WLUG website on PDA web browser

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI gang, I recently got a Palm T|X and was using the web browser. It works fine for websites that are written in a certain way (mobile.palm.com, for example). Our WLUG website comes up with the WLUG graphical header but no useful text info. I'm wondering if it would be hard to format (at least the home page of) the website to display cleanly on a PDA (320x480 or 320x320) as well as a normal computer screen. Does anybody have the expertise and time to give this a try? If its a huge effort, it is probably not worth it, but I don't have the expertise to size up the effort. Thanks!

Re: [Wlug] kernel driver vs module

by Lee Keyser-Allen

The card that you are using requires that the firmware be loaded every time. Firmware, as you may know, is distinct from the driver that Linux uses to talk to the card ... it is the code that the card runs natively to control its operations and allow the card to communicate properly with (and pass data to) the PC. There are a number of reasons why they would load the firmware each time. I don't know this card or driver at all, so I won't bore you with conjecture, but the end result is that the driver needs to know where to find the firmware so that it can load it in, and get the card up and running. My guess, as to your question about redhat, is that the firmware is simply stored in a different location, or is linked into the driver directly. Again, having no intimate knowledge, I can only suppose. So, as you've properly ascertained, the driver can now get the card up and talking, and all you need now are some drives to have some real fun :). Hope that this helps, and good luck.

You're mixing up two different things. Almost all drivers which are shipped with the linux kernel can be compiled in one of two ways: into the kernel, or as a module which can be loaded/unloaded at run-time. So if you have a driver and compile it into the kernel, you should see some output from 'dmesg' showing you what was deteced on bootup of the kernel. Mike> My foggy'ness comes from a few things. Mike> 1. if the driver is built into the kernel, will it show up in lsmod? No, because lsmod only shows loaded modules, not modules which are available for loading.

One, it needs to match your running kernel image if it's a completely binary only module. Not a great idea in my book. If there is a binary core, but an source code wrapper section, then you'll need to compile the module against the installed kernel's headers. Not hard, the vendor should go into all these details.

It will definitely need kernel-source or kernel-headers, whichever your distro uses. You'll end up with a compiled module (name.o). I haven't actually dealt with adding modules in ages, but as I recall you put the resulting module file under /lib/modules/... appropriately (/lib/modules/`uname -r`/misc ?) and run "depmod -a". At this point the module should be all set. There's probably docs from the vendor as well. > This is a general linux quandry, but this time i have a debian stable install and have inserted a > QLogic HBA. lsmod does show qla2xxx, but it doesn't seem to be functioning as it isn't logging > into the fiber switch.

Vendor modules come in 2 flavors: binary only, and not binary only. ;) In the former case, you'll likely have to run the kernel version against which they built the module.

kernel driver vs module

by Mike Leo

I am still having a hard time understanding kernel drivers vs module's in practical use: I understand a kernel driver, is a driver that Linus, et al, have coded into the kernel, so if i have a peice of hardware, and I compile a kernel with that device's driver turned on, then my device will work. If i build that kernel driver as a module, the driver remains outside the kernel, but still availible for use. As a module I can rmmod or insmod when i need to use the device. My foggy'ness comes from a few things. 1. if the driver is built into the kernel, will it show up in lsmod? 2. if the driver does not show up in lsmod, how do i know if its loaded? 3. weather it's a built in driver or a module, how do i associate the driver (or module) with a particular device? 4. if the device does not have a driver in the kernel, I cannot build a custom kernel to include it, nor can I build it as a module from the kernel source. So: 5. if I get the driver from the vendor, it will build a module for me, based on my kernel-source or kernel-headers??? Then what? again, see #3: how do i associate the module with my device? This is a general linux quandry, but this time i have a debian stable install and have inserted a QLogic HBA. lsmod does show qla2xxx, but it doesn't seem to be functioning as it isn't logging into the fiber switch. thanks mike

CD drawer remains open

by Michael Long

Hi All, I have a system where the cd drive insists on keeping the drawer open. I will close the drawer manually by pushing the button that closes it. Within seconds the door will open again. What would cause this? Thanks

looking for an old amd cpu

by Mike Leo

greetings! I burnt out an amd CPU (my own fault of course...we all know how wonderful AMD chips are!)and am looking for a cheap replacement. It is for this motherboard: http://www.giga-byte.com/Products/Motherboard/Products_Spec.aspx?ClassValue… The current cpu is model AXDA2000DUT3C AMD Athlon, most likely http://www.cpu-world.com/CPUs/K7/AMD-Athlon%20XP%202000+%20-%20AXDA2000DUT3… however, if anyone has a replacement cpu that fits this motherboard and is willing to part with it, please let me know. Performance is not an issue, but working is a must! thanks mike

Mobile Phone

by mlong＠datalong.com

I am currently looking to purchase a mobile phone where I can edit open office documents, sync with my linux desktop, connect to the internet, create an access point and of course make phone calls. Has anyone had any experience with the linux based devices that are currently available or am I better off looking at some of the other os's. Thanks, Mike
