I think you be yanking my chain. I don't recall ever posting a

I remember some christmas family pictures.

Yep, but I was the photographer. "The Old Prospector" is likely my
father ;-)

In the unlikely event that you DO have a photo of ME, I would be
wearing suspenders.... I dislike belts ;-)

Well, I didn't save the attached pictures. The christmas tree was on
the right hand side of the picture. I vagely remember a person wearing
suspenders, not wearing a jacket, not wearing a tie, and somewhat turned
to the right, holding a glass. Not bold, reasonable amount of white hair.
Perhaps your wife took the picture.

Then there is a chance you might have been captured in a reflection in
one of the ornaments in the tree.

No, they are garters. Back in the early 1900s, before elasticated

This pertains more to win98 but may provide some help.

There are 16 IRQs (15 usable) in a computer system. Here is a typical
assignment of these IRQs:

IRQ 0 System- System Timer
IRQ 1 System- Keyboard
IRQ 2 System- Cascadeable PIC (programmable interrupt controller), controls
IRQ 8-15
IRQ 3 System- Serial Port (COM 2 and COM4)
IRQ 4 System - Serial Port (COM 1 and COM3)
IRQ 5 Available- General Adapter Use
IRQ 6 System- Diskette Controller
IRQ 7 System- Printer 1
IRQ 8 System- CMOS Real-time clock
IRQ 9 Available- General Adapter Use
IRQ 10 Available- General Adapter Use
IRQ 11 Available- General Adapter Use
IRQ 12 System- Mouse Port
IRQ 13 System- Math Co-processor (even though this is built into the CPU, it
still uses an IRQ)
IRQ 14 System- Hard Disk Controller
IRQ 15 Available- General Adapter Use

As you can see, there are five (5) IRQs that are not assigned by the system
design. Of these, one usually goes to the graphics card, one to the USB
ports, and one to the modem. That leaves two (2) available IRQs for
everything else. With care (and use of the proper cards), this is normally
sufficient.

Loading Sequence for Additional cards:

First:
Internal Modem (PCI)
Second:
Sound Card (PCI or ISA)
Third:
Network Card, a.k.a. NIC (PCI or ISA)
Fourth:
DVD Devices requiring Dxr3 Decoder Board (PCI)
Note: Some video decoder boards require two (2) IRQs for complete
functionality. Check with your video decoder card manufacturer for video
decoder support and requirements.
Fifth:
SCSI Adapter (PCI) (This assumes that the system does not have a SCSI hard
drive.)
Sixth:
Any others.

I am looking at my system in both system information, and in the computer
properties.

I cannot see the following IRQ's: 3, 5, 7, 11, and 17. I am very
curious to know why Windows did not assign them, and doubled up others to
be
shared?

The second thing is that I cannot seem to figure out what USB device is on
what USB Universal Host Controller. Each controller has a set of ports in
association with it. I found the Host Controller addresses.

What I want to do in the end, is to determine exactly which USB device is
in
which port when viewing it in the System Hardware Properties.

It turns out that one of the USB Host Controllers is being shared in IRQ
with the ATA hard drive. Another Host Controller is being shared with a
modem. There is another one that is being shared with the video display.

I have an HP 4670 Scanner, and it is giving loss of communications
problems
because of the IRQ sharing. I found this out after doing a lot of
searching.
To get around that, I used the USB Host Controller that in shared with the
least demand. This was the one that is shared with the modem. The scanner
was now, only failing to communicate once in a while.

To resolve the issue, I added an active USB hub to act as a type of
buffer.
It actually is slowing down the USB communications. With this approach,
the
scanner seems to be working for now. I tried it many times over the coarse
of the evening, and it has not failed yet.

What I am looking for, is if someone would have an explanation for this???

Save a REG file with these keys. I have one that I restore every time I

Yeah. Time was that the repub leadership had to plot to keep Newt G
from visiting the White House, because he was falling under Bill's
spell. He is some sort of supernatural force.

Charisma without principles is dangerous. Rhetoric, looks, music, and
emotion can sway feelings in most any direction. I think JFK and
television began the US craze for electing people just because they
look and sound cool; Viet Nam was our reward.

I recently saw a talk by Dick Morris. He said that Bill and Hillary
have one overriding thing that binds them together: Hillary's great
love for Bill, and Bill's great love for Bill.

Cleaning out a closet recently I stumbled across a Radio Shack kit I built
when I was just teaching myself electronics (2/25/80 according to piece of
tape I stuck on the side of the box). It's a "frequency standard" -- a
one-transistor oscillator with a 100 KHz crystal and a variable capacitor
for trimming the output. Unfortunately I can't find the instruction sheet
that came with the kit. As built, there are two wires (one each Red &
Black) that come out connected to a power switch. I'm sure that the curcuit
isn't very complex (total of 5 R, 4 fixed C, one Q, one Xtal and one
variable C) and while I could trace it out, I'm not really that interested
in the analysis of it as much as I am in seeing if it still works. But,
without the instruction sheet, I don't know what voltage to apply. Yes, I
could drag out a variable power supply and run it up slowly, but I was
hoping that someone might either still have the instruction sheet handy or
know what voltage it requires. (I tried a single AA cell and got no
oscillation; I can imagine that it was designed for 5V or 9V or anything
inbetween).

The old Radio Shack kits were designed for 6V and 9V. Crystal
oscillators usually involve enough series resistors that it doesn't
matter much.

Thanks. I'm in the process of checking out that site, but at first

not intend to control my cooler with a computer; some of the products at

that has it's own memory/program, and therefore operates completely
independently of external computers.

You could also take an LM34 temp probe (temp -> voltage) and a
comparitor along with a potentiometer to split the voltate to
feed the comparitor.

When the temp reaches say, 22C, the LM34 will be putting out 2.2V.
(perhaps the LM35 is centigrade, I forget). If you're set point
is 2.2V, the compatir goes high, drives a relay and turns on your
fans and lowed the dry ice into the warm water. (ok, whatever you need
to turn on).

Thanks. Unfortunately, I'm not as knowledgeable about electronics as
I'd like to be, and I'm sure that the above is probably pretty
fundamental, but it is still over my head. This is just fidgeting with
some hobby equipment, and I can do very small scale stuff -- like wiring
a simple thermostat to a fan and small transformer. I thought and hoped
that this could be something about as simple.

I'm looking for a programmable digit thermostat ... possible to program a
thermostat to constantly drop the temp at a controlled rate (e.g.,
4-5F/day, max)

snip

Anyone know of any product that can do that? If need be, I can manage
manual adjustment of the thermostat each day, although I'd prefer to not
have to do that because sometimes I just won't be available.

And Chuck, thank you very much for your response. If something simpler
doesn't come along, maybe I'll be able to figure out something with it.

I'll get right to the point, and then add more info below for those who
want to read further. I don't know if this sort of a device exists, and
I've just spent all afternoon googling -- trying to find one -- without
any success at all. I hope that some kind person here will be able to
point me in the right direction. Thanks in advance for any help.

I have been a homebrewer for 19 years now and I use a Penn temperature
controller with remote bulb. You can't always go by what the tempereature
says on the control ((it may say 35 degrees, but it will be 39 inside, so
you have to play with it), but it keeps the temperature consistant for
lagering (the one I have has a differential setting on it). The cap tube on
the bulb is about 6 feet long, but I just leave the excess curled up inside
the fridge. It doesn't have to be a Penn brand. There are quite a few other
brands that will do the same thing. Check with your local homebrew shop or
ask someone you know that is in the HVAC business (and can get you one at a
supply house).

Do a Google search on "Homebrew Temperature Control" and you'll find oodles.

No picture, but here is one for $52:
