There were problems with early generation K6 233s (and perhaps slower),
but these were fixed pretty quickly.  I've been running a home server on a
K6 233 for a couple of years now and have experienced 50+ day uptimes with
a moderate load (only quelled by power failures).  I also run a K6-2 350
on one of my machines and it's been flawless as well.

For the money, they're an excellent CPU and a decent performer.

Hi there,

Update your System.map by copying the new generated System.map,
There should be a `new one' waiting for you after compiling your

Subject: Tape question
Date: 20 Jun 1999 11:48:45 +1000

I have an Exabyte Eagle NS8 tape drive, with some Travan tapes.
After using a tape a *little* while, when reading from the tape
I get I/O errors and /var/log/messages has the following message:

Jun 14 21:50:42 tade kernel: st0: Error with sense data: Current 
                             error st09:00: sense key Medium Error 
Jun 14 21:50:42 tade kernel: Additional sense indicates Unrecovered read error 

Since I'd like to use this drive and the tapes for system backup 
purposes, a tape going unusable after about 20 rewrite cycles doesn't 
give me much faith ...

The tape was not mishandled, touched, dropped, magnetised, whatever.
Actually when it broke it was sitting in the drive, which read its
previous content (success), wrote new one (success) and tried to
verify it (error). The tape is completely unusable now.
 
Are tapes indeed that unreliable or I have bad luck with this
particular tape ?

Thanks,

Zoltan

Hey, 

I'm looking to buy a SCSI HDD and CDR or CDRW. I'll be running Mandrake Linux
on it. Anyway, this is my first foray into the world of SCSI. Can someone
recommend a HDD/CDRW/Adaptor setup? Maybe a few options? 

HDD: either 4 to 9 gigs
CDR/W: at least 4 speed write, i don't care about read.

And of course, I'm not loaded, so stuff that is inexpensive but good are 
good choices for me.

I feel bad that you wasted your time on my question, and I'll reconsider
my posting habits, but don't get your hopes up.  I'm not sorry that I
am not against address munging and will definitely continue that.  I
shouldn't have to explain the many obvious reasons.  I've tried putting

my messages, but I haven't yet come up with wording that doesn't sound 
kinda rude.  Perhaps leaving it out is ruder.  I'll think about it.

I do think people would know better than to send mail to
[EMAIL PROTECTED] though.  Everybody is supposed to know that "nobody"

reserved for textbook examples, etc.  That is, it should be obvious
that it is not a real email address.

BTW, when people ask for an e-mail response in NG messeges, I consider
THAT rude and almost never respond in any way. I don't like e-mail.

Your problems were presumably due to the poor support for the MVP3 chipset

Re-read the post; we tried two chips.  They were 333MHz K6-2
chips, and we were running them at 66MHz x 5.  Locally, all we
could find were VIA-based mainboards (San Bernardino, CA area).
Mail-order wasn't an option for a variety of reasons (school
policy being chief among them).

Never said that it was.  (Well, okay, re-reading the post, it 
was unintentionally implied...)  Rather, AMD chips are 
dependent on generally flaky and usually at least slightly
incompatible Taiwanese chipsets on so-called "super7" motherboards.
Our 100MHz K5 (i430VX chipset) is the most reliable box we run.
But note the chipset supporting it...

I use tape (DAT, DDS-2, 2 gigs per 4mm tape). I got a pretty good deal
on an HP surestore DAT drive last year, and although those are still
more expensive than other tape solutions (like Travan) the tapes 
themselves are a lot cheaper than tapes for most other tape drives
are ($5-6 each, as compared to as high as $50 for some tapes I've
seen). So that is also something to consider.

At present, I only have enough disk space to fill up one 2gig cartridge
if I do a full backup, so it works out fine. If I needed more, I suppose
I could swap tapes, and I've got enough tapes presently to handle 20
gigs worth of data. But I don't think I'd want to use CD-RW either
way. Even though the media cost is attractive (.99 per CD) you can
only write once to it, and if you have a lot of data to back up, then
you just spent a lot of money on blank CDs that have realistically
little value. And, if you want to rewrite on CD's, the cost skyrockets
to approximately $20 per CD, which really isn't justifiable IMHO 
concerning the amount of data that can be put on there.

Date: Sun, 20 Jun 1999 01:54:06 -0400

Well, I was finally able to get a serial console up and running.  Many
thanks to the people who provided me with help.  In any case - I've got a
crossover cable going from Com2 on NT to ttyS1 on Linux and logging in to
Linux via a term emulator called CRT.

The setup is a fresh install of SuSE 6.1 - Nothing tweaked...yet :)

As I don't have a network set up yet, I tried to do rz and sz using the
serial cable.  It's connected at 115200baud, but if I try to do a rz
(Zmodem) upload to the linux box, it is EXTREMELY slow - i.e. 200bytes/sec
and constantly decreasing.  However, if I do an sz <filename> from Linux, it
transfers at up to 11Kb/sec.  Why such a drastic slowdown with rz (Zmodem).
Does sz use a different default protocol?  And if so, is there a way to call
rz from Linux?  Because it's being done now by a menu command in CRT which
allows me to select files to upload to the linux box.  Thanks for any tips
again.

True, but it's really more complicated than that. A linux system doing
something like compiling the kernel is likely going to be pushing 
hardware a lot farther (and consequently may show negative effects of
overclocking) than a typical Windows machine will. In situations
like this, the idling really doesn't help.

Even a linux machine not doing much other than running a few programs
in X or what have you may look like it could tolerate overclocking OK, but
will just flop over with a segmentation fault when trying to compile
the kernel. That's what I observed when I attempted early on to overclock
my current P-100 to 133.

Compiling is more complicated than just "integer instructions". A perhaps
better example would be f.e., doing exact integer arithmetic, like computing
256K raised to the 256K power exactly (using bc). On my P-100, it took the
better part of a day. Compilation may be harder on the Intel - especially
optimization, due to the restricted register set. On the other hand, Alpha
has more registers, but it also is a RISC chip, and requires more instructions
to do the same task by comparison.

Alpha is perhaps better at integer (as well as FP) than Intel, since it can
superpipeline (stage more than one instruction/cycle) better than the
Intel can. But the PII (and perhaps PIII) can do this as well, and so can
the regular Pentium, although not as well. In particular, the Pentium's
scheduling is hampered in that some instructions can only be paired with
other instructions; otherwise you stall the pipeline.

Then again, the Alpha requires more instructions, so it's still somewhat
of a tradeoff.
