I'm going through the same process on my home system, with RedHat 6.2.
All of this is pretty much stock, right from the CD-RW How-To, except
for the "alias scsi_hostadapter ide-scsi" line. That one is missing
from the instructions.
Without that line, modprobes are needed to get the modules autoloaded.
With that line, it all works.
Unfortunately, once I started fiddling with building all of these
things as modules, it seems as if timing problems cropped up with
the IDE section of the MVP3 chipset on my motherboard. There would be
errors showing up in /var/log/messages, and in some instances the
system just wouldn't start up cleanly.
So I scratched all that, and built all of that stuff into the kernel,
instead of as modules. Not only are the timing problems gone, but
the CDROM is recognized under SCSI emulation at boot time. Even better,
Kudzu recognizes it during boot, and offers to configure for it.
(Probably amounts to moving the cdrom->hdac symlink to cdrom->scd0.)
A note for the road ahead...
I partitioned up 700MB of unused disk space, (Newly onto a larger
disk, so I haven't fully expanded into it, yet.) formatted it as
ext2, and tried to mount it as /tmp. I figuree that way it was usable
for other purposes besides CD images, and skulker would keep it clean
for me. Big mistake. There are boot sequence dependent issues with
trying to do that. It can be made to work, but not by simply changing
an entry in /etc/fstab.
OTOH, I've been assured that mkisofs can write to and cdrecord can
read from a raw partition, and that in fact, that's more reliable
and thus preferable to using a file in a filesystem. So I've put the
mount point for /mnt/cdimage in /etc/fstab, and set the fstype as
iso9660. That way I can directly mount the image to test it, though
loopback isn't really an issue. I have not yet tested this, but will
get to it, soon.

1. Enter the line
alias scsi_hostadapter ide-scsi
in /etc/conf.modules
2. Create an init root dir with
mkinitrd --image-version /boot/initrd 2.2.14-5.0
(or replace 2.2.14-5.0 with the kernel version you're using)
NOTE: Must run intrd only *after* doing step 1.
3. Include the lines

initrd = /boot/initrd-2.2.14-5.0
in lilo.conf entry for the kernel and run lilo
this has worked for me (and collegues) on several occasions.

Date: Thu, 13 Jul 2000 10:08:15 -0500
Hey, gang!
I'm having some install/configuration problems, and was wondering if
anyone out there might be able to help.
I'm trying to install Linux (I've tried the most current versions of
both Red Hat and Debian) on a kludged-together box. It's a 450MHz
Celeron processor on a MS-6182 Motherboard. It's the motherboard that
is the problem.
I'd like to set up X, but in order to do so I need answers to a few
questions. Questions like, "How much video RAM does it have?" I've
scoured the manuals, as well as the Micro Star International web site to
get more info for this puppy. All that they say about the video is that
video is a GMCH chipset integrated with the board with "onboard 4MB
Display Cache (optional)."
I can't tell if the 4MB display cache is there or not.
As I said, I'm having a deuce of a time setting up X without the ability
to answer this question, and there doesn't seem to be any way to ask MSI
this directly (and no mention of anything useful on the web site).
So would any of you know if there is Linux support for this board?
Any ideas?
Grateful for whatever bones you might be able to toss my way,
Chris

telnet will work; there may be better solutions like an X server for NT.
I've four machines next to each other and use a 4-way

this is highly dependent upon the layout of your playroom.
One thing that I'll throw out is a UPS -- I cannot say how many times

I have yet to see any reports, positive or negative, about USB DSL
modems in Linux. If they can be made to work at all, you'll need a
2.3.x/pre-2.4 kernel, or the USB code from one of these kernels patched
into a 2.2.x kernel. Check http://www.linux-usb.org for details. The
compatibility list on that site doesn't list any USB DSL modems, but it
does list at least one ISDN adapter as supported, and at least one
USB-to-Ethernet adapter, so there's at least a possibility that a DSL
modem will work. If it does (or doesn't, for that matter), please post
details to the group and add your information to the USB compatibility
database.
If it doesn't work, you may be able to exchange your modem for an
Ethernet-interfaced device, which is the usual way to hook up to a DSL
system from Linux. If you're desperate enough, you might even try buying
a used DSL modem from eBay or the like. If you then sell your USB DSL
modem, the net cost might be very low.

Oooh! I forgot about that! Yes. A UPS is always a good thing.
I spent a bit of money on mine and got an APC BackUPS Pro 1400. 1400VA
is a pretty hefty UPS, but it's enough that I can remain operational
(with the monitor) for 90 minutes. Longer with the monitor turned off.

I've used dual CPU boards for quite a long time. The bottom line is the
machine's performance under heavy loads caused by multiple processes.
Two CPUs can slog through multiple requests better than one; the
difference is tremendous.
As an example, the machine that I'm on right now is a dual P-II/400
development server running RedHat 6.2. RH auto-detects the multiple CPUs
during install, so no fussing is needed. It has three SCSI disks running
RAID-5 out of the kernel.
If I have a program that is burning up 100% of one CPU, the other CPU
can handle the ordinary things, such as computing RAID-5 checksums,
interrupts, etc. In truth these get split up between the two processors,
but the net effect is the same: I can load down the machine and the
machine is still snappy.
Running both CPUs full-bore with an in-house program that keeps two
threads fully busy, I typically see about an 80% increase in throughput
under NT and 90+% increase under Linux on several different setups (YMMV
of course). You'll not get 100% boost because of hardware and software
overhead.
> What about dual Pentium III 600Mhz vs single Pentium III 600Mhz?
Depends on your use. As a workstation, it probably won't have any real
effect unless you're deliberately pushing the machine real hard.
> Does Win98 / NT support dual processors properly? What about Linux?
No / yes. Very well.

The speed that electrical signal travel through copper wire is slower

There is actually a bottom temperature for CPU. The temperature is -273
DEG C. The super-conductor computer is running near this temperature.
The -40 DEG C is only the atmospheric temperature. The temperature of the
chip may be as high as 100 DEG c.

That's how I built mine - with spare parts.
A firewall still needs to be configured properly, but it's easier to
secure a network from a single point, than to have to keep all your
workstations secure.
On my network, the firewall rejects all incoming TCP connection
attempts. (Actually, it just discards those packets without sending
back a "connection refused" packet.) Since I'm not running any
publicly-accessible servers, this works fine. (Note, however, that some
apps - like FTP and RealPlayer may require some massaging to work from
behind a firewall that's rejects all connections.)

NT includes a telnet app which will work.
Personally, I don't like the telnet app that Microsoft ships, so I
downloaded a different one. It's called "TeraTerm Pro". You should be
able to download it from TuCows and other sites.
Ordinarily, I recommend against doing maintenance through an unencrypted
telnet session, but if your LAN is behind a firewall, you can probably
trust everybody connected to it :-)

If you start shopping around different vendors, visiting local mom-n-pop
computer stores, and attending computer flea markets, you'll find that
there are over a hundred different kinds of cases to choose from. They
come in all sizes, shapes, colors and prices.
The most important thing is that it fits your motherboard. Motherboards
today come in two form factors - AT and ATX.
ATX is the new style - you can identify it by lots of built-in I/O ports
PS/2-style keyboard and mouse, USB, two serial, parallel, joystick/MIDI
and sound are the commonly found ones. I've also seen them with video
and Ethernet on the back panel. ATX cases are designed for all these
ports and include cutouts where the ports all go. The panel containing
these cutouts is removable so that it can be replaced - ATX motherboards
with a non-standard layout will include a replacement panel.
AT motherboards, on the other hand, have only one built-in port - the
keyboard. All other on-board devices have connectors at the end of
cables. These connectors must be attached to slot-cover brackets or to
knockouts in the case.
AT and ATX are not interchangeable. An AT motherboard will not fit into
an ATX case (although there are some exceptions) and an an ATX
motherboard will not fit into an AT case.
If you are buying both case and motherboard, I'd recommend ATX. In
addition to the convenience of the built-in ports, ATX offers a number
of other useful features:
- better cooling. A proper ATX case will have the power
supply's fan blowing air over the CPU.
- Soft power. ATX boards support software power-off.
- Many ATX boads also support suspend/sleep modes, wake-on-LAN,
and other useful power-management features.

Subject: ISDN Card problems with WINBOND w6692 chip
Date: Thu, 13 Jul 2000 18:01:06 +0200
Reply-To: [EMAIL PROTECTED]
Hello,
I've got RH 6.2 with GNOME running on an INTEL 166Mhz, which runs just
fine.
Next I want to install an ISDN card and I've got problems.
The ISDN card is a Accex passive PCI card with a WINBOND w6692 chip.
isdn4k-utils and insdn-conf can work with these cards according the
manual, this with the HiSax.o driver.
After installation 'kudzu won't recognice the card. It looks like the
system can't work with it.
The function 'lspci -v' recogize the card afterall with the following
output:
-Class: 0080
-IRQ 9
-Memory at f5eef000
-I/O ports at d000
-Flags: fast devsel
-Unkown device 5478 --this can be true, because it's not listed in
'/usr/share/pci.ids'.
The file '/proc/pci' recognizes the card also, only with more output
'Bus 0, device 10, function 0', and 'Unkown Class'.
This looks strange because "lspci -v' gives Class: 0080 .
'lsdev' does not list the card, there is no IRQ 9 in the output.
This is also in the output of 'procinfo'.
How do I solve this, can I force an IRQ setting with 'setpci' or is this
end of story.
Could somebody give me an example of the 'setpci' instruction.
Thanks,
Hans van Leest
