That's impossible, because the kernel does what you tell it to.
If you tell it you have 1GB of ram, it will believe you, and then crash
trying to access it.

That you either start realizing that you are not doing what you think you
are doing, or start telling us what you are doing, instead of telling
us what you think you are doing.
The procedure in reporting an experiment and your observations of it
is taught in most secondary schools ... and you clearly know how to!
So, come on, make an effort ...

I would check the specification of the Seagate WC drive. I believe that
model numbers ending WC are Differential SCSI rather than Single Ended
SCSI. I believe that the Adaptec 2940UW is a Single Ended SCSI. I
suspect a fundamental incompatibility in the SCSI Bus specification and
you may have to buy/obtain a different SCSI Controller card. It also
affects the SCSI Terminators.
Differential SCSI uses Balanced pairs of wires for signalling (i.e. one
wire goes +Ve while the other wire goes -Ve. They (the wires) then
revers polarity between 1 and 0). Single Ended SCSI uses one wire as a
Signalling Earth while the other wire swings between +Ve to represent
one state and -Ve to represent the other state. This allows number of
Signaling Earth Wires to be reduced by making a number of signalling
paths (Data/Control bit) to share Signalling Earths.

Hi Sinner!
When I bought my WaveLAN card, they came only as PCMCIA, and I put mine
in an ISA bridge. There's also a PCI bridge, but iirc there may be
problems with it. Check out
http://www.fasta.fh-dortmund.de/users/andy/wvlan/ and the links off that
page. As to buying them, I couldn't find any bargains, though I didn't
look much further than the links off Orinoco's page. Mine was maybe
$170 + another $70 for the bridge(?) At the time it wasn't clear that
there was any alternative to WaveLAN if you want to talk to AirPort
cards, as I did.

In my experience, XConfigurator is subpar compared with SaX,
XF86Setup, and xf86config. SaX is SuSE-specific, but the other 2 are
part of X11R6 and should work at any time with anything that Xfree86
supports.

"rm -f /etc/X11/XF86Config " and see if XConfigurator will let you write
a new file *then*.

Subject: Hardware RAID Options?
Date: 5 Dec 2000 01:10:34 GMT
Reply-To: [EMAIL PROTECTED]
The folks at my place of employment are looking to build a Linux box
with a reasonably large (~290G) SCSI RAID-5, and would like to have a
hardware RAID controller. I did some grubbing around on Deja, but
didn't find as much as I'd thought.
The box we're looking at is a Dell PowerEdge, where one of the options
is a PERC2-Si controller (aka "AMI MegaRAID") that I'm sure is
supported. One Deja post from about 10 months ago said the performance
on that particular card wasn't so hot--still true? And does anyone have
any information on the PERC2-DC or PERC2-QC controllers that are also
available? Those came up empty on Deja. I should know more about this
stuff, but due to financial constraints, most of my Linux experience has
been on lower-end hardware.
FWIW, this machine's main purpose in life will be as an FTP server, and
it'll eventually handle 12G or so of data per day. It will also handle
a bit of Apache stuff, some automatic processing of uploaded text files
via Perl, and Quake3^H^H^H^H^H^Hpossibly other mission-critical
applications as needed. Spec follows:
Dual PIII 866MHz
Dual 330W powersupply
512M ECC SDRAM
5 73G SCSI drives for 292G in RAID-5
Intel EEPro 10/100 Ethernet
DLT1 (40G uncompressed) Tape drive
Vanilla keyboard, mouse, SCSI CD-ROM, monitor, floppy
Any comments/criticisms/suggestions appreciated; please post to the NG
as I spend a great deal of time here anyway....

Hope it isn't i840 chipset. You'll need to run kernel option noapic if
it is, or suffer crashes. Running it with the IO-APIC disabled means
hardware interrupts are handled by only one cpu, and responsiveness
under load will degrade. I've recently seen reports that the ServerWorks
chipsets are reliable; BX is also reliable. Avoid i840 like a disease.

If you haven't purchased the drives already, consider Ultra 160. Even a
single high-performance drive will do things most regular drives can't
do on software RAID. I can't guarantee it, but I believe several of the
Ultra 160 RAID cards now run on linux. The drives themselves are not
particularly expensive relative to older scsi products; you can look for
some approximations on prices for drives and controllers at
http://www.necxdirect.com/hai/serve_page.html?file=docroot/drives.html&nonce=guest
(this isn't a plug for necx, but I find the prices representative of
other "reasonable" resellers).

I used to recommend NE2000 cards as you can get them for $5 at pretty
much any computer swap meet / junk store etc. However I've had a few too
many problems with them losing their settings and doing other flakey stuff
lately, so my current favourite old ISA network card is the 3COM Etherlink III
aka 3C509. When you can find it it is generally just as cheap and like the
NE2000, you can configure its EEPROM settings (IRQ, I/O address) with a
Linux utility, available here:
http://www.scyld.com/diag
In addition, you can download support software from 3COM's site so if you
have DOS handy, you can make a bootable floppy and use their nice GUI setup
utility. Best of both worlds.
The only catch, compared to PCI network cards, is you have to manually
assign I/O addresses and IRQ numbers. My biggest problem is that I always
forget to
cat /proc/interrupts
cat /proc/ioports
while teh machine is still up, then I'm staring at the disassembled parts
and thing, dang, I can't remember what interrupts are free!
Enjoy.

I've got a old SMC Ultra ISA card. I like it because it has jumpers
for IRQ and such.
I think it's that way, the machine has been up for 2 years and
my brain needs to be booted more than it does.
