Hi,
Well , I just want to know is there any project to support AMR devices in
Linux or may be developing AMR library .
If I want to develop a AMR device driver what should I study ? Do I have to
study the AMR architecture and specification .

Reply-To: [EMAIL PROTECTED]
At my place of employment, we have an external HP Surestore DLT1 drive
that has recently started acting up. Symptoms include:
1--made a large backup, and tar -cv indicated it was writing everything
correctly. However, it exited with "/dev/st0: Cannot close:
Input/output error." The tape was unreadable.
2--The drive can read tapes just fine, but refuses to write them at all
now. Attempts to use tar -c fail, with a SCSI error ending in "Sense
key: Data Protect". Same thing if I try "mt erase". The position of
the write-protect tab on the tape itself makes no difference, the same
errors occur whether I am doing this as root or as a normal user with
appropriate group rights to /dev/[n]st0, and the same error occurs with
two different tapes.
3--When the tape is first inserted, "mt status" returns reasonably
normal values. Some indeterminate time after that, it will report that
the WR_PROT bit is set.
4--"mt status" reports that the tape has density code 0x1a, "unknown to
this version of mt." I'm guessing this is normal.
5--The TapeWare or whatever software that HP shipped with the drive is
unusable; it's only for x86 and this is an Alpha system.
Output from "cat /proc/scsi/scsi ":
Host: scsi0 Channel: 00 Id: 05 Lun: 00
Vendor: BNCHMARK Model: DLT1 Rev: 3618
Type: Sequential-Access ANSI SCSI revision: 02
Output from "cat /proc/pci ":
Bus 0, device 6, function 0:
SCSI storage controller: NCR 53c875 (rev 4).
Medium devsel. IRQ 16. Master Capable. No bursts.
The distro is RedHat 7.0 (not my decision!) running kernel 2.2.17, the
architecture is DEC Alpha EV56. The 53c875 is partially flaky; I blame
this on the fact we didn't have a goat and I had to use my own blood
during installation. I don't know if this is a hardware problem or not,
and I can't remove the tape drive and hook it to another machine for
testing until about 9AM 3/14/01 EST anyway, but if anyone has ever seen
a similar problem....
Please post to the NG, I seem to check this group more often than my
maildrop. Thanks in advance for whatever help anyone can give.

Hi all:
I'm looking for a diagnostics utils on Linux.
Where can I find programs or sources or related information?
The program can do hardware diagnostics, e.g. Random read test,
Sequential read test on disks, Dial tone and loopback test on Modem, etc.
Thanks in advance.

...if you want to compile a custom kernel at all, what less and less
people do nowadays.
But then, this has *not* changed since 1.2 or so (SCNR on this one).
My recommendation is to decide on building SCSI cdrom _and_ SCSI
generic support as modules each - that way, you can load the "sr_mod"
when mounting a CD, and the "sg" when burning, and unload each when
not needed.
One word more, please, to SCSI hard disk support : I'd recommend to
compile this fixed into the kernel (if the core SCSI support is
fixed also, of course) - as in my experience, there still might be
some trouble with adding the partition table(s) after boot time -
even though it shouldn't nowadays.

The cheapest way to investigate 4 processor systems is to pick up an
old SPARCstation 20 with a pair of dual processor cards. With the new
Sun Blade 100 starting at $1000, prices on the older systems should be
coming down. With Solaris licensing now free for systems of this
size, you'd also have the chance to compare Linux and Solaris SMP
performance. Linux on non-x86 platforms may require more effort,
although Red Hat 6.2 installed on my ss10 like a dream. If the prices
come down enough, maybe I'll be playing with SMP...
Single processor x86 systems deliver good price/performance. Dual
Intels do OK, too. But everything I've read says that with multiple
Intel CPU's, the prices rise faster than the performance.

The $20-but-free-after-rebate D-Link camera from Circuit City works, but
the image is truly crappy and you only get that if you shine a 100-watt
spotlight on your face.

Hi everyone,
I have a Creative decoder card (DXR2) and I can play DVDs/VCDs/MPGs on my TV
through Win2k with no problem. But now I want to take out the card and put
it in my P166 box (which is closer to my bigger TV).
Would it be possible to have the decoder card working along with the tv-out

Date: Wed, 14 Mar 2001 06:32:34 GMT
I'm thinking about getting either a Palm or Visor, and my initial
investigations have left me with a few questions:
Are there any web sites or other resources that deal specifically with
using Palm/Visor in a Linux environment?
I like the Palms due to their upgradable OS, and have seen info on
software for Windows and Mac to do this to the units. How do you do this
from a Linux machine?
I'd be interested in general opinions to the usefulness of Palm/Visor in a
Linux environment. And why one over the other.
Thank you for any info you can provide.

It's an Intel specification, so I'd start at http://developer.intel.com.
I actually tried to chase down the exact URL for you when I read your first
post a couple of days ago, but I got into an infinite loop following links
on their AC97 page (AMR is related to AC97). This page gets close:
http://developer.intel.com/ial/scalableplatforms/audio/
They talk about CNR, the "communications and network riser". My
interpretation of the information there is that CNR is a more general
specification, of which AMR happens to be one subset. If that is true,
then this page might be of help:
http://developer.intel.com/technology/cnr/index.htm
Good luck.

the question is, if we could put two haupauge wintv cards in the pc.
first, we need to know, if wintv two wintv-cards run in one pc.
second, does linux bttv kernel driver support having two wintv-cards?
or can somebody recommend a (cheap) frame grabber card supporting two

It means "Audio Modem Riser", which is a way to implement a modem and/or
soundcard without going through the system bus.

Not really.

Not that I know of. You might check freshmeat (http://freshmeat.net/)
for software, though.

Crossposted-To: comp.os.linux.networking
Date: Wed, 14 Mar 2001 08:12:18 GMT
I just recently installed SuSE 7.1 and am using their supplied 2.4.0
kernel. Their graphical admin tool YaST2 correctly identified the National
Semiconductor 83815 chip but I couldn't find a suitable driver in the list
of drivers that were listed. I first went over to the Netgear website and
found a driver but sadly it's compiled for an older 2.2.x kernel. I
downloaded the source of Netgears driver but I was unable to compile the
source against my 2.4.0 kernel.
My next attempt was to go over to the Linux Network driver page at:
http://www.scyld.com and found that the driver for the FA311 was named
"netsemi". I added my own "alias eth0 natsemi" to my /etc/modules.conf file
and I finally had a working networked card. SuSE 7.1 shipped with a working
"netsemi" driver for their 2.4.0 kernel but I also tried to compile my own
version of the driver. I was unsuccessful as I didn't have certain header
files that the driver wanted. This is a new experience for me as I ususally
compile my own kernels and only include the stuff I need. Since I can't
compile the "netsemi" driver I guess I'm going to have to stick to using
SuSE's supplied kernel for the time being.
I have no complaints about the performance of the FA311.

I am using the Ricoh MP9120A with RedHat 7.0 (kernel 2.2.16). As SUSE
7.1 probably also uses a 2.2 kernel (or even 2.4) I would say yes,
SUSE 7.1 supports this drive.
The trouble is setting it up to use SCSI emulation instead of direct
IDE control. CD burning software for linux is scsi based as far as I
know. The SCSI emulation is a kernel problem (which is also the reason
for me to say that SUSE wont have a problem with this drive).

Bernhard
