New USB3.0 driver of D54250WYKH

I'm using Intel NUC D54250WYKH.  Recently, I found some new drivers were released on web site.
Today, I tried to install them in my machine.

At the time of USB3.0 driver (Version: 3.0.5.69), I uninstalled the old driver first and then installed the new one.  But, the SETUP showed a driver install error "This computer does not meet the minimum requirements.."

Why?  I tried to install this driver repeatedly or manually at the device maneger.  However, every usb devices became unrecognized completely because of my mistakes.  Neither USB keyboad nor USB mouse work in Windows, Oh my GOD!!
There is the warning message about this trouble on the Intel web.

USB mouse and keyboard were recovered by "Last Known Good Configuration (advanced)" option at the boot menu.

So, I gave up the new driver regretfully and installed the old driver again.  However, the same error message appeared in the old driver.  Why?? I had installed it previously and it worked well until just a while ago.
I considered and then remembered about BIOS update.

Downgrading BIOS from 0040 to 0035 was done.  And the new USB3.0 driver was re-tried.

Now, the installation was completed!!

The BIOS version 0040 may have bugs?

Belated CPU upgrade of DELL Inspiron 531s

I got a Athlon 64 X2 6000+ at the very low price of bargain corner.

I upgraded CPU in my DELL inspiron 5351s that Athlon 64 X2 5600+ was originally equipped.

It was very easy to assemble this machine.

Only 0.1 point up on the processor subscore.

This CPU upgrading improved performance a little dispite its power consumption (65W of Athlon X2 5600+ / 89W of Athlon X2 6000+).

Trim Enabler cannot support miniPCI-e SSD with SATA2 adapter ?

KingSpec KSM-SMP.5-064MJ is a mini PCI-express type SSD (not mSATA) for some EeePC models.

Trim is also supported.

I tried to install KSM-SMP.5-064MJ into my imac with SATA2 adapter.  

I bought it via Amazon which brand or model number was unknown.

mSATA to SATA adaper (right)

Trim Enabler said "The patch is active but Trim is not working...." even if several rebootings were done.

On windows machine, Trim is supported through miniPCIe-SATA adapter.

And its speed was presented.

A issue of restoring Windows7 system image

I experienced the trouble when restoring Windows7 system image from external USB HDD.  At first, I hypothesized that USB3.0 drivers didn't work well.  However, from my some investgations, Windows7 system image recovery program might lose recovery images if multiple images (or different versions) were stored in "WindowsImageBackup"  folder of the same HDD.  I had stored Windows8.1 (x64, UEFI) image in that folder as well as Windows7 system image (x64, MBR).  After I moved my Windows8.1 system image to another folder, Windows7 recovery program could recgnize my system image properly.

Benchmark test of Windows7 on QEMU / PowerPC linux

At the request, benchmark tests were performed on QEMU-Windows7 on my PowerMac G5.
However, recent releases of PPC-ubuntu were so buggy that most of benchmarking tests became frozen before finishing.

At first, XBENCH score of my PowerMac G5 (2.0G Dualcore, late2005, GeForce6600LE) was shown.

Next, the rarely finished result of HDBENCH (japanese) among numerous trials.  The settings were as follow;
           qemu-system-i386 -m 2047 -smp 2,cores=2,sockets=1,threads=1 -localtime -vga std -hda diskimage.qcow2

This is the result of EEEPC 4G-X (celeronM 630MHz, Memory 2GB, GPU Intel 910GML / Intel GMA900), as contorl.

Needless to say, the Windows7 virtual machine by QEMU-PPC linux is very slow.

Softbank 007z and C01HW don't have GSM mode ?

Recently, I traveled on business to Philadelphia, USA.  I brought my sim-unlocked 007z and C01HW, wifi mobile routers.  My 007z was flashed by 007z for BIZ firmware.  C01HW is a sim-free model originally outside Japan.  As far as I know, it was not obvious whether 007z and C01HW were usable in GSM area or not.  I tried them with T-mobile SIM.

T-mobile USA is using 3G of 1700/2100MHz (AWS), which is of course not supported by 007z nor C01HW.
Softbank 007z and C01HW recognized T-mobile sim but displayed "No Service".  I check every settings on the web-based utillities but they never connected T-mobile USA.  Therefore, it is supposed that 007z and C01HW don't support GSM mode as well as AWS.

My ISW13HT could connect T-Mobile USA at most EDGE speed.
