Hi,

I think '0xc0' is the code for the S3 Vision864 chipset on

your card. This chip is not supported under Xfree2.1.1. Get

Xfree3.1. It should work then.

Sounds like a problem I just had. I also added a Sound Blaster and
|
|
CD to my system (Sony CD in my case). When I added in Sound and CD
|
|
support, the system would hang when probing the NIC (old Tiara 1000,
|
|
ne1000 clone).
|
|
|
|
Bottom line was, both the Soundblaster and the NIC were set up for
|
|
DMA 1. I reset the NIC to DMA 3 and everything plays fine.
|
|
|
|
Good Luck!

The patch sets a times just before close(0) and if the system does not return
|
|
from close(0) the timer will execute an exit(1). It works well, and happens
|
|
about 25% of the time.

Right now I've installed Slakware 2.01 on my PC (486DX2-66,ASUS SP3G,

I am running 1.1.52.
|

I found it necessary to run:
|
|
|
|
# /usr/sbin/setfdprm -p /dev/fd0h1200 1200/1200
|
|
# /usr/sbin/setfdprm -p /dev/fd1H1440 1440/1440
|
|
|
|
so I could fdformat floppies.
|
|
|
|
Look in /etc/fdprm.
|
|
|
|
Mounting is done:
|
|
|
|
# mount -t minix /dev/fd1H1440 /mnt

|

Seems to work for me.

I ran into that bug myself. A look through the patch reveals the

problem: Just delete fs/binfmt_elf.c before applying patch54, and

Hi,
|
|
I have also been trying to use the Linux NFSD for real work. The
|
|
biggest problem I find is the lack of a lockd/statd. I have done some
|
|
elementary profiling work on the nfsd, and find a 5:1 ratio of time
|
|
spent in system vs user mode. (linux 1.1.52 -> Linux 1.1.18 and
|
|
Linux 1.1.52 -> DEC OSF/1 vn 2.1). Profiling of the nfsd (using
|
|
bprof) shows no obvious black spots in the existing code. I just get
|
|
the feeling that the design is deficient, when compared to the source
|
|
of the *BSD setup.
|
|
In terms of throughput, on a quiet LAN using Linux as client + server I
|
|
get the following results. (client = Linux 1.1.52 + florians nfs patches
|
|
on a 486sx33 8mb ram)
|
|
(all drives mounted wsize=rsize=4096, + measured using iozone 64 4096)
|
|
Figures good to 10-30 k/s only. (this was not an exhaustive test)
|
|
server read write
|
|
486sx33 8mb ram IDE disk = 150k/s 154k/s (read+write ~ equal)
|
|
486dx66 8mb ram IDE disk = 210k/s 200k/s (read+write ~ equal)
|
|
486dx66 16mb ram IDE
|
|
+ promise cache (4MB) = 350k/s 350k/s (At ethercard bandwith)
|
|
|
|
However, using DEC OSF/1 as a client..
|
|
486sx33 8mb ram IDE disk = 353k/s 246k/s (almost ethercard b/w)
|
|
|
|
Using tcpdump, it is interesting to note that OSF/1 is issuing a short
|
|
read request after every write. Dunno why. Linux clients do not.
|
|
|
|
These figures should only be taken as a rough guide to performance,
|
|
but they reflect the subjective performance levels. The real winner
|
|
here is the promise hardware cache. (This machine flies...) I am
|
|
at a loss to explain the figures from OSF/1. It is repeatable.
|
|
It is also extremely easy to overwhelm a linux nfs server with traffic from
|
|
an alpha (3000/400 with 96mb ram) at a block size of 8192. Still looking
|
|
at the tcpdumps to see if I can sort the reason for this.
|
|

The single-threadedness of the linux nfsd gives an important
|
|
advantage in that that NFS locking is not so important. I have the
|
|
scenario of having multiple IBM PC's running PC/NFS using a Linux
|
|
1.1.52 box as a server. I am reasonably worried about locking, but,
|
|
as only one NFS request is active at any one moment and as the NFS
|
|
implementation is synchronous there should be no direct conflicts.
|
|
(Obviously this doesnt prevent each pc from overwriting a file that
|
|
the other is writing to with sequential requests, but it does avoid
|
|
the scenario of two nfsd's trying to write to the same byte-range at
|
|
the same time.)
|
|
|
|
If there were one nfsd (supervisory) and several block i/o d's
|
|
running, as is the case with OSF/1 and SunOS4 with requests from
|
|
different machines/processes executing concurrently, then I'd regard
|
|
the presence of a lock manager as being essential.
|
|
|
|
The question comes down also to O/S design and Colonel Bloat. If
|
|
the nfssvc() was a stub into (flavour of the month) a loadable module,
|
|
that contained all the nifty performance enhanced kernel based
|
|
asynchronous NFS with hooks into the buffer cache, then i'd happily
|
|
insmod this into my Linux NFS server, and leave it out + save memory
|
|
on the Linux NFS clients. Being an NFS server is less common than
|
|
being an NFS client. Personally I would rather have nasty but fast
|
|
monolithic kernel based NFS server, than settle for a slow user-space
|
|
server approach.
|
|
|
|
Having said that - please note that;
|
|
1) I really dont know what I'm talking about.
|
|
2) I still don't understand much of the code in the current nfsd
|
|
3) I am really grateful to Mark Shand, Rick Sladkey \etal for doing
|
|
what they have done so far. I wish I had the time/ability to help
|
|
out. (Being addressed.)

Yup.

Nope, blame MS, they won't release the layout of the filesystem.

In order to have four drives running off a single controller, you need to
|
|
define ALLOWED_DRIVE_MASK to be 0x0f. ALLOWED_DRIVE_MASK is a bitmask of the
|
|
allowed drives (by default drives 0 and 1 of both controllers).
|
|
ALLOWED_DRIVE_MASK was introduced because probing drives 2 and 3 resulted in
|
|
system hangs on some PCI boards.
|
|
Hope this helps.

In the wee early hours of this morning, I was Linuxing away and my entire
|
|
system froze up on me. Finally after a long time, I had to hit the RESET
|
|
button.
|
|
|
|
Now, when I boot up, it gives me a prompt with the none in it.
|
|
|
|
(none)~/ (now)
|
|
brutus/ (in the past)
|
|
|
|
It appears all my stuff is there but I cant do anything with it. I tried to
|
|
do a fsck but couldnt find it. I tried to mount, dismount, halt, shutdown.
|
|
Nothing seems to work. In fact, only mount and dismount are even found. This
|
|
may be a path issue but I am not sure.
|
|
|
|
The mount and dismount commands produce an error saying something about
|
|
/etc/mtab~ cannot be created because file system is read only. I then went to
|
|
my boot diskettes and brought the system up also with read only.
|
|
|
|
I really need to get this back up and running soon. Any help or suggestions
|
|
would be greatly appreciated.
