ALSA FAQ:
Q: Driver is installed and sucessfully loaded in kernel, but it doesn't
produce any sound. What's wrong?
A: You should raise volume for mixer channels and/or unmute mixer
channels. Look for alsa-utils package at http://alsa.jcu.cz where
are native mixers.

I would suggest xemacs and gcc together with make. You will probably
have to recompile gcc from source yourself to get yourself a
cross-compiler.
I have no experience from MPC860, if it is a complete system with
keyboard, mouse and graphics capable of running X it might be a good
idea to use this for development. Then you will not need a cross
compiler and you will be able to run a nice debugger like ddd.
Even if the system isn't capable of running an X server you might be
able to log in remotely from another Linux machine if it has a network
interface.
