not -exactly- a telling test. do the same thing using a unix browser
against a remote filesystem. it still takes a while for it to display.

linux might be fine with a smallish filesystem, but if you take it too
large and ever have to fsck it... go get dinner and a movie. as to HP-UX,
dont even consider using it for NFS. relative to Sun and SGI (or even a
NetApp), it's a horrible performer.

problem really isnt the hardware but the software running on it. solaris
x86, linux and BSD boxes ive had the pleasure to work on have been pretty
reliable. throw a M$ OS on them, and that's when they got crashy.

as a fileserver, the 64 bitness isnt really going to help, except with
allowing for large filesystems (isnt the figure for XFS something like 9M
TB? at least according to the "SGI to Open Source XFS" article on ZDNET).
What really buys you something on a server is the number of network file
service requests/sec. it can service, how big the filesystem can grow, and
whether the filesystem has good failure recovery (underlying RAID and
journalled filesystems).

Hmm. Can't speak to that. The VFB thing worked for me.

Yea, it's because (if I am right) the console is connected to /dev/fb
instead of /dev/console. Since svgatextmode works on
/dev/console.........

XIG seems to return to /dev/console instead of /dev/fb. I had the
same problem with mine and reported it as a bug. I haven't heard back
from them other than 'it's off to engineering, thanks for the tip'.

I doubt this. to test that theroy play around with svgatextmode
without loading into VFB modes on bootup. If that exhibits the
behaviour, it's the card. If it doesn't, it's the VFB stuff.
But that's just my 0x02c.

I am highly surprised that the temp can be checked by the computer
itself. Can you elaborate where exactly I find this function in the
BIOS? Or maybe it only works for ATX motherboards?

Indeed. My Alpha/166 system is absolutely *not* the equal of a 400MHz
IA-32.
It is instead roughly the equal to a P75/P90, thus suggesting a rather
different ratio, such as that PC's with IA-32 architectures have
approximately twice the computing power of an Alpha-based system of the same
clock speed.
I would not, however, promote *that* position either, as it is not a
reasonable characterization of either Alpha or IA-32.
A fairer claim would be that for FP-intensive operations, Alpha systems are
comparatively a *lot* faster than IA-32 systems of similar price.
It is not clear which processor has advantage when working with highly I/O
intensive operations; that is liable to be dominated by:
a) The speed of the disk system, and
b) The rate at which DMA can move data back and forth between memory and the
devices.
In that circumstance, Alpha won't have a substantial advantage.
In applications involving hefty amounts of integer calculations that can fit
into 32 bits, IA-32 appears to be a more economical answer.
When 64 bit values start to represent important factors in applications,
Alpha will doubtless look better in that it can do things in one instruction
that likely take 4 or more on IA-32.
Those are the sorts of factors that *should* be used to assess which
architecture will be preferable; the blanket assessment that
"AXP = IA-32 * 3" just makes the proponent look ignorant.

The problem is that I ALREADY have the spare IDE disks and I would like to
be able to use them. If I go for SCSI it's buying the controller and the
disk, which is a LOT more expensive and would leave those IDE HD's in the
drawer of the desk. What I was looking for is a way of using what I have, as
cheap as possible. A PCI controller should be cheap, don't you think?

Reply-To: [EMAIL PROTECTED]
I've read a few messages about other people having problems with
installing 6.1. I have the Adaptec 2940 UW, and during boot it
ends in an infinite loop with something along the lines of
"SCSI host 0 aborted (pid 10)
timed out -- resetting
SCSI bus being reset for ...
SCSI host 0 channel 0 reset timed out -- trying harder"
Several other people have written about having had this problem,
and some other people have been successful in booting and
installing. My question is whether anyone who previously
had the problem above was able to remedy it.
I have tried creating boot disks with the scsi01 kernel image,
but that didn't help at all. I've all but given up on SuSE 6.1
and am currently using 5.3 again.

You need to make sure you have the latest XFree86. v3.3.3.1 added
support for the original riva TNT. Then you need to configure X to use
the SVGA server. Lastly, manually add the following line to your device
section:

This worked for me. I've posted my XF86Config if you want to use it as

Actually your root partition can span the 1024 cylinder border so long
as your kernel image is below. This is splitting hairs I know but just
as some FYI so long as the kernel image is below the limit then the
kernel can be loaded.
I ran into this on my machine. I had put a new 4GB drive into it and out
of laziness just put everything on one partition. It booted fine
because the installation process dumps the kernel under the cylinder
limit.
But one time I rebuilt my kernel and did a make zlilo to install it and
then rebooted ... BOOM! Didn't work and I could not figure out why. So I
booted off diskette and mv'd the old kernel back, IOW just renamed it
and rebooted. Everything worked fine.
Turns out that when the new kernel was moved into / some of it's disk
blocks were past the cylinder boundary and so it crapped out, but the
old kernel was still within the boundary since it had simply been
renamed.

It depends on the individual motherboard. Some have on-board sensors to monitor either
ambient case temperature, CPU temperature, or both. My Abit BH-6 monitors ambient temp
only. I can access the readings from in the bios setup, or with 3rd party software in
windows, which monitors the temperature sensing chip. (Winbond LM-79). Intel does
supply
recommendations for target ambient case temperatures for it's processors to maintain
adequate heat dissipation with either active or passive cooling solutions. The
recommended
ambient case temp for my Celeron 300a is 45 degrees Celcius. Whereas, the maximum
thermal
temperature rating for the CPU itself is 85 degrees Celcius. This is not the normal
operating temperature, but the maximum rating for the chip. It might work at that
temperature, but probably not for very long. :-) There's no reason that temperature
monitoring cannot be used in AT motherboards (I'm sure many offer it). It is not an
exclusive feature of ATX boards.
