Windows7 running on Powermac G5 (experimental) - part4

Recently, Lubuntu powerpc becomes stable and QEMU also becomes more stable and compatible.
I found the report of windows7 running on qemu / macport of OSX but it was reported to be still slow compared with VirtualPC for Mac 7.02
Then, I tried to run windows7 on QEMU2.0 / Lubuntu 14.04,1.

First, install qemu
           apt-get install qemu
    for sound emulation
           apt-get install pulseaudio

Second, I converted the previous disk image file installed windows7 starter (VPC for Mac 7) to qcow2 file.

           qemu-img convert -f vpc -O qcow2 diskimage.vhd diskimage.qcow2

QEMU for PPC-linux can simulate at most 2047 MB RAM while VPC7 can do max. 512MB.  QEMU can also be simulated multi-processor or -core, however windows7 starter supports only uniprocessor.
For sound emulation, "-soundhw ac97" option is needed and the driver must be installed manually (link).

          qemu-system-i386 -m 2047 -smp 2,cores=2,sockets=1,threads=1 -localtime -vga std -soundhw ac97 -hda diskimage.qcow2


Unfortunately, Windows7 on QEMU/Linux was slow as same as on VPC7 with ramdisk.
Sounds also work ....but with severe delay.

On my several trials, a little speed-up could be observed when a disk image file was on high-speed USB drive (I used SANDISK EXTREME) than on the internal SATA HDD.
Other faster devices (SSD or RAM disk) may show better perfomance.  I hope for the future updates, for expamle more RAM could be assign.

Garigarikun WIN !!

Garigarikun (ガリガリ君) is the most popular ice pop in Japan.  It is very inexpensive but delicious with a lottery.  I won at the first time while I had eaten over 50 ones in this summer !!  It is said that the winning rate is 1/32 (3%).


This stick can be bartered for another ice pop.

PowerPC Lubuntu kernel

When the new updates including kernel 3.13.0-35-powerpc-smp were installed, the bug appeared again.  I felt the kernel 3.13.0-33 and 3.13.0-34 were very stable.  So, the kernel was changed to 3.13.0-34 and it's working good.

SIM-unlocked softbank 007z part 3

Even if sim-unlocked and firm-updated, the connections to NTT Docomo of my softbank 007z are not stable.  According to 2ch, a softbank 007z supports Band9 (1.7GHz) and Band11 (1.5GHz) only, Band1 (2.1GHz) is not supported.  It also imformed that the modified 007z for BIZ firmware makes it possible to catch Band1 in exchange for unsupporting Bnad9 and Bnad11.
Change "SBMFAREN_JP_MF80" to "SBM_JP_MF80V1.0." by Binary editor and flash.
The connection to NTT Dococmo becomes very stable.  However, this is not recommended, as it is said that the restoration to original firmware is impossible.

Planex GW-US54SAG on windows7 64bit

Planex GW-US54SAG is not officially supported to windows7 and also 64bit vista.  To use on windows7 64bit, I tried some other drivers.




Then, I installed that driver and choosed the model as Allied telesyn AT-WCU201g Wireless USB Adapter.  Now, It works fine.  But this driver seems not to support the softAP mode.

Eating loaches

Traditionally, loach is the stamina food of the summer as same as eel in Japan.  This is a pot dish of loaches at the Shibuya branch of Komagata Dozeu (駒形どぜう).  It matches a cold beer well.

Lubuntu 14.04 for PowerPC becomes stable ?

The first point release of ubuntu 14.04.1 was disclosed.  In original release of lubuntu 14.04, there were some troubles around Geforce 6600LE videocard on my PowerMac G5 (late 2005).  Especially, the bug of mouse cursor with noise often appeared and caused the kernel panic.

Although the yaboot parameter "video=ofonly nouveau.noaccel=1" was used, I didn't feel a remarkable change.  However, this bug seems to disappear after recent updates !?
