SATA and USB3.0 upgrade on PowerMac G5

The late 2005 models of PowerMac G5 have PCI-express slots while a few PCIe boards for powerpc-Mac were sold out.  But, on linux, the radeon HD videocard for WIN-PC was reported to be work fine (link, link).  I tried to install Transcend PDC3 (USB3.0 / SATA III combo card for WIN-PC), which I used on my WIN-PC.  This PDC3 is compatible to PCI-express 2.0 1x but PowerMac G5 has only PCIe 1.0.

The Samsung 840EVO SSD was connected to PDC3.

Lubuntu 14.04 recognized my SSD without trouble, then I run a benchmark test by  "hdparm" command.

On the benchmark test, the SSD proved twice as fast as the one connected to internal SATA I slot.  However, that speed is almost as same as SATA II because of PCIe 1.0 of PowerMac G5.  SSD connected to PDC3 is of course unable to be used for a boot drive. 

Next, USB3.0 was tested.  From my experience, newer kernels of ubuntu cannot recognize USB3.0 while the older kernels (e.g. 3.13.0-36) are good.  Moreover, SATA and USB3.0 don't seem to work together at the same time on PDC3.  

I used SANDISK extreme USB for a benchmark test, that was connected to PDC3 and internal USB, respectively.

On the benchmark test, the USB3.0 proved ten times as fast as the internal USB2.0 although it wasn't match for the full speed of USB3.0.
If using PCIe x4 cards, more better paerfomances may be seen.

Ramen Senryu

My favorite ramen senryu (仙龍).  This is "Horumon ramen", which is of soy sauce with much backfat, long onion, and pig's intestines.  Chinese chili is best much to this ramen.

SSD (samsung 840EVO) on PowerMac G5

As far as I know, Samsung 840EVO is one of the compatible SSD for PowerMac G5 whereas only some models of SSD can work with PowerMac G5.  I bought and installed it for my PowerMac G5 (late2005 model).  The 840EVO, whose firmware was updated on WIN-PC, is very fast and quiet while PowerMac G5 has only SATA I.

I tried to run a benchmark but the standerd benchmark test of PPC-lubuntu couldn't work disappointingly. 

Then, the hdparm command was used for a quasi-benchmarking.

Expectedly, the speed of 840EVO on PowerMac G5 was only as SATA I.  However, I am satisfied with the present tweaking.

ISW13HT HTC J on FOMA plus area

HTC J (ISW13HT), japanese custom model of HTC valente, is my favorite smartphone.  It has been developped to get ROOT, S-off, and SIM unlock (link in japanese).  Recently, I'm using HTC J with Docomo MVNO data-only SIM (iijmio).  In previous android versions,  the problem of "cell standby" battery drainnig would occur in a data-only SIM according to here.
However, the improved fix of HTC J was already disclosed in here (japanese).

In addition, the special modification for HTC J to catch FOMA plus area (W-CDMA 800MHz band XIX) was also disclosed in here.  I adapted these mods to my HTC J with some difficulties.

Yesterday, I traveled to Hokkaido on business.  Then , I comfirmed the above mentioned mods worked well (connection was established on FOMA plus area and antenna pict was displayed).

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.
