It is entirely possible that the questions that you asked have well
documented answers in all the usual spots, and that the same questions
appear week after week on the newsgroups and everyone is tired of seeing
and replying to them. On the other hand, I have absolutely no idea what
you asked, and so I have no idea whether this is actually the case or
not.
As you are using dejanews, you likely have looked thru the previous
postings for the last couple of years, and you perhaps can find your
answers there. Or, try the LDP at http://www.kernelnotes.org/LDP .
Good luck.

I get segmentation fault when i'm trying to install slackware 4. When
i'm going to select TARGET (root partition) the system segfaults and
then it's very unstable. I think this has something to do with my
hardware which is an AMD K6-2, motherboard with the VIA MVP3 chipset
(100 mhz bus), PC 100 SDRAM, an IBM Deskstar 16GP harddisk(UDMA) and two
NICs (NE2000-PCI and one 3COM 905B). What could cause my problem and is
there a fix for it? I mean can i do something in bios or anything like
that?
Thanks in advance.

go to a computer show and look for a dual ppro-200. these things are
still pretty fast and are now going at firesale prices. last year, i
saw whole systems (2 ppro-200s, mobo, case, keyboard and mouse, not
sure about harddrive but i think so) going for $400. that may a bit
high now.

You don't say which kind it is, but, with a 1 gig drive, it is probably
a Sparc of some kind. OpenBSD is what I run on my sparcs (wish there were
a FBSD suite.....(:+{{.....). It loads fine, and runs out of the box.
The all in the monitor thing I am thinking is an X terminal, although
you can reset the prom contents at one location and it becomes a regular
Sun box.

: Students can also get cheap (or free?) Solaris, AFAIK...
I have tried Limux on my IPX Sparcs, and it does fine, but, it loads
everything but the kitchen sink from RedHat6. I prefer the leaner
OpenBSD load, usually. I can't comment on Solaris, other than it is
SLOOOOOOW, compared to OpenBSD, or even Linux.

OpenBSD 2.5 is stable. Linux RH6 is stable.
I load mine with either from a FBSD box with a CD, via ftp. Works fine.
Mount the CD on the FBSD box, and then ftp when it calls for the files.
If the scsi drive is generally OK, the OpenBSD will load fine. IFF there
are formatting errors on the scsi drive, you may need to format it on
something else, low-level (the Sun will do that from Sunos, or do it on
any old PC with a scsi controller and the manufacturer's low-level util.
Get the Solaris Netscape, and load up three libs from Solaris (ld.so,
libc.so.somethingorother [it will tell you which it is], and one other).
Also, move the Netscape nls and its sun libs into the lib tree,
appropriately.
Good luck.
Now back to FBSD.....

Our internet-gateway:
486DX2 66MHz, 16Mb RAM, 340Mb HDD, 1980s VGA-card. Runs Linux 2.0.35
from SuSE 5.3 - acts as YP-server, DNS, DHCP, Internet-gateway.
Installation includes full source-tree.
If you want to run DOS and Linux using just your 350Mb drive, I suspect
you'll be
little short of diskspace. But it depends very much on what you want to do.
I have an old 385SX25 somewhere, that I once did attempt to get running with
Linux - but the 2Mb of RAM just wasn't enough. Though there is a parameter
that might fix even that!

I recently purchased another parallel port Zip drive and discovered that it
will not work under Linux but works fine in Windows and DOS.
My older (about 1 1/2 years old) Zip drive works fine under Linux or Windows
on the same computer.
I've tried the 2.0.36 and 2.2.5 kernal with the same results.
Any ideas?

Ummm, the point of the original posting was that Linux kernel will not support
more than 16 separate scsi devices. If the kernel doesn't support a higher
number, creating the extra device entries with mknow just won't work. The
original poster might want to look into the devfs patch, which might provide
relief.

Subject: changing irq with setpci and kernel 2.2.*
Date: Fri, 28 May 1999 18:05:42 +0100
Hi all,
I'm trying to change the irq of the following device:
00:10.0 Ethernet controller: 3Com Corporation 3c900 Combo [Boomerang]
Because it uses IRQ5 by default and I want it to use another one (eg: 7)
IRQ5 will be used by an ISA Plug and Pray sound card (Oh my God)
Trying the following command line:
setpci -s 00:10.0 INTERRUPT_LINE=7
(Tried while driver unloaded and loaded)
I cannot change ethernet's IRQ... what I'm missing?
I have checked around the net and docs without no luck at all...
Any comment/suggestion will be greatly appreciated
Thanks in advance,
Ulisses

This is kind of basic, sorry.
If you are just going to reinstall, just let RedHat detect the card and you'll be good
to go. If
you are recompiling the kernel, make sure you choose to install the kernel sources
during the
package installation.
Change directories to /usr/src/linux
Do a 'make menuconfig' or 'make xconfig' if you are running in x
Go to the scsi section and choose Adaptec 78XXX series
Make sure this is not a module
If you have a scsi cd-rom, tape, or misc device check those appropriate boxes.
If you want the scsi verbose error reporting choose that
Uncheck any other scsi control (my kernel sources came default with all the adapters
enabled)
Save configuration and exit
Do a 'make dep'
Do a 'make clean'
Do a 'make zLilo' - I believe this is correct, but check the kernel compiling section
of your Red
Hat book.
That should take care of it. Sorry, but I don't have my linux machine in front of me
other wise
I'd give you the exact options. Hope this helps, if not let me know and I'll check my
system.
(I have a 2940 too).

Ok Before you asserted $150 difference, now you've raised that to to
$550 ... The 30% difference in your vs my CPU costs at $150 wasn't
worth the diversion, but the reality is that for someone building
a system the difference is about $100 on a dual system:
http://www.shopper.com/pfind/cpu.pentii.333mmx.html $125.50
http://www.shopper.com/pfind/cpu.cel.333mmx.128k.html $ 72.95
CPU Price difference: Uni $52.55, Dual $105.10
So, a 9% increase in cost for a Dual PII, delivers a 20% speed up
by your benchmarks. The same 9% also makes the system stable for
working sets that are 5-8 times larger. Stated in reverse, saving
the 9% in system cost, reduced the performance by 20% for your
benchmarks ... that is NOT a good value from a price/performance
perspective ... expecially when the price/performance tradeoff gets much
much worse for applications with larger working sets with Celerons.
How is it that Dual Celerons are better? Simply that they may be
overclocked higher, which for small working set computational
applications makes them a bit faster. However, if the working set
includes the normal X11, filesystem and/or networking OS features, the
working set is then expected to be significantly larger than 128K,
and there is a significant risk the dual Celeron system will run MUCH
slower under load, with the posibility of being slower than a
uniprocessor PII due to L2 cache thrashing and extensive memory
contention.
How this maps to a particular users application requires some study,
but I expect that the core OS services that boost the foot print are
used in more applications that the relatively tight inner loops that
dominate gcc's execution profile. Hence my concern that saving $100
for a Dual Celeron, is a very poor tradeoff for most people. And
almost certainly for database, Web and file servers.

Support for the SCSI needs to be build into the kernal if you want to boot
to a SCSI disk. You will need to rebuild the kernel and add support for your
NCR53c810 into the kernel. You cannot boot if the scsi support is in the
form of a module.
Hope this is helpfull
