You can also run cdrecord --scanbus after you have things set up. HEre is
what a box does that I have when I run that command. This is on a 2.4.5
kernel... So it works fine there too-

Have you considered the Toronto models of the thinkpads? Pretty nice with
fast processors, a bit lighter than the Monaco, and a bit nicer in the
weight department. The A20m is a generation old also. There are new
Monacos either out or soon. If you check IBM's laptop preloads, I believe
you will see that the Toronto now comes preloaded with Linux on it. I have
also used a few different Dell laptops and have been pretty happy with them
including the Latitude Ls, the Inspiron 7000 and up, and one other Latitude
model, perhaps the Cpx. If you want to take a look at some certification
reports, Linuxcare certifies laptops for Dell and IBM. Its a good way of
comparison shopping for what does what. Check out the tab off their website
which says Labs and then to the reports.

Nice question... Sure to get lots of interesting posts and beliefs and ideas
:) Here is a one I am sold on lately:
*AMD Thunderbird 1g with a Soyo Motherboard KT133, floppy drive in mid-case
(available as a barebones system)
*512mb of PC133 memory on one, the other has 384mb of memory
*GeForce 2mx 32mb card on one; Diamond Viper 770d on the other
*Twin Maxtor 40g ide drives (nice and cheap; both less than $300)
One is completely ide; other has a 2940 card I use for backups, zip drive,
etc. I purchased two cards off of ebay so I use them as I can.
*One 50x cd and one has a HP 9300 cdrw (ide) in it
*SBlive soundcard with the OSS commercial drivers (Im a wuss with sound)
*Intel EtherExpress 100+ cards (I get these really cheap in the OEM version)
Then I download the floppy images for debian potato, blast it on there,
immediately edit /etc/apt/sources.list to bring it to unstable. Download
the 2.4.5 kernel, get the AMD compile options, get mtrr and ide support for
dma in the kernel. I also download the latest nvidia GLX and kernel
drivers.
Makes for a nice all round system. Also plays some games from Loki pretty
nice with lotsa free disk space. If you would like some urls I have for the
hardware, let me know. I either buy barebones systems from one vendor these
days that I know from a lot of purchases, or I buy everything separate and
build it.
ImO, AMD is the way to go! Linux likes these systems too. The only issue I
really had was under the 2.2.x kernels. Moving to 2.4.x had really given me
better performance, speed, stability, etc. I also want the systems to get to
X4 as quick as possible so I can use the nvidia drivers.
So, if you want good systems, to me, go with AMD.

Or, it may be
- a "Plug'n'Play" modem (which IIRC aren't well supported under Linux),
or
- an ISA 'WinModem' which needs a manufacturer-supplied software driver
(actually a DSP-in-software) to work.

Make sure you figure out if that's 50 users sending small text-based
messages or 50 middle-managers mailing 1.5MB powerpoint presentations
incessantly. If it's the latter, make sure you've got plenty of disk.

SWAT (Samba Web Admin Tool) makes this real easy. Note that Samba 2.0.*

Well, if you want to rack-mount it, it's going to matter. Other than
that, just make sure you have room for the disks. I say this because I
spent two days fighting disks into a 4U. Oddly, it looks like our 2U's
have more room for disks, and better cooling *shrug.*

256 should be fine to start with. If you need more, you can always run to

Cheap IDE. You should be able to pull off 120GB of disk for < $500. Run
RAID5, and you've got 80GB of failure-protected disk. [Depending on you
file serving needs, you can go higher or lower for not too much price
difference]
> d) Other -
Possibly a Promise or HighPoint PCI IDE controller. Both of these may
require a kernel recompile, and possible patching, though.
I'd recommend software RAID. It works well, can be used on partitions as
well as disks, and costs much less than a $500 RAID card.
Make sure your IDE disks run in ATA-66 or better modes. Make sure you
have the IDE cables to support that.

If you have lilo 21-3 or newer, try adding option lba32.
If not, get the latest version of lilo.
You might want to take a look at grub which is another
nice loader program.

I've the opposite problem.
My Asus CUV4X has not the AC97 on board (it's optional in my model)
but i see the system trying to hang this module!
What can i do?
(in BIOS i've disabled the audio system already).
Thanks!

I have to say that I have been somewhat disappointed with my new 1GHz
Thunderbird under the 2.2.16 kernel. There have been no problems of
instability, but I have not realised the speed gain I anticipated.
Calculations involving large arrays and floating point operations
take six hours to complete. The same jobs take ten hours on my
old 200MHz Pentium Pro with 512K L2 cache. This is not a graphics
application, and disc usage is minimal.
I compiled by own kernel on both machines, but I do not really know
how to optimise for the Thunderbird.
Does the 2.4 kernel series really make such a difference?

I am thinking about replacing my Dual BX board with another. I was
looking at a mobo that has the ServerWorks ServerSet III LE chipset.
It has a lot of the features that I like and seems to be pretty
upscale. I have not heard much directly about this chipset, but
noticed that all boards with it are pretty expensive.
Can anyone tell me about this chipset and how it acts under linux?
Thanks!

It looks like your application is limited by memory bandwidth and
latency, rather than CPU speed. The Pentium Pro is probably using RAM
with a 66MHz bus, and the Athlon 100MHz or 133MHz (depending on
chipset, CPU version, and BIOS settings). For a rough guess, the
133MHz bus would cut the time in half. Then throw in the benefit of a
larger cache for the Pentium Pro, and the times you report make sense.
You'd likely see improvement with a DDR SDRAM motherboard for the
Athlon, and with future Athlons with larger caches. A RDRAM P4 would
also speed things up, but at a considerable price. The factor to look
at is the motherboard chipset and RAM technology, because that's
what's driving the memory bandwidth. It's been decades since anyone
made a processor that was slower than the memory.
CPU speed gets more attention than it should. Memory, graphics, and
disk are just as important in system performance.

I am running RedHat 7.1 right now and would like to install a modem in my
system so that I can get connected to the Internet. I was wondering if
anyone had any ideas what modems are compatable with Linux.
Right now I have a Sportster 56k Voice Faxmodem (ISA) installed in my
windows PC. Does Linux support this modem and what would be the procedure
of installing it or what might be the problems that I will face using this
modem with Linux. I havent been able to find any support or information on

Subject: Servers and energy saving?
Date: 9 Jun 2001 08:02:36 -0700
Hi,
With the power problems that have been happening recently the
company I am working for is looking at different approaches to save
energy. The workstations we have concluded can easily be shutdown at
night and on week-ends, or put into sleep mode. Most of the printers
have auto-shut-off if they aren't used for a certain amount of time.
Now the servers a little more trickey. I know that it is bad to send a
server
into sleep mode because of the hard-drives, so I was wondering whether
there are any servers that can either drop down to a lower clock-cycle
if they aren't accessed during certain times or sleep if not accessed,
but
still leave the hard-drives running?
If anyone has come up with an energy saving plan that works for all
their computers I would love to hear about it - I am sure someone in
Calafornia has got this problem sorted.
