Re: looking for a PCI-X video card to borrow, errr.... PCI-E

[Dan Miller]

 This past week my system has been acting up. Before I go out a newer
 video card, I was wondering if anyone has a PCI-E that I could borrow
 for a week or so to either confirm or deny that what I'm seeing is a
 video card problem.

 I have a nvidia 8800GTX in there currently. If its the video card, I am
 looking at the same or newer.

Re: Dual boot (GRUB config for Linux and Windows)

[Michael ODonnell]

I'm composing this while down in GA dealing w/some family stuff
so I haven't been following the discussion too closely but I
wonder: Did you try that GRUB config file I provided?

It's derived from systems that I've worked with that are rigged
the same as the one you described and utilizes the "map" command
to fool Windows into thinking that the drive you told it to use
is the C: drive.  I suspect it's the droid you're looking for...

I presume you mean a PCI-_E_ (aka PCI Express) video card, not PCI-X.
That's something entirely different. Not that I have one I can spare
anyway, mind you.

I went to the BLU site hoping to find more.  At least a clue 
on the clock.  But a talk on rs232 comms...  (All of the 
hype and none of the clock?)  I hope it is a lot more 
interesting than that!

However, a direct connect to a WWV receiver technically can 
be a stratum-1 time server.

Is it one of the chip scale atomic clocks?  That would be neat.

OK, I jumped the gun :)  I guess I'm relly ahead of 
everyone on this!

That being said, are there any good primary sources that are 
affordable?  (Not WWV) Has there been any progress on chip 
atomic scale clocks?  A while back there was the NIST 
announcement ca 2005? on casc, but not much anymore.  IIRC 
it was only to consume < 100 mW and be the size of a sugar 
cube.

So instead of building an atomic clock, it's really an exercise in RS-232 or

Federico builds an atomic clock out of a pocket-sized 
Sheevaplug device



Any one go to this?  What was used as the clock?  How does
it get to be stratum-1?  That is reserved for a decent
clock, IIRC?  As in a primary reference, like caesium?

Technically, a Stratum-1 NTP clock means that it is 
traceable to a NIST reference by means other than NTP. The 
accuracy of the clock is stated in NTP messages. As a 
result, a Stratum-N clock could be more accurate in 
absolute terms than a Stratum-1 clock (although obviously 
not the one to which it is itself traceable).


For example, it's quite common for a Stratum-2 NTP peer to 
be within 25ms of absolute accuracy if it is referenced to 
a very good Stratum-1 NTP peer. If someone set up a lousy 
Stratum-1 NTP peer capable of only 100ms of absolute 
accuracy, this would be perfectly legal although fairly 
useless.

According to the announcement:

"Using the lowest amount of custom hardware and pouring Perl and Shell
Script over everything as the glue binding it all, we create a
minimalistic device delivering a perfectly tuned network time source:
your very own stratum-1 ntp server, turning a pocket-sized Sheevaplug
device into your personal atomic clock."

and http://en.wikipedia.org/wiki/NTP_server#Clock_strata

snipped for your convenience:

Stratum 0
   These are devices such as atomic (caesium, rubidium)
   clocks , GPS
   clocks  or other
   radio clocks .
   Stratum-0 devices are traditionally not attached to the
   network; instead they are locally connected to computers
   (e.g., via an RS-232
    connection using a
   Pulse per second
    signal).
Stratum 1
   These are computers attached to Stratum 0 devices.
   Normally they act as servers for timing requests from
   Stratum 2 servers via NTP. These computers are also
   referred to as time servers
   .

I would think this implies the Sheevaplug is connected to a Stratum-0 source.  
What was the
source that Federico used?  Anyone know?

OK, so GRUB says that your NTFS partition is (hd0,0) and that
your Linux partition is (hd1,0); so now that we've done a sanity-check,
I gather (never done it myself...) that you should be able to run through
this sequence of commands to boot Windows (NOTE: don't change the drive-
configuration--it'll cause the numbers the change):

rootnoverify (hd0,0)
makeactive
chainloader +1
boot

I'd try that on GRUB's command-shell, so that you can verify that each step
is working--if you can't run through the whole series and end up booting
the OS, at what point does something fail?

Now, I note that this `Windows on (hd0,0) and Linux on (hd1,0)'
is exactly the opposite of what you had in your first message, where you
wrote:

Initially, I had Windows as the first drive and tried to have the
choice using "boot.ini". I have since switched the drives[...]

Have you since switched them back? Is that how the Windows disk became #0?
Or is your computer doing something weird and, I don't know... randomising
them at boot?

And if the Windows disk is `the first one' (and I'm not entirely sure
what that means with SATA + your BIOS...), how is it that you're
booting into GRUB? Is GRUB installed into the boot-record on the Windows drive,
or do you have the BIOS set up to `boot from the second drive', or...?

What does it do/say when you try tab-completing on "root (hd0,"
and "root (hd1,"?

You can also actually run through a whole series of commands
(all the way to boot) from GRUB's command-line interface--
should be quicker than `edit the grub.conf and see if it works',
especially since you can verify things one command at a time.

That actually sounds like exactly the sort of thing I was talking about,
as having potential to mess-up GRUB's notion of which drives have
which number
