Yes. BUT...

XL-486 or 560?


I had to get:

  Title:   PCI driver problems with Novell Server & other software 
           that manages extended memory directly                                      

And install that into a CONFIG.SYS to boot via LOADLIN.EXE.

I have been told that this is not anymore neccessary since some
Kernel-Version, but didn't try, because:


>This PC has a QVision graphic card, and it is officially not supported.

It is; but ONLY in the commercial X-Server variants. 

For me, it was cheaper to get a new (and more powerful) PC with XFree
than to buy Accellerated-X :-)

I can buy the new AAR-2400 IDE RAID controller from my distributor but neither
they OR Adaptec have ANY information about available drivers (not even about w2k
drivers).

Any info?

Subject: 386 weirdness :(
Date: Thu, 26 Apr 2001 20:56:25 +0100

I'm trying to set up a D-Link DE-220 ISA network card in my old 386, but
am failing miserably...

The card is configured using a DOS based program which can disable PnP,
and manually set interrupts, I/O values, etc.

I set about trying to find a I/O rang IRQ which was free under Linux. I
tried several values in the 220-240 range, and when in Linux, I found
that these all seemed to be in use.

So I went back to the DOS utility, changed it to I/O 200 (I think), and
seem to have totally messed up the system. I now can't get back into the
setup.exe utility -- it complains that the card isn't found, or the base
I/O is in use.

It also seems to have messed up my hard disks -- rather than booting
properly now, the machine simply goes past the POST, and sits beeping
(at a rate of about 1Hz). If I disable the first HD in the BIOS (and
only leave the second one enabled), then it no longer beeps. Is it
possible that I could have somehow managed to mess up that hard disk
(and 80MB Western Digital)? It seems highly unlikely...

While trying to fix the problems with the HD, I have created another
problem -- if the IDE CD-ROM cable is connected to the sound card (as it
usually is), the screen doesn't turn on (it's an on board WD90c1 chip
IIRC).

Needless to say, I'm sure all power cables/IDE connectors are properly
secured.

All of this sounds totally unfeasible to me. Any ideas at all?

Cheers,

The motherboard is an ASUS CUV4X-D Dual Pentiums III ATX.   I've check out 
the ASUS homepage and this is what they have to say about this chipset:

>FC-PGA Dual Slot Series (5 PCI, 4GB DIMM)
>ASUS CUV4X-DLS is based on VIAŽ 694XDP AGPset that supports dual FC-PGA,

In otherwords the CUV4X-D used the VIA 694XDP chipset.

I've installed the failsafe image ie:

[gardiner@shalom /gardiner]# uname -a
Linux shalom.irus.2.4.2-2 #1 Sun Apr 8 20:41:30 EDT 2001 i686 unknown

And the SMP image is the 2.4.2-2smp image, and that is the one I can't get 
working.  Yes I've tried it to no avail which is why I'm writing here as 
per the last segment I belive it has something to do with VIA chipset 
giving problems.

Well, good question.  I don't think this is a memory problem.  I think its 
an IRQ assignment problem.  Apparently, or according to 
/usr/src/linux-2.4.2/Documentation/i386/IO-APIC.txt the IOO-APIC is an 
enhanced interrupt controller and if you read the crash sequence I provided 
in the original post 

[my post]

This is where its crashing.  But I will confirm High Memory support is not 
an issue before exploring further.

I found your sequence useful - it provides much more context.

No - see above where I posted the details.

Yes, but that doesn't mean my hardware likes RH's default SMP image which 
is the problem I'm having.

Also if you check out 
http://www.linuxhq.com/kernel/v2.4/changes/2.4.html#2_4_3

They basically note:
-undo some VIA PCI fuxups - conflicting behavior

which seems related to the problems I'm having above.

Tomorrow I'm going to further search the web for light were there is now 
none.

Ah, ha.  Excellent.  I knew that some would, but I didn't know that it
(probably) was part of the 64-bit spec.  Thanks!

Try booting:

 linux noapic

Who knows...maybe it works. This puts all IRQs back on one CPU. I do
this anyway, since early SMP kernels were more stable on my board (BP6)
with this option, and there is no detectable downside. At least for me.

Subject: Ultra160
Reply-To: [EMAIL PROTECTED]
Date: Thu, 26 Apr 2001 20:23:58 GMT

Hi

I keep hearing that hard disks are the slowest components of a computer.
About two years back, I read a very small article in a magazine about 
Ultra160.  I believe they called it SCSI2 or something like that, it was 
supposed to double as fast as a SCSI interface.
The article also claimed Ultra160 was compatible with Linux.
I'm wanting to hook myself up with a new desktop.  Considering I have an 
IDE interface now, if I can believe this article Ultra160 would be a major 
performance boost.
Can anyone confirm this?  Is there anyone here who has Ultra160 running 
under Linux, and wouldn't mind sharing his experiences with me?

Thanks in advance for any feedback

  Yes, you can find U160 SCSI controllers that work under Linux.  However,
it only provides a theoretical bus throughput of 160 megabytes/second.
Realisitcally, you'll still be limitted to the speed of the drive in a
single-drive situation, or the speed of the drives in a RAID array.  Even
using ultra-wide SCSI 2, offering 80 MB/second, you've still got more than
enough bandwidth for a single drive.

  Adaptec is iffy on drivers.  Some products have drivers written by third
parties, some parts they won't disclose the information.  I've used Mylex
cards with success, although installing to their newest models can be
interesting - RedHat 6.2 and 7.0 both have older drivers which won't
recognize newer Mylex cards.  I imagine that RH 7.1, with a 2.4 kernel,
should be able to handle them.

I've had two Yamaha burners die on me in the last 6 months,

The Plextors are burning both audio and data perfectly.

  Interesting.  I just built a few machines with those boards, and I know
that they work with 2.4 kernels.  They do mention something about an "unkown
apic" or the like, but they do work, and I haven't had to use the "noapic"
option on them.

   You do have two processors in it, correct?  (I'm assuming that you do.)
One other "gotcha" that I ran into was that I disabled the LPT port in the
BIOS, so one of the ethernet cards that I use (Intel 100's) was being
assigned that IRQ - but the LPT port was still responding to it, keeping
that particular card (of the three in the machine) from working.  I enabled
the LPT port in the BIOS again, the card got a different IRQ, and everything
worked.   That was verified on two seperate machines.

   If you have the LPT port disabled, enable it.  If it still doesn't work,
let me know, and I'll provide you with a copy of the .config that has worked
on my machines with those motherboards.

I believe that until 15,000rpm drives become cheap, you're not going
to get much performance gain from anything above ATA-66. Under SCSI2
with a Buslogic BT-958 and a Seagate Barracuda (7200 rpm) I was getting
around 10MB/s (measured with hdparm). With an HPT-366 (ATA-66) and an
IBM Deskstar, I get close to 30MB/s (again measured with hdparm).

Of course, I could be completely out to lunch.   :-(

x-no-archive: yes

I'm using an ATA100 drive under similar circumstances.  Most vendors,
IBM and WD to name a couple, have a utility which you should use to set
the DMA mode of the drive if necessary.  Some folks have reported
running into problems when using an ATA66 drive on an ATA33 port for
example.  Check the specs on the drive.  It may autosense the max speed
of the motherboard's port and adjust the burst rate accordingly or it
may not.  My IBM drive required me to use their utility.
