Sharp ROMs / Ambicom 1100C-CF and Cacko rom v1.21b

« on: July 19, 2004, 05:18:40 pm »

So does anyone know where I can get a version of the hostap drivers with PRISM2_DOWNLOAD_SUPPORT and PRISM2_NON_VOLATILE_DOWNLOAD?   I need to be able to do the update on my Zaurus.

Zaurus - pdaXrom / WiFI 802.11b LAN Card?

oooooh so you need a access point router....

A Wireless Access Point is one way.

Another solution is through an adhoc network.  If you throw a wifi card into a computer that  already has access to the intenet you can use that  computer as a bridge and setup an adhoc connection.

5x00 Hardware / CF wifi card has trouble connecting to an AP

« on: April 02, 2004, 08:09:22 pm »

My card identifies itself the same and I have weird problems too.

In my case, after a reset of the zaurus I can\'t connect using WEP unless I first connect to something else using unencrypted.  After that, it works flawlessly.  It\'s got me puzzled a bit.

I\'m using the latest cacko release(1.20) on the c760 with the host_ap drivers.

BTW.  how did you get Kismet running, I have had no luck getting iKismet to work myself

For Sale / Wanted / buying z clam shell in australia

Try Conics.net,  I think they\'re based out of Australia and they have some of the best prices.

:::Edit:::
Oh, and they\'re a pretty big name in importing Zaurus\'s so the service and reliability should be pretty good.

Sharp ROMs / What Qtopia for the Cacko-Qtopia rom?

I\'ve found the above links to be unbearably slow.  
This link, however, is much faster:

Linux Applications / cpu mode

« on: January 16, 2004, 12:49:20 pm »

A couple of thoughts on this:

As lardman suggested, you should determine  a target cpu usage and attempt to keep the usage at or near this usage.  I propose you make this target usage user specified(Say, anywhere from 30% to 80%).


• One potential problem with too high or too low of a range is that you\'d either consistently underclock or overclock the cpu(Using Lardman\'s 100% example there would be no easy way to know when you should ramp up the clock rate and so the zaurus would gradualy slow down)
• CPU usage tends not to be continuous but rather spikes infrequently.  It would be nice if the program could ramp up the clock rate quickly.
please observe this psuedo-code for what I beleive would be a decent approach:

Code: [Select]

clk_monitor_and_adjust(cpu_usage, target_usage)

{

   if (cpu_usage < (target_usage - BUF))        // we\'re clocked to high

      change_clock(cpu_usage - target_usage);   // change clock speed down(negative)

   else if (cpu_usage > (target_usage + BUF))   // we\'re under clocked

      change_clock(cpu_usage - target_usage);   // change the clockspeed up(positive)

}



change_clock(scale)

{

   if ( (scale > 0) && (Current_Clock_Rate < MAX_CLOCK_RATE) )

   {

      // scale up the clock rate according to scale never exceeding MAX...

      //  and perhaps according to the history of scale

   } else if ( (scale < 0) && (Current_Clock_Rate > MIN_CLOCK_RATE) )

   {

      // scale down the clock rate according to scale never dropping below MIN...

      //  and perhaps according to the history of scale

   }

}

So what do you think?
