OK, Now the Real New Cacko Qtopia ROM

[Anonymous]

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?

Frank

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

yes, this worked!  so what does it do?

- Added option to boot into a \"true\" Linux console at runlevel 2:

When \"Wait...\" message appears during boot, click \"/,\" button and select \"C\".
You can switch between tty1-tty6 using Alt + Arrow keys or typing chvt [1..6]
To return to Qtopia, type \"init 5\" as root

Interesting...
I\'m thinking this might make easier to load another ROM on SD; or am I getting way too ahead of my newbie self?  :wink:  At this point, wouldn\'t it be great to be able to dual boot from Qt to pdaXrom and back with out reflashing & reinstalling everything?

There were several a threads in devnet on this topic, sigh...

Anyway, great work sashz & company! This is the best Qt ROM so far, love the qkonsole & kernel with wireless & monitoring mode.  maslovsky, nice work on the kernel. It definately seems to run faster (with default clock).

Cheers,
Jerry

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...

You said \"Actualy, it\'s pretty safe to overclock PXA255 processor.\" which really is not a correct statement.  This is a far cry from saying \"It\'s always up to you - overclock or not...\".  I simply disagreed with your comment that it is safe based on hard data as shown in the posts.  Others have found that thier Z gets warm when overclocked.  Perhaps for someone like you, its not a problem to \"burn out\" a Z as you can just go buy another one.  However for many users on this site, they scrape together coins and work hard to afford a CXXX.  So to release software that has the potential to damage a user\'s hard earned Z, its probably much more responsible to say \"It\'s always up to you - overclock or not...\" rather than \"Actualy, it\'s pretty safe to overclock PXA255 processor.\"  Remember, if someone\'s Z has a melt down (which you have no idea whether it will or not - and guaging by its warm temperature and lack of ventilation, I would assume you are more wrong that right on this point), are you going to come back and say you never said it was \"Ok\" to overclock?  Just trying to be responsible here, thats all

Lets not argue here guys.

Overclocking carries a small risk, agreed.

The default install of this rom *DOES NOT* overclock your cpu, it only gives you the ability to do it.  You also have to use a utility(provided in the rom) to do this, so it can\'t be done by accident.

A 10% or 15% increase, especially on a temporary basis will very rarely destroy anything, only where the part is of a lower sytandard in the first place.

Don\'t forget you can also *underclock* the cpu too, save battery power and prolong the life of you chip, great for ebook reading.

Guest, you have pointed out the dangers, thank you for that. This rom simply makes that choice available to more people.

Manufacturers use these disclaimers to stop people doubling their cpu speed without extra cooling, and then taking a molten bit of plastic back and asking for a refund.

Peter,

I agree on all points.  I had concern that the author was stating it was \"safe\" to overclock, and I think it was irresponsible to state that, thats all I was trying to point out.  Keep in mind, there are lots of n00bs on this site and when a person of authority makes a claim like this, I think its not appropriate.  I\'m just trying to help out

[zbones]

good, I am glad we are all freinds  

I  really apreciate the work that the cacko team has put into this rom.  I would not have a c760 now if it wasn\'t for this board, and the constant supply of new sorftware/roms to play with.

I wil use the overclock facility, but only for apps that really require it, not all the time.

It is good to point out potential dangers to people who may not know better, but please do this constructively. There is nothing worse for a developer than to have his latest release torn to bit\'s and labeled dangerous when the risks are very low, especially when the feature is turned off by default.

To the Cacko team, another excellent rom. keep up the good work but maybe a disclaimer pointing out some of the risks to using the new features may be a worthwile addition to the readme.

Installing any software, especially a new rom, can be risky, but imagine the risks the developer has taken in order to produce this rom/software for our benefit, and he\'s not even charging for it either.

Well, hold on now.  This is where we disagree.  Nobody tore his bits and labeled any of his code as dangerous.  I labeled his incorrect assumption of calling overclocking \"safe\" as dangerous.  His statement and assumption were completely incorrect and I backed it up with data.  I fail to see where it was not done constructively.  I simply pointed out that he should watch his comments as they were not responsible.  It is understood that his code releases are welcomed by the community.  However, calling over clocking \"safe\" was plainly wrong.  Had he originally stated that he has used over-clocking  and has not personally encountered any problems and that there may be risks involved with over-clocking, then there never would have been an issue.  But calling it \"safe\"?  That was out of line.

I have two comments:

1) i think the 3rd link (the hostap drivers) is bad on the download at the start of this thread. maybe it should be http://www.zaurususergroup.com/modules.php...q=getit&lid=195?

2) I was going to comment on the overclocking thing, but I think that topic should die where it is.
this is a lot less typing anyways

Thanks for the call out.  I changed the links to the ZUG Downloads entries to help track downloads and obviously muffed it up  

It\'s fixed now.

I agree with your second point... enough said.

I flashed my C860 with the new ROM and it great except for one thing.  The C860 is no longer recognized as a disk drive device when you connect it to your PC using the USB cable.  Is there a way to fix this in the setup screens?

[maslovsky]

2 Guest: You stil did not convince me (and could not). It is my personal opinion that it is safe  to overclock Zaurus. Im not forcing anyone to agree with me or use this feature.
And what does that statement  mean that I can afford trashing my zaurus and buy a new one? I work hard earning doing my living and you better think before posting something stupid.

BTW, Is Guest your first or last name?

[maslovsky]

yes, this worked! so what does it do? 

Frank

This changes the refresh rate of the video chip from 100 (default in new ROM) to original 75.

You\'ll have to do that after every boot, so you may want to put this in a startup script, for example /home/QtPalmtop/qpe.sh.

Yes that would be a nice feature. Most important though is that the kernel must be compatible with both systems, because you cannot easily switch it without reflashing.  I hope to convince sash to keep X11 and Qtopia ROM kernels compatible, if not the same.

Changing root file system to point to a different location (removable media or any other place) is not a big problem.

strange thing: why does www.cacko.biz not say anything about this new rom?

where are the docs except here??? I\'ve never flashed my Z (bought wiht previous sash rom) so i really need to have a LOOOOOOOOOT of docs.

For exemple, why should i resize my partition ??
If i don\'t  like this rom, will the re partitioning be a pb
Can i reach network via usb

Any advice is welcome.

[jrsjkd]

when you download the rom there is a step by step instructions on reflashing in the \"read me\"  . youll need to repartition to 26 mb.  heres a quick recap...

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.

good luck !!!
