This motherboard, case, and power supply are the core of my desktop machine and
the machines I build for clients. The 2.4C processor and 256 MB of RAM
represent skimping to get the price down to near $400.00. Honestly, if you're
going to build a new hyperthreading box for yourself, spend the money to do it
right. You're a developer and power user; time is money. $600 vs. $400 now
will save you countless hours over the next several years.
I have a Pentium 4 2.8E GHz processor; current is 3.0E. I recommend it for
power users and SOHO servers (+$32.00):

I have and recommend 1 GB of matched pair DDR 400 for 800 MHz FSB Pentium 4
systems (+$94.00):

Here's the hard drive I use in all systems ($59.79):

Here's the script running on my machine:
dpchrist@p42800e:~/mydocuments/cygwin-issues/hyperthreading$ cat test
#! /bin/ksh
mypath=$(pwd)
while [[ ! -z $mypath ]]
do
mypath=$(pwd)
if [[ -z $mypath ]]
then
echo "Test Failed......Path is empty"
fi
done
When I fire it up in two Cygwin Bash windows, one or the other fails within 3 to
10 seconds:
Trial #1:
dpchrist@p42800e:~/mydocuments/cygwin-issues/hyperthreading$ ./test
Test Failed......Path is empty
Trial #2:
<CVSENV>dpchrist@p42800e:~/mydocuments/cygwin-issues/hyperthreading$ time ./test
4 [exiting thread] pdksh 3684 cygthread::stub: erroneous thread activation
(shell locked)
Trial #3:
dpchrist@p42800e:~/mydocuments/cygwin-issues/hyperthreading$ time ./test
4 [exiting thread] pdksh 2532 cygthread::stub: erroneous thread activation
(shell locked)
Trial #4:
