KNOPPIX 9.1 CD version

KNOPPIX is the very useful OS based on Debian linux, and can be run from live CD. However, recent versions of KNOPPIX became bigger more than 4GB needs DVD.  It can be installed on a USB flash media.

Easy2Boot is also very useful utility which can boot multiple OSs from ISO files stored in the single removal flash media.  But, recent KNOPPIXs were very difficult (not impossible) to be treated by E2B because KNOPPIX ISOs (>4GB) were not stored in the FAT32 drive of E2B.

In KNOPPIX 9.1, CD image is also released after several years !! It can become loaded by E2B.

KNOPPIX9.1 with E2B is the very powerful and portable tool for our computing life!!

HDMI to VGA Converter may become alternative of HDMI Display Emulator for headless PC

Most of stick PC including my Meegopad T-01 cannot be used without monitor (headless PC).  HDMI dummy plug (Display Emulator) must be necessary.

However,  HDMI to VGA Converter which is no use at present may become alternative of Display Emulator. I can access the monitor-less Meegopad T-01 by remote desktop with VGA converter.

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.

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.

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.

(This result of HTML5 benchmark test is NOT comparable with HDBENCH)

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).

Meegopad T01 can be supplied additional power via the data USB port

Meegopad T01 is very attractive.
From my experiences, at least 1.5A (5V) is necessary to boot OS (windows8.1).  OS doesn't start up on a low-ampere AC adapter.  However, T01 seems to be recieved power from another microUSB port (for DATA) additionally.  Then, dual low-ampere AC adapters can make T01 start windows8.1 at own risk.

Stabilizing Wi-Fi of ECS LIVA

My ECS LIVA is used as a Wifi router.
The wifi connections would be sometimes disconnected.  I checked the properties of Broadcom 802.11abgn wireless SDIO adpater but the settings of wireless mode such as g-only or channel-fixing were missing.
After some my trials, "BSS PLCP Header > long" on advanced tab improved my wifi conditions.

Meegopad T01 and windows10 TP

I bought a Meegopad T01 stick PC.
This stick PC is released without OS.  Correctly, non-activated windows8.1 is preinstalled.  Very manly, therefore very inexpensive.
Immediately, I tried to install windows10 TP claenly from DVD.  Some devices needed to be recognized manually with windows8.1 driver "光棍一号T01驱动.rar".
In my situation, the Wi-Fi conditions are unstable.  At present, it is hard for the daily use.

FON_FREE_EAP

The newly-updated FON firmware becomes to broadcast the SSID "FON_FREE_EAP", that is secured by WPA-enterprise protocole and unnecessary for the additional web-login.  This secured FON seems to be broadcasted from the fonera collaborated with SoftBank Japan (偽FON禿FON).  The official tutorial about FON_FREE_EAP is not disclosed as far as I know.
My setting in windows7.
 WPA-enterprise & AES
User authentication

In windows8.1, WPA-enterprise (not WPA2-enterprise) is missing from the internet connection settings.  Nevertheless, WPA-enterprise profiles can be imported using command line.  I exported this profile from windows7 machine, and imported to windows 8.1 machine (ECS LIVA).  It works fine.

Connectify PRO

I use my ECS LIVA as a wifi router.  NETSH commands and Ineternet Connection Sharing, featured by windows, creates a wireless hosted network very easily.  However,  the source to share the Internet connection must be configured manually, e.g. wifi, LAN, 3G or 4G modem.
I googled an automatic switching of ICS and the open source software SeventhGate was reported to have an option to select the suitable network connection as the source of ICS of  multiple connection sources, then I tried.


Unfortunately, SeventhGate doesn't work on windows8.1.
So. I googled again and found Connectify also had the same function but not in free version.  Moreover, now 70%off-offer was disclosed.   


I purchased and installed Connectify PRO and the automatic switching of ICS sources was established smoothly.

External antenna on ECS LIVA

I tried to attach external antennas to ECS LIVA for improving the Wifi sensitivity.


MHF4-RPSMA RF cables were purchased from AMAZON.


These uncool locations of antenna are due to the short-length of cable.  However, Wifi sensitivity becomes much better.
