Quite possible as this is a quite heavily loaded system what comes to
power. The voltages were checked when mounting this drive though and did
seem to be good. I don't know, though, how strict this drive is in
comparison to others.
Thanks a lot for your suggestions, I'll get back to this when I have got

Hi,
Has anyone been able to make an Maudio(Midiman) Delta44, 66, 1010 card to
work under RH or Mandrake. I am using Mandrake 7.1 and Kudzu found and
configured the card. It has its own IRQ, when booting the sound module
loads fine (ICE1712). The card shows up the alsa section under
/proc/asound. It seems that the devices can not see the card. Also,
sndconfig says it can not locate the card as well as HardDrake shows nothing
under soundcard.

Try the -ignsize option? Read the man page, though... really, cdrecord
should let you write a 700M image so long as there's space on the
medium. The CD-RW has to support writing data CDs that are over 650M,
but just about all of them do.

-c1 instead of -c3 will improve performance a tad. There's a lot of
ambiguity wrt hdparm because there are a lot of different chipsets and a
lot of different drives, and the IDE driver changes every so often.

Umm...where have you been for the past year? Back when the K7 first
appeared, its FPU outran the P!!!'s by about 40% on most benchmarks. Intel
closed the gap somewhat when the CuMine P!!! appeared, but most of the
improvement there was from the on-die L2 cache...a feature now present in
the latest iteration of the K7 (Thunderbird). I think it's also worth
mentioning that AMD is having no problems shipping fast (>950-MHz)
processors, while Intel is running into all sorts of difficulties getting
its processors to run reliably at such speeds.

When I upgraded to 2.2.16, I cannot boot machine without

It says: 'hdd: lost interrupt' over and over.
Worked fine with same ppm support compiled into kernel

An ATA/66 drive will also work well if there's nothing else on that
channel. The problem here is that the stock 2.2 kernels don't support
ATA/66, and you probably don't want to run prerelease code on a
production server.
For best performance, I'd recommend an Ultra2 SCSI drive and U2
controller.

Multiple smaller drives (if left as separate volumes, not as an array)
will give better performance if your server is subject to a large number
of simultaneous hits. Multiple independant head assemblies can access
multiple files simultaneously, whereas a single drive can only access
one file at a time.
The difference is usually noticed for applications where large numbers
of small hits are encountered - like a large news server. Less so for a
web server. You probably won't notice much difference for batch-
oriented servers, like e-mail.
Of course, you really need SCSI for this. ATAPI doesn't allow two
drives on a single channel to be accessed simultaneously.

Yes. Definitely.

Receiving e-mail (SMTP) doesn't need much horsepower. Mail Transfer
Agents (MTAs) are designed to hold onto mail messages and periodically
resend them if the next-hop serveris busy. Unless your mail server is
very slow (or your load is very high), the incoming messages will back
up and get delivered later during periods of congestion. The main
reason a mail server needs horsepower is when handling e-mail floods -
like when some spammer decides to send you a million messages to a
million bogus addresses, causing legitimate mail to get seriously
delayed.
POP3 must respond a much quicker than this. Users don't want to wait
long between when they request mail and when they start receiving it.
Based only on my own annoyance levels, I would say that a POP3 server
should start returning messages within 20-30 seconds of a request from a
user. Preferably much faster, but that's about the point (I think)
where users will get frustrated, disconnect, and start complaining to
you.
Web pages (including webmail) must also respond reasonably quickly. If
a user waits more than about 5-10 seconds for a response, he's going to
get frustrated and start complaining to you. Be sure to keep the
bandwidth of each page low (by not going overboard in your use of images
and applets) unless you're certain that your users have fast enough
links to receive it all quickly.
One more thing. If you run a web server, it is going to get hits from
people other than your customers. If someone puts up a page that
becomes popular, the number of hits can swamp your server and your
network connection. Some ISPs solve this by rate-limiting the web
server, and some solve it by charging customers if their page uses
bandwidth in excess of some threshhold.
You can't do much about the bandwidth other than buying more or
rate-limiting the server. You can, however, keep a swamped web server
from taking down your other services. I recommend running your web
server on a different physical computer from your e-mail server.

They should all work reasonably well. I think the Duron/600 will
outperform a K6-2/550. But the motherboard will cost a little more.
As others have said, I/O is going to be your primary bottleneck here.
This means you need lots of RAM (at least 128M), a fast disk or disk
array (I'd recommend Ultra2 SCSI if you can afford it), and a fast
internet connection.
Note that your overall bottleneck will probably be your connection to
the internet, and not your computer. A T1 line (or equivalent DSL line)
is 1.5Mbps in each direction. Significantly slower than a 10M or 100M
Ethernet interface. Faster network connections, of course, are
available, but they will cost more.
It's been my experience that a reasonably modern PC (like what you've
proposed) running Linux will have no problems serving files to the limit
of a 10M Ethernet interface. Considering that 10Mbps and faster
internet connections are pretty expensive, you should be OK.

Haven't actually used a Duron, but the reviews I've read (Tom's Hardware
Guide) seem to be favorable.
I think you need to spend your money on RAM, disk, and I/O bandwidth.
Even if this means a slower processor. Unless you are running some kind
of compute-intensive CGI programs on your web pages, your overall system
will be I/O bound (on network and disk) and not CPU-bound.

Thanks for your reply. What I am actually trying to do is, start a small
ISP in a small country town which at present only has ISDN available for
a fast connection to the internet. I admit I'm not familiar with ISDN
and the new cards which are out. I have found a card which has 24
digital modems for the dial-in connections so now what I am looking for
is a ISDN PRI/T1 capable card or modem that I can increase bandwidth for
future growth when needed. I ran accross www.spellcast.com which has a
dual ISDN PRI/T1 card and am waiting to hear from them on it.
Any help on hardware to start an ISP would be appreciated.
Thanks.

Subject: Re: Linksys LNE100TX v4 won't initialise under RedHat 6.2
Date: Fri, 11 Aug 2000 13:48:00 -0500
The only way I can get the linksys LNE100TX card to work on my systems
is to compile the module on the system.
To compile the module you will need to log in as "root", or "su" to
root.
You can download the latest version of the Tulip.c driver from one of
the links below, or copy it from the Linksys disk that came with the
ethernet card:
http://www.linksys.com/support/support.asp?spid=25
ftp://ftp.scydld.com/pub/network/tulip.c
Next you need to add a directory named "inet" to /usr/src/linux/net
with the following command:
mkdir /usr/src/linux/net/inet
Then copy the tulip.c module into the inet directory with this:
cp /path/to/tulip.c /usr/src/linux/net/inet/
First you remove the old module.
rm -f /lib/modules/kernel_version/net/tulip.o
In order to be able to compile the module you need to be in the inet
directory. This can be done with the following command.
cd /usr/src/linux/net/inet
Use one of the commands below depending on what is needed by your
system.
Be careful of typo errors, they will cause the compile to fail.
1.) To compile the Tulip module, issue the command below, it must all be
on one line:
gcc -DMODULE -D__KERNEL__ -I/usr/src/linux/net/inet -Wall
-Wstrict-prototypes -O6 -c tulip.c `[ -f
/usr/include/linux/modversions.h ] && echo -DMODVERSIONS`
2.) For a dual processor system, compile it with the command below, it
must all be on one line:
gcc -D__SMP__ -DMODULE -D__KERNEL__ -I/usr/src/linux/net/inet -Wall
-Wstrict-prototypes -O6 -c tulip.c `[ -f
/usr/include/linux/modversions.h ] && echo -DMODVERSIONS`
Once compiled you need to install it as follows:
To install the new
cp tulip.o /lib/modules/kernel_version/net
You need to add the "tulip" module to /etc/conf.modules using the
correct device (eth0, eth1, etc...).
alias eth0 tulip
Now update the "modules.dep" file by issuing the following command:
depmod -a
>From this point most of the time all that is needed is to restart the
network for the new module to be activated. You can do this with the
following:
/etc/rc.d/init.d/network restart
If you want to check it prior to restarting the network, you can issue
the command below and then check /var/log/messages for any errors.
modprobe tulip.o
The the module is installed correctly, if no errors appear in the logs.
If you tested the install you need to unload it from the kernel with the
command and then restart the network:
rmmod tulip.o
