To my knowledge, every new Intel CPU does have, available to a pin, the
collector-base junction of a parasitic substrate BJT. This device is
built-in the silicon die and can be used for precise measurements of the
silicon temperature - like in T (in kelvins) = (Vd(10*I) - Vd(1*I)) /
(k/q * ln(10))).
At least some Intel mobility modules do have a Maxim part that uses this
device and speaks out the temperature over SMBus.

Subject: Another SCSI-emulated IDE CD-R problem
Date: Sat, 15 Jul 2000 02:03:58 GMT
Well, I've read through several newsgroup discussions about CD-Writing
to SCSI-emulated IDE devices, but no one has reported the problem that
I'm having. When I try to mount any type of disc on my CD burner, it
fails with the following message:
# mount -t iso9660 /dev/scd0 /cdr
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems
It's lying. It dosen't actually mount the device -- or it does, and
then immediately fails. Below is the output from syslog when attempting
the mount, as well as the rest of my environment. I can, however,
successfully mount any disc on the DVD drive, which is also
SCSI-emulated on /dev/scd1.

Subject: hd partition/cylinder alignment errors
Date: Sat, 15 Jul 2000 02:32:42 GMT
greetings all:
i have a small problem i am hoping someone can help with...
i made the mistake of thinking that i could install redhat 6.2
from a local cdrom smoothly onto a second hard drive on my system,
while maintaining the orginal hard drive system.
i had system with 1 drive and cdrom working very nicely.
then i installed a brand new hard drive on the secondary ide which
showed up nicely as /dev/hdc
sometime early during the install process, the partitions on my
/dev/hda got all messed up. or at least that is how linux sees
them.
here is the output from '/sbin/fdisk -l /dev/hdc' ...
Disk /dev/hdc: 128 heads, 63 sectors, 847 cylinders
Units = cylinders of 8064 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hdc1 * 1 5 20128+ 83 Linux

/dev/hdc6 72 137 266080+ 83 Linux
/dev/hdc7 138 203 266080+ 82 Linux swap
[root@nneale /mnt]#
on bootup i also see this:
...
hdc: FUJITSU MPA3035AT, 3337MB w/0kB Cache, CHS=6781/16/63, DMA
...
this appears correct.
Partition check:
hda: hda1 hda2 hda3 hda4 < hda5 hda6 hda7 hda8 hda9 hda10 hda11 hda12 >
hdc: [PTBL] [847/128/63] hdc1 hdc2 < hdc5 hdc6 hdc7 >
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 40k freed
...
the [PTBL] tag is something i have not seen before...
the system types and sizes according to fdisk appear to be
erroneous. going from memory, here is what they *should* be:
/dev/hdc1 500 mb winnt
/dev/hdc2 100 mb /
/dev/hdc3 96 mb swap
/dev/hdc4 extended
/dev/hdc5 300 mb /usr
/dev/hdc6 100 mb /tmp
/dev/hdc7 100 mb /opt
/dev/hdc8 rest /home
interestingly enough, despite what fdisk reports, i can do a:
'mount -t msdos /dev/hdc1 <mnt_point>' and view the contents of
what should be the win nt partition. it looks intact, but i
have not tried booting nt from it. i can not boot linux from
from it as i get a kernel panic.
i tried to mount the linux partitions, but no dice.
i could probably remember the sizes and types of what they are
*supposed to be*, but i don't know of any way to 'back out' of
the partition realignment.
does anyone know of any neat tricks to recreate the partitions
without losing any data?? i would like to get some ideas before
i start tinkering. if i don't learn anything to this effect in
3 or 4 days, i'll probably just trash it and start again.
i don't have any critical information on the drive, but i would
like to bring it back rather than start all over again. i am
not optimistic that i can save anything, but i would like to try.
i would be grateful to any ideas which might assist me in bringing
these partitions back from the apparent vortex to which they have
slipped.
thanks much.

Date: Sat, 15 Jul 2000 03:06:19 GMT
Trying to run XFree86 4.0.1 with the .094 drivers from nVidia on
a Riva128. X runs fine (runs great actually), but every time I
try to run an OpenGL app, I get the following message as soon
as glXChooseVisual gets called:
NV: could not open device /dev/nvidia0
...followed by an app-specific message about not being able to
find an acceptable visual. I tried this with my own apps and
with a couple of GLUT apps. If I wipe everything out an start
with a clean install of X, everything works great. Works fine
on the Mesa-Glide drivers too, and on 3.3.6 with the nVidia
drivers. I checked the FAQs, made sure I completely erased
Mesa before I installed the nVidia drivers. I also tried the
.092 and .093 drivers, same result.
Since I can't find any mention of this problem on the net, I'm
thinking it might just be me. Has anyone else seen this and
found a work around?
Thanks,
Jason

Move the patches to /usr/src and from that directory,
./linux/scripts/patch-kernel. Make sure you use an "original" kernel,
not one that has undergone other patches (like RedHat's, for instance).

Yes, I tried mounting an *official* RedHat 6.1 cd, a CD-R that I burned
on another drive, an Oracle for Linux CD, etc., etc. Nothing works.
And the CD's I mentioned above mount just fine on my DVD drive...

And how about the region-coding issue? I understand that the
first-generation DVD-ROM drives allowed playing titles from any region,
whereas DVD-ROM drives in current production have the region remembered in
the hardware, and it can only be changed a handful of times.
Are any first-gen. DVD-ROMs still available? eBay only? Do they work with
Linux better, worse, or the same as current-production DVD-ROMs?

Howdy. My company has been trying to move to redundant hardware solutions
where possible, to reduce potential outages.
We have a couple of rack-mount NT servers that have built-in hot-swap RAID
arrays, redundant power supplies, and redundant network cards with automatic
failover.
I told my boss that I thought several companies sold boxes like the one
described above, but with Linux pre-installed. However, I'm now having
trouble finding any. Did I lie, or are they out there?
We'd be trying to keep the cost down as much as possible. (I suppose we
could do the Linux installation ourselves, if there was a particular server
with the above properties on which Linux was known to work completely.)

Sorry, my apologies, I was thinking of "NLX" motherboards when I
posted. I believe this is what will be required to fit in a 1U

To view mpegs at the console in Linux (and hear them), go to freshmeat.net
look up smpeg. On smpeg's page they will have the source (maybe binaries)
and also a link to SDL which you will need.
You will need SVGA and have to tell SDL to support it (by default, it won't).

Look at your dmesg output which will tell you what device is associated with
the tape. In this example, /dev/ht0 and /dev/nht0. A link /dev/tape ->
/dev/nst0 is common practice.
Most people remove ATAPI tape support and add SCSI emulation and SCSI tape
in their kernels even if there are not true scsi devices. I have run both
ways, throughput is the same, scsi emulation seems to be less prone to
positioning and [bogus] error codes.

'mt -f /dev/nht0' most likely. Also 'man mt'

Look under /usr/doc first, particularly the HOWTO section.

What it did under W9x is irrelevant for devices and most everything else.
Unlike the W9x world, most drivers in linux handle many different devices
within a family, so the case of a 'special' device driver for Brand X is not
usually a thought.
