Linux On Dell Dimension XPS R450

Post by Ralph Albert » Tue, 15 Sep 1998 04:00:00



I am in need of purchasing a new computer and it must run Linux as well as
Windows 95/98/NT. I would like to purchase the latest greatest speed demon
from Dell but am concerned that it will be incompatible with linux. Has
anybody had success run RedHat 5.0 on the newer Dell machines?

Dell hardware specs that I am concerned about:

1)   4.8X DVD-ROM Drive - The literature states that it is backward
compatible with standard CD-ROM drives but I have read that Linux is not
compatible with DVD drives.

2)   14.4 GB 7200rpm Ultra ATA Hard Drive - I thought I read that Linux has
a problem with Ultra ATA and Ultra DMA hard drives.

3)   STB nVidia ZX 8MB 3D 2X AGP Graphics Card or an ATI Expert 98D 3D 2x
AGP Graphics Card

4)   Turtle Beach Montego A3D 64-Voice PCI Sound Card

5)   10/20GB EIDE TR5 Tape Backup

6)   56K Capable U.S. Robotics V.90 x2 Modem - Can the modem be an internal
modem or am I better off not buying an internal modem from Dell and getting
an external modem?

Thanks for your help.

I'm considering one of these myself. I'm pretty sure the USR modem
is one of those WinModems and is about worthless. I'd get them to
delete that and buy a good external non-WinModem.

Anybody else have RH running on one of these?

There is an option for configuring the Dell System with a modem for sound
but I am not sure if it is a winmodem. Good point.

One way of making sure a modem is not a win-modem is as follows. It is
'normal' for Dell (certainly in UK) to insist that they only ship
WORKING systems. (I have previously asked for a machine without a hard
drive - I did not want to buy windows 95, and on another occasion I
didn't want *another* monitor ...) So, dell insists on shipping a FULLY
functional system.

The trick is this. Ask them to pre-install Win NT, not Win 98. This
costs (in the UK +/- 30 or so more), but then you are guaranteed that
the hardware is not a Winmodem, or anything is windows specific only. As
a broad rule, if it is NT compatible, it is Linux compatible.

This might be an attractive alternative. Anyway, it is woth a shot.

Don't know about this Dell but I would do two things. 1)Ask them if they
can config the machine with Linux so they will know the public wants it,
2)check www.varesearch.com

Wrong.  Linux works just fine with DVD drives.  There is no software yet to
view DVD movies or read DVD filesystems, but the drives work fine as CD-ROM
drives.

Wrong again.  The latest versions of the linux kernel even support UDMA
transfers using Intel and VIA chipsets.  Older kernels will work with UDMA
drives, but won't be able to attain the higher speeds possible with UDMA.

Quote:

Not completely sure about this one.  I have a nVidia Riva 128 4MB card
(Diamond Viper v330 AGP) that works very well; I'm not sure if the nVidia ZX
is compatible with this driver.

Quote:

> 4)   Turtle Beach Montego A3D 64-Voice PCI Sound Card

Dunno.  I'd stick with an AWE64 or a Crystal CS423X chipset.

Quote:

Should work fine.  IDE tape drives are supported.

Internal modems are fine; however, be sure this is NOT the WinModem.  I have a
3Com USR 56k PnP modem that works great.

Here's my system just for reference:

Micron Millennia PII/400
Intel SE440BX motherboard
128MB RAM
Diamond Viper v330 4MB AGP video card
Diamond Monster 3D II 12MB PCI 3-D accelerator
Diamond  PCI DVD MPEG decoder card
On-board Crystal Soundfusion (CS4232) sound
Maxtor 10.1GB UDMA EIDE HD w/Win98
Western Digital Caviar 5.1GB UDMA EIDE HD w/Linux
Hitachi GD-2000 DVD drive
IOmega internal EIDE Zip Drive
1.44" floppy
3Com/USR 56k PnP Non-WIN modem
3Com 3c590b PCI 10/100 ethernet

All of the above hardware works in Linux (Red Hat 5.1 with 2.0.35 or 2.1.121
kernels) except for the Diamond DVD board which is recognized by the kernel
but which I have no Linux software for.  I've even installed Glide 2.53 to
allow me to play GLQuake and Quake II on the Voodoo2.

Slight workarounds: the Viper video card required that I upgrade to the
XFree86-3.3.2.3 release since the 3.3.2 release doesn't support IRQ sharing.
The Crystal Soundfusion and the modem required that I manually configure ISA
PnP.  The MS Intellimouse-with-wheel worked fine, but I ditched it for a
proper 3-button Logitech MouseMan.  Finally, due to MS' ill-behaved PCI PnP, I
have to power down the machine after running Windows 98 in order to reboot to
Linux, or the Ethernet card gets hosed up.  Soft reboots between Linux
sessions work fine.

Hope this helps somewhat.

Phil

I'm looking at the same system.  I'm pretty sure the upgraded
modem is not a winmodem.

Dell has been installing Linux on their systems for almost 2 years, but
just now making it "public".  You have to be a large customer to get this
done (or pay $250 extra), but you can specify that you wish to install
Linux and want to get the appropriate hardware.

What ? install NT so you can run linux ? this is starting to blow my

I know it sounds strange to ask for NT when getting a computer for
Linux, but I have dealt with Dell a couple of times (Dell UK that is),
and this was the easiest and most cost-effective way of doing it to a
guaranteed level of hardware support.

I like Dell as a company because I have had good experiences with them,
and I am open-minded / naieve enough to believe that they have "core
competencies" which do not include Linux. Thus, they do not openly (or
any other way, except if you are a corporate customer I believe ...)
support it. Although it would be nice if they did support Linux, I don't
hold it against them that they don't. I like their hardware / support /
service / pricing, not necessarily their "software" policies.

The subject line is "Linux On Dell Dimension XPS R450" which indicates
that the original poster (I forget who now), was specifically wanting
Dell.

I found that, with Dell at least and probably other companies, that they
will generally only sell pre-spec'ed systems. If you want to build a
custom system, it comes at a (significant) premium. On the other hand,
if you look at their advertising, they offer standard OS's for only a
marginal extra cost which in the case of choosing NT over Win98 gives
you the same basic spec as the advertised machine, but also ensures that
everything is NT compatible (and thus, as a generalisation, Linux
compatible).

I found that the premium of asking for an NT OS was less than the
premium of upgrading the modem (the computer was specced with an
"internal modem", and arrived with a USR Sporster flash external ...!).
Even paying this premium, the result was a hardware platform I am more
than happy with, and service I am happy with, and an operating system I
am happy with (Linux), and a copy of NT (workstation) which is now on
another machine. I felt a "winner" in the whole deal.

Why don't I buy pre-configure Linux machine?

Firstly, I considder the hardware and OS to be independant to a large
degree, so the question should be stated "Why can't I buy a computer
*without* an operating system?" You have to buy the OS even if you have
an OS already, like Linux / windows / OS/2 whatever.

Second, pre-loaded Linux (at least in the UK) is a "specialist" and not
a "consumer" product. This attracts a "specialist" premium on the
system.

Third, Why pay someone to install a free operating system when it is
beneficial / easy / educational / free to install it yourself?

Fourth, I am a brand name buyer. I buy Sony electrical / audio-visual
products where there is a choice, I buy IBM HDD's, I buy Colgate
toothpaste and toothbrushes. I have a brand I am happy with, and I use
them with a sense of loyalty. In the long run, I believe I have been
rewarded for this. This is the way I work. Dell has worked for me,
generally, and I know Dell, so I buy Dell.

Fifth, *most* people in the Linux community at home are not looking for
technical support fot Linux, they want to actually solve the problems
for themselves, and learn from it. In the case where Linux is installed
as a critical server in a business or other place, then I would
recommend a pre-configured, pre-installed, and professionally maintained
system with more critical / timeous / professional support than the
average (even *guru*) home user could provide.

Sorry about the long reply...  suddenly felt that my recommendation
needed defending ... ;-)

Hi Phil,

Could you elaborate a bit more on how you get Linux to treat
a DVD drive as a CD-ROM drive? I'm planning to buy a
Dell XPS R450 as well and would dearly like to be able to
do just that.

Many thanks.

Kar Lik.

Check to make sure they aren't sharing an IRQ.  I recall seeing posts like this
in the kernel group a few days ago.  You can fix the problem by shuffling the
cards around.  Also the experimental kernels have some support for sharing
IRQs, but I don't know if it helps in this case (note, you will need to update
some things to run an experimental kernel).

I had the very same problem (Diamond Viper 330 vs 3Com 3c905b).  The answer is to
use the XFree86 3.3.2.3 (the last .3 is crucial :> ) whose SVGA server supports
IRQ sharing.  It fixed my problem without my having to move any hardware or change
any interrupts (and the two boards still insist on sharing IRQ 11).

1. Serial port speed limit - Dell Dimension XPS R450

I've got an ugly serial port problem with my new Dell Dimension XPS
R450.  I start to get errors at 57600, and at 115200 it's so bad that
the effective data rate is down around 1k/sec or less.

After much cable and modem swapping to isolate the problem, it's
clearly within the new computer.  I'm still waiting for a callback
from Dell Tech Support as to whether or not the serial port is
supposed to be capable of 115200, which it really should be, since
Linux identifies it as a 16550A.  Using the same Linux distribution,
kernel and configuration my old 66Mhz Pentium easily and reliably does
115200.  (RedHat 5.1+ and a 2.0.35 kernel)

The port is configured at the standard COM1 address and irq, and there
don't seem to be any IRQ conflicts.  Using irqtune doesn't appear to
make any difference at all.

The next step is to use hdparm to allow unmasking other interupts in
the IDE driver, but I've never needed to do this with the older slower
machine before and I'm not sure it's safe with my controller and disk
combination.  Does anyone have any experience with the IDE controller
on the Intel SE440BX and the IBM 10.1Gb 7200 rpm UDMA HD?

Since I also want a second high speed serial port for the machine does
anyone know how the current stable kernels handle the TI 16750 UART?
I know that there are problems with the 16650 which is treated as a
16450 as a result, but even if the 16750 is just treated as a 16550A
the deeper FIFO could be a net gain in reliability...

It's really frustrating to get a new "fast" machine and find out it
won't communicate as fast as the old "slow" machine. 8-(

Thanks...
