Sorry, but I don't know much about hardware, so maybe my following question
is absurd. Isn't the cable a part of the monitor? I think it is fixed to it
when shipped to me, then how can I change it?
Another question is I can run Win98 on my machine quite well(without these
blurs), but screen will keep blinking during Win98 startup, and a lot of DOS
graphic applications will cause the screen to blink incessantly and so can't
be used. Is this also caused by the cable? Then why doesn't Win98 show blurs?
Thank you!

here's my problem: the video is on the mobo and since its too close to
the scsi system, whenever I do lots of disk i/o, the video 'squiggles'
quite a bit.
having the video on a separate card means you can move it to a diff

I don't have the figures handy (I lost them and never reconstructed my

player and video card dell was pushing on us (for business you never
need dvd - sigh).
I also wanted a real 3 button logitech mouse and a second video
card/monitor. oh and no M$ tax.
add in hardware raid, dual cpu and a few drives and there was more
throwaway stuff on the dell than keepers.
granted, my config was very hi-end and not at all typical, but still,
I HATE throwaway hardware.
oh, yes, and the modem was obviously a throwaway too. you can guess why ;-)

Date: Thu, 20 May 1999 15:11:32 GMT
if you build in parallel (the kernel is the best example I know of)
then you will benefit from multiple cpu's. I believe in it - I built
3 dual-celeron systems and love them! ;-)
some makefiles aren't so SMP friendly. you may have to do a "make -k"
a few times until all things are built.
if you work on different projects (or have 2 people accessing your
box) the dual cpu is a good system.
for true single-user stuff, go with a single cpu.
for daemons, cron jobs, lots of bg processes, go dual.
the dual celeron (300a o/c to 450) is still the best deal out there.
even if you have to use slotkets to achieve it.

A full tar is 10--20MB in size. A gzipped patch is just a few hundred
Kbytes in size (or even smaller). When you're download it through the
wire, paying a certain amount of money per second of download time,
that can make a huge difference.
Peter> Can I apply the 2.2.9 patch to 2.2.5 ?
No. patch-2.2.9 is supposed to be applied on source-2.2.8. To get
source-2.2.8, you may apply patch-2.2.8 to source-2.2.7. And so on.
If you already have the source code for 2.2.5, you can apply the
patches in this order:
patch-2.2.6, patch-2.2.7, patch-2.2.8, patch-2.2.9
I did it this way, and it works fine. The source code is too large so
that I burned it onto a CD-R (together with lots of other stuff to
exploit the entire capacity) and brought it home to use it on my home
PC. At that time, the most recent kernel was 2.2.5. Now, the newest
kernel is 2.2.9. Instead of transfering a 10 MB tarball to my home
machine through modem or burning another CD-R, I downloaded the
patches (which fit in 2 floppy disks) and brought the patches home. I
applied the patches one by one, and volia the source of 2.2.9.
Peter> If not, where do I find the source for 2.2.5 ?
You mentioned RPM. If you're using Red Hat 6.0, the source code for
2.2.5 is in one of the RPM's.
BTW, the source code that comes with Red Hat 6.0 seems to be modified
(by Red Hat to add its own features), and hence the patch files would
fail. Using an intact source tree, the patch files all apply
successfully without any errors.

Most distros have a version of 'powerd' somewhere which might do the
job. However, watch out for intelligent UPSs - I've got one that
doesn't support Linux (a small box from Alpha - they claim that Linux
support is available RSN at $100 Au.)

I had problems with my tape also and saw a boot time message "module st
not found"
when I checked it was supposed to be built in to the kernel so I just
rebuilt the kernel and put the "scsi tape" part as a module now it works
fine. But it was installed this way from the cd so it could be worth
checking and by the way the device st was present before I rebuilt
anything. I figured it was due to my initio scsi card.
Well I hope that helped.

Some monitors have integral cables and some don't.
If you've seen the "shadows" be absent when the video
is setup by any other OS, then signal reflections are
probably not the problem.

Because Win98 is using a more carefully chosen
clock frequency, selected to avoid the instability.
I don't know what blinking you're talking about.

A slight adjustment of the clock frequency (3rd
field in "Modeline" lines written with a decimal
point) for the selected mode would be worth
trying. Adjusting it either way, by up to 1% or
so, can eliminate one source of blur which is
due to instability at particular frequencies.

That comment was predicated on "(if accurately
described ...)". If your shadows are more like
horizontal fuzziness than like "a shifted, faint
replica", then adjusting the clock is a good bet.

Others have already put forward this information, but I'll add to it. I
just last night set up a dual celeron system. It's pretty sweet. It's
not so dangerous or scarey as some people would have you believe (with
all the PPGA -> slot 1 converters out there, you don't have to short any
pins or cut any traces)... but it also might not be for you.
You're requesting info about building a number crunching system... I'm
almost positive that you could expect a significant performance hit be-
cause of the decreased cache size if you chose celerons instead of true
P-II's (celerons have 128K cache, true P-II's have 512K).

Miniscule... mainly because the CPU running your special task won't have
to switch out to run the OS housekeeping tasks... I'd think *maybe* a
2% to 5% difference in performance assuming your system is otherwise
idle. If your system is running some other processor-intensive jobs,
you'll definitely notice a speed up.

If you're not going to use the machine for gaming, then you'd be throwing
away your money if you bought a P-III 500. The only real attractive fea-
ture they have are the new SIMD (I think intel calls it SSE?) instructions
which are only good for games (currently).
Assuming the machine will only be used only for number crunching, I would
recommend a dual system over a single every time.

www.pricewatch.com is where I shop. They don't sell anything, they only
give a list of competing prices from other places that sell.

Subject: Cyrix CPU - Problems???
Date: 21 May 1999 04:42:22 GMT
Greetings
Want to build a linux learning platform out of spare parts from past
upgrades.
Suspect the more common (and slightly older) the components I use, the
fewer HW problems I'll run into (better chance of more developed drivers
etc). But I haven't seen any comments one way or the other about using
Cyrix cpus with Linux. Anyone have any comments about using Cyrix cpus to
run linux? Thanks in advance.
My proposed system - pretty basic stuff, never had problems with W-95
cpu - Cyrix P166 (non MMX)
MB - generic w/ Intel VX chipset
Video - generic 2d/3d - uses S3 dx chips, 4MB ram
Ram - 32 MB, 72 pin SIMMS
HD - Western Digital 3.2GB
CD-Rom - Sony 2x ATAPI
Sound - Creative labs 8bit SB

Subject: Question Urgent: Server Configuration?
Date: Thu, 20 May 1999 21:26:53 +0530
Hi,
I am to do a server sizing study as well a TCO (Total Cost of Ownership)
study & other related stuffs, for our client's network. One of them will be
setting up a 1000 user network and another a 327 user network, both
supported by LAN & WAN implementing TCP/IP protocol. The network is
heterogeneous having HP UNIX, Windows NT and Windows 95.
I am supposed to find out the requirements for 4 distinct servers (m/c s) in
each case. They will be
A. Firewall Server
B. DHCP Server
C. Proxy Server
D. Authentication Server.
I am currently planning them for UNIX and WinNT, but I have a distinct
feeling that LINUX will be a better option (lower TCO maybe?). But I am not
sure of the server configuration requirements.
I am not familiar with LINUX, and would be grateful if somebody can help me
out. I have certain query, specially in.
1. What should be the minimum tpmC rating of the server?
2. What would be the memory requirements (RAM)?
3. What would be Hard disk capacity requirements?
4. What are the softwares available for the following? (and in your opinion
which will be the best option?)
a. Firewall
b. for DHCP Server
c. Proxy
d. for Authentication Server
Guess I will have to learn LINUX fast if clients decide to go for it.
I kind of need it urgently as the deadline is only 9 hours away. I will be
checking the newsgroup hourly.
TIA.
Amitabh
PS: Don't mind, I have posted the query to multiple newsgroup, but wanted to
increase chance of getting quick reply( and was not sure exactly where to
post it to).
