I would be really interested in 128MB memory upgrade.
Since I have C3100 there isnt enough space inside for bluetooth, is there?

Hardware Mods / New 8gb Microdrive
« on: April 06, 2006, 08:37:41 pm »

Was thinking about doing the same upgrade to my C3100....

Have you noticed any difference in battery usage or performance???

Was it difficult to swapout drives??

How did you prep the new 8GB MD?

I did just couple hours ago. Performance seems to be about the same but i didnt perform any tests. The power specs for the drive are about the same as Hitachi MD so I wouldnt worry about battery either.

As for the preparation. I already had my original HDD repartitioned (128MB swap on partition 2 and the rest for ext2 on partition 1) so I did the same on new HDD, mkswap, mke2fs, mount and then
cd /mnt/ide
cp -a bin etc home usr tmp and whatever /mnt/cf
and thats it

Replacing the drive involves

- shutdown -h now
- unplug power
- remove the battery, cf and sd cards, stylus
- unscrew 6 screws on the back (one is covered by stylus!)
- remove the back cover
- be careful with battery compartment lock, it can fall of the back cover so place it back where it belongs
- unscrew 4 screws with -> arrows from the mobo
- remove sync port cover
- remove motherboard, be careful here there are two flex connectors going to keyboard and display, either disconnect them or manipulate the board with them and top half of zaurus attached
- on the other side of the board unscrew 2 screws and remove sd card reader
- remove plastic bracket that holds the microdrive (2 clips on each side of the board)
- remove old microdrive
- insert new microdrive (add foam pads like on original drive or something for shock protection, i used 5 layers or isolation tape, be careful not to cover the vent on the back of the drive)

- and now do everything in reverse order ;-)

thats it

I just upgraded my C3100 to 8GB Seagate microdrive from Amazon. It works like charm. Seagate announced 12GB microdrives recently but I think only for embedded applications - only with TrueIDE mode.

I got burned once when I bought 8GB Memorex microdrive USB drive and tried to use the drive in Zaurus - it is crippled 8GB Seagate, TrueIDE only.

I dont like the idea of full HDD install on 3100! Its a waste of 128mb and bad use af the HDD!!! ()spin up/down all the time)
128MB is nothing compared to 4GB HDD so it is not much waste. All the file modifications, log files, installing, symlinking and whatnot burns out flash and eventually will break it. It is much more mess compared to just having rootfs on HDD. Spinning up and more power usage is not much of a problem. I already have swapfile and most applications installed to HDD so it will not make any difference really.

I had thought you could install the rootfs package to the hd and chroot..or something like.  I haven't tried it.

I would like to see a different partitioning scheme, though. /home /var and /tmp really ought to be on the hd, or at least the option should exist.  Maybe do something lile a /boot and a pim data or something on the flash? A ton o the read only system stuff?  I'm Not at all sure how that would would be done, and clealry I haven't thought too much about it, but the idea is interesting.

This will only complicate everything even more. I really like the clean approach in OZ on C3x00, too bad the OZ package collection sucks.

It would be cool if there was option when installing pdaXrom to select whether to use flash or HDD for rootfs.

I have tried gqmpeg player. It is fairly simple and it seems it should be possible to create a 640x450 pixels size skin for it - button and slider sizes are definable. It even has integrated skin editor which is totally weird in use though. I tried to design my own skin but gave up for now.

xmms is not so simple to look at, but I find it works well once you trim it back to the one window only and learn a few keyboard shortcuts to play/pause/next etc.

Yeah, try adjusting volume with your finger.

Zaurus - pdaXrom / Hdd Based Pdaxrom For C3100?

I can see that pdaXrom for C3000 uses the HDD for rootfs. New OZ for C3x00 series also is HDD based. I really dont like the idea of /var/log on flash file system or /tmp being in precious memory. I think it would be great if pdaXrom always installed to HDD on C3x00 series.

Is it possible to instal C3000 pdaXrom on C3100 without changes?

I know there are many.
But what I really need is something simple, with full screen uncluttered interface so I could use fingers to control the playback and volume.

Is there anything in the feeds? Or is there a player that would fit the description so I could compile it?

Zaurus - pdaXrom / Charge_percentage
« on: March 29, 2006, 06:03:19 pm »
What happened to /proc/driver/battery/charge_percentage ???

I was using it in some of my scripts.

Can I bring it back?

If not, what should be used instead?
On my C3100 /proc/apm holds the battery percentage charge.

-- cheers
[div align=\"right\"][a href=\"index.php?act=findpost&pid=120863\"][{POST_SNAPBACK}][/a][/div]

Yeah, except on mine it shows 255% charge.

Zaurus - pdaXrom / Authoritative Ports Collection?
« on: March 24, 2006, 04:49:07 am »
pdaXrom uses gcc 3.4.5-xscale-softvfp compiler. So I guess it must be softfloat.
(does it mean that float math is done by compiler libs? in that case how is hardfloat handled? real fp opcodes in code emulated by kernel?)

also, here is ufraw version that uses libexif (and libexif itself)
or you can try libexif from gphoto thread

Zaurus - pdaXrom / Ufraw 0.7, Htop 0.6, Gtk-engines-thinice
« on: March 24, 2006, 02:37:58 am »
Hi guys.

I managed to compile couple more things.
gtk-engines-thinice - My favourite GTK2 theme. Small widgets good for 640x480 screen. (Actually I use it on my 1920x1200 desktop as well)

htop - sexy process viewer/manager, replacement for top

lcms - little color management system


ufraw 0.7 (uses lcms). ufraw is raw conversion utility for images from digital cameras. I had to modify the main dialog layout to almost fit into 640x480 screen. It loads and converts images from my Pentax dSLR just fine. It takes A LONG TIME to convert the image, like couple minutes. This should be useful for previewing images on trips or so. Take SD card from the camera, put in Zaurus and play!


Zaurus - pdaXrom / Running povray probs

You guys are crazy. Z doesnt have floating point on a CPU. Povray is going to be as "fast" as on an Amiga
