Sharp ROMs / Cacko ROM Over/Underclocking suggestion...
« on: May 13, 2004, 01:16:12 pm »
I have a suggestion for the overclocking applet. It should have an \"Auto\" option where it automatically runs in one set mode eg. \"Normal\" when running on battery power and another set mode when on mains power eg. \"Default PXA255\".

This is speaking from the C760/860 POV

You **** my wife? (British joke)

Yeah uhh, who finds polls annoying and stuff. I sure do when they are being used so much as of late

Sharp ROMs / Changing the startup logo
« on: April 30, 2004, 02:17:28 am »
Well this is a tricky thing to do and I can\'t get it to work.

I removed the symlink in /home/QtPalmtop/pics144/Startup_screen.bmp.bz2 and made it point to /home/zaurus/Documents/Image_Files/Startup_screen.bmp.bz2 which is my custom made bootlogo but it doesn\'t seem to change.

I created a 640x480 full colour image and then rotated it 90\' to the right before bzipping it up but when I reboot I still see the Cacko loading image.

Anyone know what I\'m doing wrong here?

I wish to state that these are unconfirmed but they are suspicious.

While looking for a serial lead on expansys I noticed that they had the SL-C700 available for pre-order ( and this filled me with curiousity and doubt.

During my lunchbreak today I phoned up Expansys to check the status of my serial lead and to inquire about the C700 being sold. Here is the dialogue:

(Me: Foxdie, EL: Expansys lady)
Me: I notice that you\'ve got a newer clamshell model zaurus down as preorder on your site. Are you importing them or getting them from Sharp UK?
EL: As far as I can tell we\'re not importing them. We have a system where we put brackets around the product name and/or state in the product description if it\'s an import. This product has no such label
Me: So who will deal with the warranties?
EL: Expansys ourselves usually deal with product warranties.
Me: What about service and support?
EL: That would come from Sharp
Me: Sharp UK?
EL: Yes
Me: Thanks

At this point I phoned up Sharp Electronics UK to confirm this:
(Me: Foxdie, SUKL: Sharp UK Lady, SUKPM: Sharp UK Product Manager)
Me: Hello there, I hear that Sharp UK are soon to be distributing the clamshell zaurus models in the UK. Is this true?
SUKL: I don\'t think so. Sharp UK are not really supporting the Zaurus line anymore. I could be wrong however. I could put you through to a product manager if you wish.
Me: Yes please
SUKPM: Hello?
Me: Ahh yes, hello. I am trying to find out some information on the Zaurus line, in particular the clamshell model. Expansys has this product marked down as preorder and they have told me that it\'s not an import and that Sharp UK deal with the service. Is this true?
SUKPM: As far as I know this is not true. Sharp UK have stated that they are dropping the Zaurus line in the UK and will continue to offer service and support only for the SL-5 series.
Me: What about imported Zauruses?
SUKPM: Those have to go back to Sharp Japan for service.
Me: Okay thanks, goodbye

To me this all seems iffy. Why would Expansys import C700\'s and fail to specify it\'s an import? This would mean that Expansys is openly liable for all warranty return costs to Japan and back again (which is about £140 return trip in fedex delivery costs alone).

I am not one to start rumours but my thoughts are that perhaps Sharp UK are attemping a silent rollout of the clamshell model in the UK to gauge how popular the product will be.

From what I\'m told on #Zaurus on which is one of the main Zaurus IRC channels, Raduga tells me that Expansys USA also has the SL-C700 down as pre-order.

I\'ll let you make up your own minds. Please feel free to comment and debate.

I wish I could post my resumé here but it\'s got too much sensitive information in that I don\'t want to give out directly.

I\'m looking for an IT support (assistant) role between the Birmingham City area and Redditch, Worcestershire.

General Discussion / Zaurus WAS Bricked, Now solved!
« on: March 29, 2004, 10:10:38 am »
Edit: This used to be a post called \"Zaurus Bricked, suggestions?\" but as I\'ve now recovered it which is documented on Page 3 I don\'t think it needs any more attention other than from those of you who have near-bricked your C series Zaurus and although you have the option to do a NAND Flash Restore it fails with the error \"Format Error\". Good luck with your restores people and take better care of your Zaurii, I sure will

Well for the last month my C760 has been out of action, it was killed by a combination of my own stupidity and a bug which has since been resolved with the Cacko ROM and Bluemonkey Bluetooth CF cards.

Here\'s a retrace of my steps:

The bug above meant that I couldn\'t power on my Z, I could get into the service menu but not the ROM flashing screen (where you hold down OK as you turn the unit on). I thought at the time that perhaps there was a problem with the NAND Flash, so I performed a NAND FLASH Read test. Naturally I assumed that because this said READ and had no mention of Writing that this wouldn\'t affect the Zaurus. The menu option I chose is outlined in this path:

Main Service menu ] Page 3/3 ] Option 7 EXTRA MENU ] Option 1 Zaurus Test ] Page 2/4 ] Option 8 NAND Flash Read

I did that and it was so far back that I can\'t remember the result of it, but it definately didn\'t mention anything about erasing / deleting / changing anything. Then I tried Clear Diag Flag Option 6 in the EXTRA MENU and then Reset Option 9 in the same menu.

Now, at this point I didn\'t think I had done anything wrong. I will openly admit this was probably an arrogant / retarded view on my part and boy oh boy do I feel like a complete f***ing idiot now!

The Zaurus reset and then the Mail LED was flashing green. I felt sick at this point.

In the past I\'ve experienced this after tinkering with the other service menu options. I should have been smarter than this but we all have our days where intelligence dissapears but luckily a NAND Flash Restore borrowing a friends 256MB CF card has fixed my Zaurus...

I talked to sashz to see if he could help out and he pointed me to a page with some wierd files to put on a CF card. I learnt today from reading\'s forums that this is a low level recovery solution for those that can\'t even get into the service menu but I tried it anyway. I couldn\'t get this to work, it didn\'t do anything (and I have no way of monitoring the serial port) so I gave up for a while as I was thoroughly annoyed with it.

About a week ago offroadgeek was very kind in giving me my own 256MB CF card, that arrived today so I downloaded the SYSTC760.DBK file to do another NAND Flash Restore from. As soon as I got the card I formatted it as FAT16 and put the file on it and tried reflashing. The error I get is this:

I can access the service menu fine and post numerous screenshots of any screen there if it would help, here\'s the bottom part of the main service menu screen, I\'m hoping it shows something that can help initially:

[img]\" border=\"0\" class=\"linked-image\" /]

Right now I\'m at a loss, I\'ve searched both this and externe\'s forums for help and I\'ve tried what they\'ve suggested and I don\'t know what to do. Please tell me there\'s someone out there that can help me!

PS. I\'m not sure if my Zaurus has a warranty, it was definately bought in the last 12 months but I don\'t know if it has a warranty, I bought it from a guy called Lawrence Camera on eBay, all I remember about him is he\'s a good friend of the person who runs I doubt he\'ll replace it because of what I\'ve done to it  :?

As the topic says, w00t

May the ZUG keep being prosperous.

General Discussion / Posting Etiquette
« on: March 16, 2004, 03:05:58 am »
Okay people listen up. We used to allow guest posting in any part of the ZUG forums, but the few spoilt it for the many by attempting to start flame wars.

We understand however that people simply don\'t wish to register, so we have created a segregated section of the ZUG forum for guests to post in.

Here are the ground rules:
1. No Swearing
2. No Flaming
3. THINK before you click that \"Submit\" button if there is anything in your post that may cause offense to others. If there is, don\'t bother posting.
4. You may reference other posts from the non-guest posting forums but don\'t expect a decent reply. It may be that people ignore this part of the forum because they don\'t want to interact with guests.
5. All IP\'s WILL BE LOGGED. If you disagree with this, don\'t post!

Rules 1 to 3 apply to those who register too. We expect that people should remain professional in their posting. It may be conditional that you might get away with mild flames such as \"In the past, such and such ROM has failed on me\" but posts like \"This ROM sucks, it keeps freezing my Zaurus, learn to code {insert name of ROM creator here}!\" will be deleted.

If posts are deemed worse (swearing, blatant posting to flame) by any of the ZUG team then in all likelyhood you WILL have your IP (and if needs be multiple IP\'s and half octets {eg. 291.51.*.*} banned from posting).

If you don\'t agree to what I have outlined in this announcement then don\'t bother posting. If you want to post in the other forums you MUST register. Registration is free and any email addresses submitted will NOT be signed up to mailshots or other spam and kept in the strictest of confidence.


Cxx0 Hardware / Overclocking / Underclocking...
« on: March 06, 2004, 02:02:07 pm »
Okay I am creating this thread to alleviate the heated discussions of overclocking the Cxx0 series of Zaurus from other area\'s of the Zaurus User Group.

This is how I have come to understand things as an overclocker of various computer equipment. For the last 3 years I have owned a AMD Athlon 1GHz PC which has been overclocked to 1.3GHz with no problems. The CPU stays under 45\'C / 115\'F (a CPU is considered to be overheating at 65\'C / 150\'F or above) no matter how hard it gets pushed, on these grounds I consider myself quite knowledgible about overclocking devices.

When you overclock something you have to take 3 factors into consideration. Stock (original) CPU speed, what cooling the CPU has and how much the CPU is going to be used at any given time.

The Zaurus doesn\'t have much in the way of cooling, however because the XSCALE CPU is designed for low voltage and it doesn\'t have a FPU it also means that it\'s not going to generate as much heat. Overclocking can void your warranty (but only if you tell the retailer you overclocked it ) and can damage your CPU IF you push it too far.

Within the latest Cacko ROM you have 5 fixed overclocking options which are safe to use on any Cxx0 Zaurus, provided you follow the guidelines later in this post. First of all I would like to take you all through what CPU clock speeds the overclocking utility permits you to set.

[img]\" border=\"0\" class=\"linked-image\" /]

As you can see, when you overclock or underclock the Zaurus you are also changing the values of the RAM (not the storage media) and the bus speeds (the speed at which the CPU communicates with other devices). No matter what value you choose there should be no corruption of data (although if this has happened please correct me, I haven\'t heard a report of it yet!).

People who should consider overclocking:
    People who run emulators eg. gnuboy

  • People who want to use their Zaurus for Video
  • People who need to calculate data faster, for example WEP cracking
  • People who think the Zaurus is running too slow

    People who don\'t need to overclock:
      People who use PIM\'s eg. Calendar App

    • People who use their Zaurus for MP3\'s
    • People who surf the net and/or use WiFi
    • People who use communications Apps like QPE-GAIM

      People who should consider underclocking:
        People who use e-book readers

      • People who are checking email automatically
      • People who generally want to display the same screen / image without it changing
      • People who want to get more battery life out of their Zaurus

        Overclocking with the tray applet in the latest Cacko Qtopia ROM is safe. It doesn\'t push the CPU speed too far and there is a minimal heat increase. If you\'re still a little wary of overclocking but feel it may help you here is a guide based on model:

        C700: You can run it at the Overclock level but only for short periods of time (no more than 15 minutes), it pushes the memory clock quite high in relation to it\'s stock speed. The default for the C700 is \"Default (PXA250)\".

        C750, C760 and C860: You can run it at the Overclocked level for as long as you desire but don\'t use it for more than an hour if you wish to keep your Zaurus in top condition. The default for this series is \"Default (PXA255)\".

        Remember, when you\'re charging your Zaurus battery, extra heat is generated, due to this you should cut the above overclock time in half if you have your Zaurus connected to it\'s charger.

        Cool down time for all Zaurus is 30 minutes. After 30 minutes has gone you can safely overclock again. Be warned though that repeated overclocking / underclocking can cause heat expansion which can physically damage your Zaurus.

        Other ROM\'s have the ability to set the clock speeds differently, you can set the CPU as high as you want with it. As such this is very dangerous. You should NEVER overclock your Zaurus more than to 471 MHz (the next step up is 530 MHz which is too far). Use the table above as a guideline for the maximum safe overclocking speeds!

        Please feel free to ask any questions, and also before you post PLEASE use your common sense when typing your posts. Any post that is deemed by myself or the other ZUG team as inappropriate or in any way offensive it will be deleted.

        Okay this is well warped, I\'m slowly surfing the normal forums and watching a friend play the new balders gate game and suddenly all the posts are marked as read.. This happened at about 6PM UK time 14th Feb 2004 (time given for reference)

        Software / SR: Autoroute-style Road Nav App
        « on: February 10, 2004, 03:13:30 am »
        I actually posted something similar as a reply to another thread but that doesn\'t appear to be going anywhere.

        I am looking for some software for the Zaurus (preferably for the 640x480 C series, but I can live with 5x00 versions) that\'ll give me directions from A to B on the UK highways (or US with UK maps). Something similar to Microsoft\'s Autoroute 200x would be fantastic.

        There was some basic vector style software that I saw (zRoadmap rings a bell but i\'m unsure) but a). that had no UK maps, and . it\'s visible appearance was equivelant to looking at someone knitting.

        Although it\'s not a requirement, GPS features would be good too. I\'d love something like the system currently available for the Ipaq called TomTom ( but I\'m not picky.
