But, my MHL adapter didn't work.  It is also reproted here and here.

MX200 firmware update

A new firmware of MX200 SSD was released.

A system recovery image had been created, just in case.

Then, updated.

All existing data stored on SSD were preserved after updating.

Benchmarking by CrystalDiskMark version3 (MX200 500GB / mSATA3 / D54250WYKH).

The general performance seems to be inferior to the previous firmware?

Windows10 installed on Meegopad T01

Windows10 was released!!  I tried to install onto my Meegopad T01.

First, the upgrading from windows8.1 was performed.

About 2/3 of 32GB eMMC was used.

Display adapter and some devices were needed to be recognized manually as same as Windows 10TP.

Next, the clean instalation was done.  Windows10pro uses about 9GB of eMMC.

The volume label and the file index option couldn't be modified in windows10.  I wanted them but resulted in error.  However in Safe Mode, They can be modified.

SanDisk Extreme PRO USB 3.0 Flash Drive

Recently, I got SanDisk Extreme PRO USB 3.0 Flash Drive.

SanDisk Extreme PRO USB 3.0 Flash Drive (SDCZ88-128G)

and, SanDisk Extreme USB 3.0 Flash Drive (SDCZ80-064G)

Benchmarking by CrystalDiskMark on my NUC USB3.0 (SDCZ88-128G)

The result of SDCZ80-064G as control

This is nothing but large storage capacity ?

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.

mini PCI-express to SATA adapter (left)

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.

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.

Mavericks on iMac late 2006

In this time, Mavericks was installed on my iMac late2006 according to here.

Check the board-ID and compatible value.

For making an installation image, some files needed to be replaced or modified.  Because I made it from the bootable ISO image, some file permissions had to be changed by "sudo chflags -r nouchg [filename]".

Installing Mavericks.

Installation was failed on the final step but it did not matter.

Mavericks works fine on iMac late 2006.

In my case, a audio fix was needed.  I installed the latest VoodooHDA.pkg, executed Kext Utility.app, and rebooted.

Crucial MX200 SSD

I bought Crucial MX200 for my intel nuc D54250WYKH.

Installing on msata slot easily.

Then, I tried to clone my windows7 system from old SSD to new MX200 by using a system recovery on a windows installation disc from the system image in advance.  BUT, a windows installation disc was not able to recognize a USB3.0 HDD that stored my system image, even if USB3.0 driver was manually installed.  According to web infomations, USB2.0 storages are recommended for a system recovery, however, my NUC doesn't have USB2.0 ports but USB3.0 only.
I also used a windows8 installation disc which was said to support USB3.0 by default.  A system image recovering was started but stopped soon due to an error for mismatching windows version.
A system recovery couldn't also find my backup image although I connected the HDD which had been inside USB3.0 drive to SATA directly.  Finally, I created a backup image again on another USB2.0 HDD.  Nonetheless, the system recovery was still failed because of missing disk to restore in this time.  According to here, it was fixed by "clean" command on DISKPART.  Thus, my system cloning was completed and MX200 was resized.

Benchmarking by CrystalDiskMark (MX200 500GB / mSATA3 / D54250WYKH).

SSD upgrade of iMac late 2006

SSD upgrading was perfomed on My iMac late 2006 according to IFIXIT's guide.

I replaced HDD by mSATA SSD 32G with mSATA-SATA converter.

Moreover, internal cleaning was done.

Installing Mavericks.

Commemorative Coins for the 50th Anniversary of the Shinkansen

I got the commemorative coins for the 50th anniversary of the Shinkansen (新幹線, bullet train).

They are the five kinds of 100 JPY coins. The details in here (japanese).

Ubuntu MATE on INTEL-iMac late 2006

I tried to install Ubuntu-MATE 14.04 (ubuntu-mate-14.04.2-LTS-desktop-amd64+mac.iso) on my iMac late2006 (core2duo 2.16GHz), which had been retired recently.
Ubuntu was installed with pure EFI booting instead of Bootcamp because OSX was no longer used.  Unlike the case of PPC-Mac, the installation was easily done.

But, the long-time whiteout screen appears before booting when turn on the power.  According to here,  this boot delay occurs when installed by Mac-EFI mode.  Immediately, I tried to remove the boot delay by this instruction.

However, I couldn't run efibootmgr because "modprobe efivars" was never effected.

Next, I tried easyUEFI on bootable windowsPE, but the bootable disk created by easyUEFI didn't boot on my iMac. 

The Bootcamp mode (MBR) rather than EFI mode seems to be troubleless when using ubuntu on Intel-Mac.
