Da Blitz,
If I remove the 7 screws on the bottom of my Kohjinsha, will the bottom come off without disturbing any of the inside components?
The reason I'm asking is I want to replace the 40GB hard drive with a higher capacity one.
I wonder if that would void the warranty.
Thanks,
Doug
I know this isn't addressed to me but....
If you are absolutely sure that you really want to do this, I could give you some pointers as I have taken both my K's apart. I would not recommend it as the connectors holding the flex cables are very fragile. I am assuming that my warranty is void.

well i found a list of winbond wifi cards (its like pulling teath) and i would agree that its the W89C35D 11g USB2.0 Card as its the only wifi card they make that uses usb
there is one funny bug with it, i can see it but cannot enable or disable it with the hotkeys like with bluetooth, so i am assuming that its power pins are not connected to the usb port but instead to the internal power rails, not that it matters
there is a 2.4 dirver by winbond themselves, i did manage to find a product brief that lists the features (such as aes and all that stuff and Wake on WLAN). so unless there is someone with time to burn i would not expect there to be any wifi support as this chip is RARE, and i do mean rare. i cant find any mention of other hardware with the chip, and there is no direct link to the docs on the winbond website.

Ok, Linux purists, look away now

It turns out another option for Linux on the Kohjinsha is to use VirtualBox to run a Linux virtual machine on Windows. The speed is surprisingly good (even in GNOME) and the virtual network operates through the built-in WiFi perfectly. With the VirtualBox guest OS drivers installed I can even run fullscreen at the native 800x480 resolution. This post is coming to you from Firefox in Ubuntu 6.06LTS on my SA1! That is a pleasant surprise considering neither VMWare nor Parallels will run on this machine.
The downside is that it takes a relatively long time to boot, and I'm sure that it's still not as fast as running native. Lastly, if you want direct access to hardware for things like WiFi hacking, this isn't going to cut it. But if you just want to run Linux apps in a real Linux environment (as opposed to something like Cygwin), this is not a bad solution.

Good news indeed, and thanks for the tip about the little-known VirtualBox !

If you google for "kohjinsha", it will list www.kohjinsha.com.
It is a Japanese website, but google will translate it (sort of).
Anyway, scroll down the page for a link to drivers.
There are linux drivers for the following:
> Media slot Driver - Improvement of compatibility of SDHC card
> AES driver - For kernel 2.6.x
> Chip set Driver - For kernel 2.6.x
> Video driver - For kernel 2.6.x
> Sound driver - For kernel 2.6.x
> Mouse driver - For kernel 2.6.x
> Wireless LAN Driver - For kernel 2.6.x
> Bluetooth Driver - For kernel 2.6.x

Impressive catch -- we're so accustomed to having to reverse-engineer everything that the last place we'd look is on the vendor website (especially in Japanese :-)...
The Google tools are surprisingly good for this, too.
Da Blitz, is this for real ? Unfortunately it seems the Wifi file contains binary, not code...

now i am impressed with them (and i thought thier windows setup was good)
actually the only thing we really need from them is perhaps the video driver and definattly the wifi, everything else is in the mainline

Apr 22 2007, 06:32 PM
well a quick load of the module and i get an error saying its not in the corect format
thanks for playing try againg next time

anyway it disagrees on symbol struct_module, i am assuming its because i am running somthing latter than what the module expects
if they have a binary perhaps they have more. will get an email message formatted and ready to go. if there is anyone who speaks japanese who wonts to proof read it and make sure its easy to translate then feel free to post

Apr 23 2007, 01:43 AM
Could you elaborate on that, fpp?
(EDIT: Full specs (courtesy of conics.net)
HERE. Costs about 902$, whilst the non-touchscreen models cost about $769.)
Anyways, what's the general consensus on this one? Is it good, or more importantly, is it worth the money?
I'm pretty sure that it has enough horsepower to handle general tasks (office & internet), but what about multimedia? How's the 3D performance (I'm not talking about anything recent, but more like Quake 1 or something like that.)?
It seems like a good device, but I've seen similar devices that are much more powerful (though more expensive, quite obviously) from Fujitsu, and some UMPCs, that are quite similar (but keyboardless).

While I'm semi-tempted by the new touchscreen Kohjinsha...
But then started thinking that by the time that you get it with 1GB RAM and 100GB HD, you've now spent about the same ($1000 +/-) as what a new or refurbed Fujitsu P1610 is going for on eBay...
Granted the P1610 is slightly larger (about 1/2" wider and 1/4" deeper...) but, it has better specs and probably better build quality, right??
Of course, then I start thinking about the new Fujitsu 'McCaslin' mini-TabletPC that Intel just showed as part of their presentation.....
So, it goes....

that annoyed me when i heard the anounment, but thats what i get
anyway it plays quake 2 at native rez just fine without slowdown, you might even be able to shoe horn quake 3 on there with the graphigs turned down (i had everything enabled for quake 2, but with a hacked autoconf file)
youtube plays fine if you turn the quality to low, sits at 90% when playing
Da_Blitz
Apr 24 2007, 04:28 AM
the windows tests are simple, basically i didnt leave windows on there for long and never played with the monitor
what i need to know is if you want a higher rez on the monitor output does that also put that same rez on the screen (ie if you wanted 1280x1024, is that the same rez bieng pumped out by the monitor and the lcd screen)
i assume thats the case and that you cant change them independentlly, i might point out that under linux at the moment i have the lcd at 800x600 and the VGA out downscaling the 800x600 lcd output to 640x480 (it looks bad but its ok for some things)
i am assuming at this point in time that the "video for linux" part that isnt mainline yet controls the scaling eigine. email msgs from AMD indicate that they were not concontrating on this feature or would leave it till last so its inclusion on the kohjinsha website leads me to belive that it is controlled thrugh that interface rather than presenting a second monitor output (which it cant do and would be ugly in x.org as the second one couldnt display anything)
one advantage is that the rez could be changed easily (output, not the display) althogh xrandr handels that well these days

Dir Sirs
We are a group of mobile computing enthusiast who use or mainly run linux on our devices such as the zaurus by sharp.
we noticed on your website patches for the 2.6 linux kernel for driver support of the hardware on the device. however we noticed that you provide a binary driver for the widcomm wifi chipset.
We have tried loading the module however there was not enough infomation provided to tell us which kernel it is compatibel with. after looking around online we could not find the source code to this device so that we could use the device. having the source code would be the ideal solution as we would not have to worry about the diffrent kernel virsions and which ones are compatible
we humbely ask you for accsess to the source code so that we may use wifi under linux
thank you for listining and taking our requests into consideration

i tried to approach them in the manner i believe the are accustomed to, i am not sure if i hit the nail on the head with that one but i feel i was close, anyone good with the culture with emphasis on business deals? i think thats the aproch to take but my experince only comes from watching one to many anime (for refrence i hae gone for fudeal japan in the way i talk to them. ie talking to someone who is of higher class)
tell me if i am crazy. thats just what i think and i like to pretend i understand psychology... and spelling
i dont want to force the GPL postion in the opening rounds, i dont think that is a good way to aproch it and i am not sure about the leaglease stuff in this case, you know how the wifi companies are. i belive in this case if they felt "threatened" by the GPL they would mearly pull the drivers. i will make an offsite backup before posting of the drivers in case they pull them and we latter need the drivers

Yes, it's in French, but it's not about a KJS, he's grappling with a USB Wifi adapter with a Winbond chip. Maybe it's exactly the same as in the KJS though, so if the NDIS wrapper gimmick works for him it might work for us...

as a side note, been having problems with S3 suspend, the other day i noticed it turns on at random. i did some thinking while in bed and as soon as i thought of it the thing turned on by itself
i didnt know there was a telepathy module in there, i will have to check lsusb again

anyway, seems you cant disable "turn on from S3 when lid is opened" which i find anoying as a slight twist of the screen can turn the thing on without anyone noticing (supprising how long that battery lasts when playing mp3s/doing nothing, it defitattly gets 5 hours and i think i can push it to 6 hours)
final note is that acpitool -B gives you how much battery capacity the thing has in its battery pack (in miliwattts) as well as its current consumption in mW's
lcd off, and playing mp3s/ doing nothing it draws 420mW, screen on 550mW, battery capacity on mine is 2550mW fully charged (it tells me its rated at 2540mW but charged to higher

I am mostly running windows on mine and almost never power down. I just put it on standby and am quite sure that at least a couple of times it randomly turned itself back on. I have noticed some bios upgrades on the Kohjinsha site. On another note, I would hate to see this discussion leave. I know this is an oe site and all that but this information is useful in an overall sense even though it is not specific to the Z. I think we should ask to have a 'Mobility Linux' section added to this site or the tyrannozaurus site.

Has anyone tried using external CF wifi cards that they use with their Zauri?
I am asking because apparently the built-in usb wifi is not working well under Linux and as I found out it is most likely not supported in wifi wardriving software like NetStumbler or AiroPeek/AirMagnet.
I am considering purchasing the touch screen model on my trip to Singapore in the end of the month , but having wardriving capabilities is important to me and if internal card is not supported then at least being able to do it with my Ambicom card that serves me so well with my Z.

May 4 2007, 10:42 AM
The Kohjinsha has a Type I CF card slot
see specs.
A wireless CF card is too wide (Type II) and will not fit in the slot.
Actually, the slot is wide enough, but they have put in some bumpers that prevent you from inserting anything wider than a regular CF card.
I don't know if a wireless card would work in it if those bumpers were removed, but I'm sure doing that would void the warranty.
Someone should check it out (but not me)
kopsis
May 4 2007, 03:10 PM
Actually, most CF WiFi cards I've used are Type 1. The only Type 2 CF "card" I've seen is my 4G microdrive. I don't have any of my WiFi cards handy (the beauty of the SA1 is that I don't have to carry all that junk around any more) but I did find an old wired ethernet CF card and when I plugged it in, Windows detected it and prompted me to install drivers. I didn't try to go any farther than that (since I know this particular card is broken), but I don't see any reason why it shouldn't work.
Now, whether Linux running on the SA1 would see it may be another matter, but I believe a few posts back that someone (Da Blitz?) determined that the CF slot was being handled as PCMCIA just like it is on the Zaurus.
