If the cache size shows up as zero, you probably have a defective chip.
The BogoMips rating is a bogus estimate of how many million
instructions per second the chip can execute. (One reason why it's
bogus is that it uses "multipliers" to fudge with the number.)
A Pentium-III 500MHz gets 496.44 BogoMips and 497.85MHz, according to
/proc/cpuinfo. That's about in line with your result.

Check out Intel's developer Web page documentation on "Specification
Updates." But in short, whenever Intel makes a significant change to
one of their chips, it receives a different stepping code.

Subject: Newbie: USB modem support?
I just installed Mandrake 7.1 and it seems my modem is not recognized.
I'm using a hardware corrected Boca Tidalwave (USB external). I was
told that if I compiled a newer kernel that my modem might then work.
Anybody know for sure? I also have NO IDEA how to compile a kernel. I
don't mind doing it if it will solve my problem, otherwise it doesn't
seem worth it.
Email replies welcome.

To clarify: The "actual" BogoMips rating for your CPU is going to be
much higher. The value Linux reports is only a fraction of the
total. There's some stuff about this in a HOWTO, I think.
For example, a P2 and P3 might have the same rating, because P3s have
a greater divisor. (Not a "multiplier" at all, but a divisor. There
I go.)

Is this about the udma/66 cable length true? At the local computer
stores they sell udma cables in 18/24/36 lengths. I've got 18's on my
promise100 redhat7/2.2.17 box here and I'm having all sorts of
problems. I don't know that anything shorter then 18's would even
work in my full-tower case....

I'm seeing similar behavior, but my Promise ATA100 isn't built into
the motherboard, it's a PCI card.
My system is a redhat7,2.2.17 w/ ide patches. The kernel is built
similarly to the above.
The pc was running fine with one drive off the promise channel1, with
a normal ide cable.
I bought another drive, a Maxtor 80gb, and two udma/66 18" cables -
one cable for the new drive, one to replace the original normal ide
cable.
And I'm seeing flakyness galore. Mostly ext2fs errors when the new,
2nd drive (on the promise 2nd channel as master) has 500mb or more
data written to it.
If I unmount that 2nd drive, and run e2fsck on it, it'll lock the
machine.
Upon rebooting, in init1 mode, e2fsck'ing the drives off the promise,
will lock the machine.
The *only* thing that seems to stop the errors and lockups it to
a) remove the 2nd, new drive
b) remove the 2nd new drive and switch the first drive to the plain
old ide cable.
The machine is still fsck'ing the rest of the drives. After I get them
all cleaned up (or if) I'm going to play some cable swap games with
the udma/66 cables and plain ide cable on the first/second hard drive
and see if if the card and drives do not give me problems when there
are no udma/66 cables involved.
I'm posting this, and emailing both of you because the thread in
comp.os.linux.hardware is from a week ago. Sorry if it annoys you.
Please reply or post back if you have any thoughts.
Thanks,
Shane

Hi,
I have a problem installing RH7.0 using FTP. The network card is
Dlink-DFE503-TX. I saw many posted news about the driver: via-rhine.c.
Apparently, it can be loaded AFTER installing the RH7.0. My case is want to

did not like the network card.
Anyone have succeeded in this case ?? IF so then how.
Thank you.

I'm pretty sure that 4 Front have recently introduced support for that
Ripoff -- oops, I mean RipTide -- soundcard in their OSS drivers. The
"modem" is now sold by Conexant but is, nonetheless, a Rockwell chipset
HCF modem and, thus, is best replaced by a real modem.

This is a common problem with Linux and the PIII. The cache *should* be
there; the kernel just isn't reporting it. If you think there is no
cache in your chip, you should get memtest86 (freshmeat.net) and try
that out. It has an option to turn the processor cache on and off; you
should notice a slowdown when the cache is off.
BogoMIPS are bogus. They have nothing to do with how fast your CPU is.
They're just used for some timing loops in the kernel. My K6-2 400
posts 799.54 BogoMIPS, and a PIII-600 will be faster even though the
BogoMIPS value is lower. Check the BogoMIPS-HOWTO at
http://linuxdoc.org/HOWTO/mini/ for the full story.
Processors come in "steppings" generally. After a chip is released onto
the market, engineers continue to test it and/or solicit bug reports
from OEMs and users. If engineers find bugs in the chip itself, they
can update the microcode in the chip, and they release these new chips
as stepping 2, 3, 4.... Having a stepping 1 chip should not present a
huge problem for you. HTH,

Hmmm. I don't know for sure, but the readcd utility that comes with the
cdrecord package might help.
readcd dev=0,0,0 f=filename.raw sectors=0-30000
might do something, or it might not. The CD-R you burned is most likely
not recoverable, but the data you put onto it might be recoverable with
a deal of time and effort. Unfortunately, there is no fsck for the
iso9660 filesystem.
You might try "cdrecord --toc" to find out the sector range of the first
session, use "readcd sectors=0-SESSIONEND" to get the entire first
session, then use "readcd sectors=SESSIONEND-300000" to try and get the
data from the second session. This may not work, but at least it's
something to try. Please post the results you get; I'm curious to see if
this will actually work. HTH, good luck....

The following should work in all cases:
setserial /dev/ttyS2 port <modem base IO port> auto_irq autoconfig
(the base IO port is from /proc/pci). Any serial device (ttyS*) can be used,
e.g., ttyS4 or ttyS25; it is completely irrelevant what "com port" Windows is
using.

Ok, this is weird. When I boot the machine, my memory test goes up to

machine with. However, I've just recently noticed that top, asmem and
other memory-load checkers are reporting only 64Meg. What's going on?
Am I missing something obvious? I thought my machine was spending lots
of time grinding on the hard disks, and it appears that X is taking up
86% of my memory leaving only about 12Meg or so for all my apps -- no
wonder I'm swapping so much!
Anybody know why only half my memory is reporting? If I'd blow a SIMM or

You have to download the driver, compile it, move it to you modules directory,
run depmod -a then load it using modprobe. Then it works fine.
Yea, I found it very annoying that they didn't provide better support. Heck
they didn't even host
the driver on their website, but it is a very good 10/100 card for under $15...
