HI,
i would like to know if someone have good
experience with a RPC1 SCSI DVD Drive and thus
could recomend it.
I'm looking for one but could not get enough info
to decide which one to buy.

Hi. Hate to be the one to report it, but I was just reading
a web site yesterday, which reports on compatibility of hardware
with Linux, and I was checking out the Abit BP6 because I wanted
to get one, with dual Celerons, of course.
Well, the nasty gotcha was, "If you run both CPUs at more than
85% of capacity simultaneously, then data corruption does occur.
It seems that the BP6 doesn't have quite enough front-side bus
"bandwidth" to run both CPUs at full utilization."
I was very sad to read that, and immediately decided to look
elsewhere for dual Celerons. (Alas, can't remember the URL,
but you should be able to find it with a web search.)
What you are reporting is exactly what he reported: have several
programs running, and max out both processors, and data corruption
occurs.

Nope. My laptop has its CD-ROM on /dev/hdb. It's like this:
/dev/hda master on primary IDE interface
/dev/hdb slave on primary IDE interface
/dev/hdc master on secondary IDE interface
/dev/hdd slave on secondary IDE interface
The original poster should make sure that the CD-ROM is jumpered
correctly. If it is plugged into the primary interface as a slave, it
should be jumpered as a slave. It it's plugged into the secondary
interface as a master, it should be jumpered as a master. Most CD-ROMs
seem to come from the factory jumpered as master. Also check the cable
connections and make sure they're tight, and make sure the IDE cable isn't
br0ken or longer than 45cm (18 inches). HTH,

1. Check in the BIOS for an option that says "Memory hole at 16M". This
should be NO; it was required for some really old DOS stuff, and Linux
doesn't play well with it set to YES.
2. See if there's a BIOS upgrade. Admittedly, this is a prototype, but
several other people have a similar problem with normal motherboards and
a BIOS upgrade fixed them.
3. Since this is a prototype, notify the engineers/whoever, tell them that
it's FUBAR under Linux, and suggest they fix it...

Subject: Problems with new memory module
Date: Wed, 05 Apr 2000 21:03:03 +0200
I've been running linux now for sveral years, but this is new to me:
The linux box I set up last year has the following setup
- 350 AMD K6-2
- Adaptec AIC-7871
- WINCO Motherboard with a VIA 82C586 Apollo Chipset
- 2 SCSI and 2 IDE Disks
- 64MB PC100 SDRAM
- SuSE 6.3 Linux with 2.2.13 Kernel
and it has been running like a dream. I had uptimes of several months,
and not a single crash. ( I rebooted only voluntarily )
The only drawback was the little memory. Since the prices for PC100 RAM
got acceptable again, I decided to buy another 128MB about 2 Weeks ago,
and that's when my trouble started.
I tried just about any combination of BIOS settings but the best I can
get seem to be about 2 Days of Uptime until my system hangs without any
message or obious reason.
Oddly enough the RAM seems to be OK, since I ran excessive tests on it
(I used ct-ram, a DOS-Tool specifically designed to detect memory
errors, lasting for several hours)
It also doesn't seem to be temperature-related as I bought an extra-fan
and the temerature has dropped several degrees as opposed to the time my
system was stable.
I haven't changed anything in my setup except the memory, so I'm
absolutely clueless.
Has anyone experienced similar problems?
Am I missing something obvious?
If anyone knows something else I can try, please drop a note. The only
solution I see is going back to 64MB of RAM and that is not really an
option to me...
Thx, Tobias

Hi, I just compiled 2.3.4 kernel and Promise seems to be working okay.
I'm curious though about the hda/hde issue. I selected "boot off-board
ide chips first" or some such. Also, since the motherboard ide is
doing the cdroms and floppy drive, am I better off to leave well enough
alone and let the hd be /dev/hde?? Things are working fine at the moment
and I booted diskettes and ran e2fsck, so it doesn't seem to be munging
my file system or anything, so I'll probably leave it as is, but I'm curious
to learn more(sorry for the stream-of-consciousness but I'm due for a coffee
I guess.) :)

And where is this from? I have built many things with make -j3 and both
processors close to 100% and never had a bad build of anything. I have
had lockups, which is another story altogether. BP6 has problems, but
this is not one of them in my experience.

I seriously doubt the validity of that article. I have a BP6 with both
processors over clocked from 400 to 570. I've run Linux on it and put a
full 100% load on both processors and never had any problems at all.
Admitedly the load was SETI@HOME so I can't say that I really tested this
claim but both processors were running at 100% and I never once had a
problem outside of a silly power supply rebooting the system once in a
while.

Dear:
FYI, you don't have to buy or use a external hard drive. There is one solution to
this. And that is also the method I am using right now. You can use regular
internal hard drive (as long as it works with Linux). All you need to get is
something called "Hard Drive Drawer" It has one inner case and one outer case.
The inner case holds your regular hard drive and the outer case fit into the 5
1/4 bay of your PC case.
The installation is really easy. As far as setting's concern, you can just treat
it as any internal HD. I have two HD run Linux and one runs Windows 98. When I
need to run Windows (sad), I just halt the Linux system and pull put the HD. Pop
in the HD that runs Windows and turn the power switch one.
The price of the "HD Drawer cost from about US$15- $35... Depends on where you
get it and the quality of it.
Hope this help.
Alex.

The way it works in Linux, is that the interrupt handler puts some bytes in the
'flip' buffer (sorry thats what it is called), see /usr/src/linux/kernel/
then do a grep flip
This buffer is rather small (and bound by a 1024 byte page size).
Now the scheduler comes around, every once in a while, to copy the 'flip'
buffer to wherever (see kernel sources again).
If time is to long, characters (bytes) are lost.

Right, Linux kernel DISABLES DMA by default, this due to problems with some chipssets
on multisector read in the driver (I suppose).
You can use hdparm to enable the DMA, or set the relevant multisector mode, PIO mode,
etc.
Chances are you mess up a harddisk, IF you had the wrong chipset (this is explained in
the
kernel docs) and happened to me, of cause I want to try how far i can go..

Yes, but it is not so simple.
If you are receiving data with a V90 at full speed from your ISP, the connection will

It is a very intersting subject, and experimenting makes you aware there is more
to it then you think.
Please also note, that frequent packet loss, if an error is not detected
(things like CRC are only so good, not better then 1 in 65536 I would say),
you may have your download, but the data could still be corrupted.
Not something I would want.

I really am curious as to the problem.
In thin air fans won't work to well. Hard drives with breather holes have
that same problem. But that doesn't explain the mother board or modem
failures. I mean those are just electrical devices with no moving parts to
air pressure shouldn't affect them (within normal pressure limits.) I
suppose they could be overheating but that doesn't sound right to me. Chips
fail because of excess heat LONG before boards do. Although neither the 286
or the low end 486 are big heat producers. I suppose that heat could be
coming into play but from my experiences when heat is an issue, the chips go
loopy, NOT the system boards.
The radiation thing is another one but the fact that your older machines
work fine says that it's not the problem. Also the fact that you don't have
monitors listed as having problems sort of rules that out.
Line problems with your power supplies doesn't sound real likely but even a
small UPS would take care of that. It won't keep your machines running on
battery for long but it will clean up the power to your systems.
Just curious where do you live? 10,000 feet above see level is awfully damn
high. Mount Everest is what 28,000 something feet high? You ever think
about coming down from on high to live with the rest of us lowland dwellers?
I honestly don't know what the problems would be caused by. Of the possible
options presented here I'd say heat is most likely, followed by the
radiation thing, and then the power line quality. My guess is that it's
going to be something to do with a combination of all of this.
The one overlooked possibility is the pressure equalization issues in the
chips on the boards. Most of those boards and chips are made in clean rooms
and are sealed with either plastic or porcelain. It's possible that there
is a little bit of air trapped in the chips. In the higher altitude that
air would try to expand causing some funky pressures inside of the chips.
I've seen where a small resistor being stratched by 1/100,000 of an inch
caused a 400V capacitor to overvolt to as high as 682V. I guess it would be
possible for the chips to wear really funky with that kind of pressure
problem. Of course this is all just conjecture and theory. I have no
experience or research to back it up but it is logically possible and could
possible be part of the problem.
Good luck.
