Hello.
I have an ide Colorado TR5 tape that I can happily back up one partition
and restore it using:
/sbin/dump 0af /dev/ht0 /dev/hda1
On sun boxes I use a dump script to dump multiple partitions to 4mm tape
using a shell script. I have to define block size density and length for
the dump to be restorable.
I wrote the following (commented lines) and cannot restore a specific
partition using:
/sbin/restore -s 2 -if /dev/ht0
#!/bin/bash
#
mt -f /dev/ht0 rewind
#/sbin/dump 0af /dev/nht0 /dev/hda1
#/sbin/dump 0af /dev/nht0 /dev/hda2
#/sbin/dump 0af /dev/nht0 /dev/hda3
/sbin/dump 0absf 64 2300 /dev/nht0 /dev/hda1
/sbin/dump 0absf 64 2300 /dev/nht0 /dev/hda2
/sbin/dump 0absf 64 2300 /dev/nht0 /dev/hda3
mt -f /dev/ht0 rewind
mt -f /dev/ht0 offline
I thought maybe I'd need to provide (like the 4mm tape on sun boxes here)
block size (64) but I cannot figure out the density and length of TR5
Travan tape. Does anyone know what they are, and if provided as arguments
to the above /sbin/dump in the above script, will they allow multiple dumps
per tape and then restore specific partitions using the -s argument in
restore.
Thanks in advance, and upcoming too.

I haven't studied your specific question, but let me raise
another point. I have the same drive, but I use tar to backup.
I've found the mt command cannot place me at the appropriate
tape archive for recovering something if I put multiple archives
on the same tape. (The same thing happens on a Travan SCSI
tape drive we had.) But if I do an
mt -f /dev/nht0 weof
between the archives, then I can position the tape using twice
the requisite number of skips.
Have you checked if the same thing happens for you?

According to Martin Høyer Kristiansen [EMAIL PROTECTED]:
The benefit of UDMA 66 in current systems is very modest, because
current controllers are limitid to one UDMA 66 device per controller.
Does this mean one *active* UDMA-66 device or one UDMA-66 device
period? Are you allowed one UDMA-66 and one UDMA-33 device?
I haven't bothered to take the plunge to UDMA-66 quite yet...
Regardless of these restrictions, I would *never* put more than one
device on an IDE controller if speed were an issue, especially since
IDE controllers are so cheap (even the UDMA-66s nowdays)
The point of higher bandwidth is that the controller would be able to
saturate more devices, but because of the one device restriction on UDMA
66, performance are dominated by the slower device-interfaces.
Not entirely true. 7200 and 10K RPM drives will show better
throughput on UDMA-66 vs. UDMA-33 controllers in a single drive per
controller situation. (or so I have read in several places.)

work
It's not a winmodem , it's a sporster voice 33,6 internal
HELP PLEASE

CPUs are synchronous,
Maybe we're running off a different definition of "synchronous". From your
description, the bus speeds are synchronous not the CPU speeds (since the
multipliers are different).
For each 11 CPU clock periods of Celeron550, Celeron450 has 9 periods.
Different speed but synchronius operation :-)
In any case, I'm quite impressed (and surprised) that these combinations work.
I'd be interested to see how your benchmarks results differ when reversing the
order of the CPUs. (ie, with your Celeron 550 + PII 350, switch the CPU
sockets to see if the threads are still allocated the same).
I didn't think about this. I will try when I have some free time.
Onother interesting thing is which CPU will boot as primary. I thing
it will be the faster one.
Pozdrowienia,

It's interesting to note that the dual PII 350MHz chips were
faster then the Celeron 450+PII 350. I wonder if this is caused by
the simple fact that PIIs work better in multiprocessing systems, or
because the running SMP systems with asynchronous processors causes
other problems. My guess would be the latter.
I think that Linux scheduler is not optimal at dividing tasks between
different CPUs. I made also some estimation of one CPU "power" in
single and dual setup:
P2 350 1.0 reference
Cel. 4501.2
Cel. 5501.3
P2 350 dual 0.8
Cel. 450 dual 0.7
Cel. 550 dual 1.0
You can see, that Celeron 450 is rather weak at dual setup, but
Celeron 550 works well in both setups.

Hi,
Try this: http://www.dyer.vanderbilt.edu/server/udma
The patches are beta and not always work: good luck.

Hi,
are there any kernel patches which enable busmaster DMA with the ALI
(Aladdin) M5229 chipset? On my system (K6-2/400, 128 MB RAM, Asus P5A,
IBM DTTA 10GB), disk access from Linux is terribly slow, which causes
very long startup times for e.g. KDE or Netscape.
On startup, the kernel reports something like the following, though DMA
is definitely enabled in the BIOS setup:
PCI-IDE: simplex device: DMA disabled
PCI-IDE: ide0: Bus-Master DMA disabled (BIOS)
PCI-IDE: simplex device: DMA disabled
PCI-IDE: ide1: Bus-Master DMA disabled (BIOS)
Any pointers to source code or any workarounds are welcome
Bye,
Frank

Well, I just heard of this thing called X, supposedly it's
this graphical thing for Unix, rumour has it there's even some
applications for it. Stuck in the 70's as I am, I don't think
it will ever be of much use to me, but you might want to check it out.

If you are looking for RAW FP power look at an ALPHA processor. Load it up
with memory and fast disks.
How does memory and disk speed relate to FloatingPoint
performance? This thread has my attention because a friend
at Qualcomm said he got better performance out of a PPro
then a Sparc 10 when doing simulations on voice codecs.
That surprised me and I'd like to know how the Alpha does FP.
Something more logical of a response is needed to be CONSIDERED

This sounds like the problem I had in RH5.2. The MS Intellimouse PS/2 would
work at the console screen and then at the X window screen. But if I exited
X
back to the console the mouse would barf. This mouse has a wheel button
so I downloaded the 'imwheel' program from freshmeat. This program
includes a patched gpm which solved the mouse barf problem. (Note: the
original gpm did not show 'imps2' as a valid mouse type if you run 'gpm -i';
the patched one does.)
Here's the file /etc/sysconfig/mouse file I'm now using:
MOUSETYPE="imps2"
XMOUSETYPE="IMPS/2"
FULLNAME="Microsoft IntelliMouse (PS/2)"
XEMU3=no
