[maslovsky]

You guys are way too fast

I don\'t know how that happened but somehow an intermidiate ROM build got out.  Sorry for that. The latest ROM is available here:

http://www.zaurususergroup.com/modules.php...q=getit&lid=193

Helvetica Italic Fonts have been removed form ROM and repackaged:

http://www.zaurususergroup.com/modules.php...q=getit&lid=194

HostAp wireles drivers are available here:

The new ROM entry should appear in the ZUG Downloads area soon. For now use direct links.

Below is the contents of the readme file. Have fun.

PS: Dont worry about words \"at least\" in ragards to partition size. Exactly 26 Mb is enough

Info about installation and FAQ look on our site: http://www.cacko.biz
IMPORTANT:  This ROM requries a flash partition at least 26 MBytes in size!
    Make sure to repartition your internal flash before updating ROM!    
Installation:

    1. Extract the 3 files - initrd.bin tools.tar updater.sh - to the root of your CF or SD/MMC card.
    2. Make sure that Zaurus isn\'t plugged into AC power.
    3. Remove battery for at least 5 seconds.
    4. Replace battery (replace battery cover, lock cover), plug in AC power.
    5. Press and hold the \"OK\" button on the keyboard.
    6. Turn the power on, you should see the Japanese service menu.
    7. Now Plug in the Power Cord. (You will get an error if it isn\'t plugged in!)
    8. Select option 4 (flash/update).
    9. You then have four options (1. USB, 2. CF, 3. SD, 4. Back)
    10. Choose either option 2 or 3, depending on which media you put the files on.
   
    11. Select \"5 Flash repartition\", enter at least 26 when prompted for root partition size.
    12. Flash will be repartioned and Zaurus will reboot.
   
    13. Repeate steps 2-10 again and wait for the menu start menu.
    13. Now select \"1 Install new ROM\" and wait - Zaurus will reboot.

Moving to new thread as requested since this the the \"right\" version  
Is it possible to backup the previous Cacko QT ROM, flash the new one (after repartitioning to 26 meg) and then recover from the prior backup?

TIA,
 Mike

Is it possible to backup the previous Cacko QT ROM, flash the new one (after repartitioning to 26 meg) and then recover from the prior backup?

No, I would not recommend doing that. Tthe ROM structure has changed from previous versions. Sorry, but you\'ll have to reinstall your applications.

However, you can save your settings but manualy backing up /home/zaurus/Settings folder and then restoring it. This is safe.

Also, you can back up your PIM data by saving /home/zaurus/Applications/dtm folder and restoring it on the new ROM.

This is for the C7xx/8xx series only?  Looks very interesting.

[CoreyC]

I\'ve installed it and think it is great.

1 bug I have found:  My clock in the panel somehow changed into Japanese numbers.  I am not sure why it happened, or even when, but I am sure it was english when I first installed the rom.

Rebooting fixed the panel clock, but this could be an annoying problem if it happens too often.

Great work team Cacko, thanks

[zuraus]

will this work on an american sl-5600?

thanks, and good work!

[offroadgeek]

this isn\'t an actual problem... probably just a quirk with me... but the icon for the overclocking is so cool (in my mind) that I want to use and play with it.  It reminds me of my old Saab with a turbo charged engine... it was great to actually feel the turbo kick in...

oh well... I don\'t dare overclock my precious 760...

[tamarian]

Flashed it using 26 megs. and all is working great!

I\'ll repeat my post on the intermediate build:

The new ROM looks great. I used 30 megs, no problems. And it\'s a lot faster. GPRS CF installed fine. This is the first time I tried Opera, since it was always slow compared to Netfront. But Opera 7 is looking good.

Well done Cacko team! You are the best!

Now, who is Daniela?

[maslovsky]

This is for the C7xx/8xx series only?

Yes, it\'s only for C7x0/8x0.

Now, who is Daniela?

Actualy, I  don\'t know. But I bet sash does

oh well... I don\'t dare overclock my precious 760...

Actualy, it\'s pretty safe to overclock PXA255 processor.

[anonuk]

sorry maslovsky, yesterdays rom was what sash uploaded to my webserver, i just passed on the files and links.  Ill change the link on myserver to the new urls so noone will download the old one by mistake.

Sorry guys, I offered my server to sash for distribution (a few people were anxious to try the rom), woke up the next day and found he had uploaded those files so i posted. Sorry if it did anything bad to anyones machines :-(

I guess i\'ll stay out of the way of releases next time.... i was just trying to help.

[maslovsky]

sorry maslovsky, yesterdays rom was what sash uploaded to my webserver, i just passed on the files and links. Good work on the kernel!

Actualy it was me who uploaded the files, but they were ment for sash, for testing.
Anyway, I think now we have cleared things out

I am still getting the strange \"ghost\" effect on my screen with this rom, but it looks like I am the only one.  does anyone have any idea why my c760 is so special?

Actualy, it\'s pretty safe to overclock PXA255 processor.

Careful with that comment...see the following:

http://www.inboost.com/pc-boost/cpu-booster.html

http://news.com.com/2009-1040_3-253289.html

and this link that makes specific reference to a PDA that runs XScale: http://www.viewsonic.com/products/pocket_p...pocketpcv35.htm

Where it says the following in the warranty about the XScale processor:

1-year limited warranty on parts and labor.  Overclocking Warning - Intel® processors are validated and supported only when they are operated at their factory rated settings. Operating a processor faster than it was designed (overclocking) can cause permanent damage to the processor, and possibly other system components including the motherboard. Other negative results are possible including the inability to boot or calculation errors. Operating a processor outside of specification will likely shorten the life of the processor, and can also void any available product warranty.  Overclocked processors can product unpredictable results or system instabilities, which might not be readily apparent. The life of the processor may also be shortened. The expected frequency is the frequency at which ViewSonic warrants the reliable performance of the processor. Damages caused by overclocking are not covered under warranty.

Try to do a \"echo 75 ] /proc/driver/w100/fastsysclk\" from console as root.
Let me know if it helps.

[maslovsky]

2 Guest: So what?  Yes we know that overclocking shortens processor life - it work only for say 10 years instead of 15. Actualy even Intel itself overclocks its processors - how else do you name selling the same processor with a different multiplier? Pentium 4 2.4 and Pentium 4 3.0 have abs0olutely no difference other than multiplier. But look at their prices...

I\'ve been overclocking elaost everything all my life - from Pentium 75 to my GeForce4 Ti...

It\'s always up to you - overclock or not...
