今天把r50上的B卡换成B/G的以后，屏幕上的无线灯不亮了

jarlflcr

是INTEL的B/G卡，用了1802补丁，可以用了，CTRL+F5也正常，就是屏幕下的那个无线灯怎么也不亮，有人知道怎么弄吗？

后来我启动到BIOS里,用PCDOCTOR,根本检测不出无线网卡.只有在XP下才行.我怀疑是这个问题,请问该如何解决啊?

和我的T40一样,我的是INTEL2915A/B/G卡,F5正常就是灯不亮,开机没蝴蝶.

楼上的问题可以刷 BIOS解决。
楼主的问题一般无解，INTEL的卡就是不支持无线灯，其它都正常，看看坛子里的帖子就知道了

我的已经是最新BIOS了.

好像不是吧，我的T43原装就是intel的BG卡，一切正常啊。

我估计可能是1802补丁造成灯不亮。1802补丁是取消主板对无线卡的检测使其可以使用。国外网站已经有办法修改无线卡的信息使主板认为其和ibm原装卡一样。但需要在本本上安装linux操作系统进行。转载如下，供参考。


Okay guys, I have a version of linux (Knoppix) on a boot CD up and running on my laptop, and can build the drivers required to write to the 2200BG EEPROM!

I was thinking that putting 0x03 in byte offset 0x4A in the EEPROM would turn it into an IBM card. As this is how the driver works out the OEM card version, so I did that.

Unfortunately that doesn't work, so don't try it! In fact it completely screwed the card so it wouldn't even boot under linux or Windows - so basically I couldn't even use ethtool to set it back again! Eventually I managed to write to the EEPROM by adding some custom code to the card initialisation routine. Phew!

Does anyone have an official IBM (or any other OEM for that matter) 2200BG card which we could dump the EEPROM on? Then I can see what else is different other than the PCI ID and NIC Type?

Here's how to do it:
Download Knoppix LiveCD from http://www.knoppix.net/
The version you want is KNOPPIX_V3.8.1-2005-04-08-EN.iso
Burn this iso image to a CD (Note you must use the disk image option of your CD burning software, not just put the iso file on a data CD)
Boot your computer using the CD - Hopefully it will auto-detect all your hardware (just press enter at the boot screen) and eventually arrive at the desktop. Neat eh?
Click on the penguin on the taskbar and select "Root Shell", then the following command (from now on any line that begins with a # is a command to be typed at the Root prompt:
#iwconfig
You will get a list of ethernet adapters, eth0, eth1 etc. The wireless one should be quite obvious from the text displayed after it with all the wireless parameters!
#ethtool -e ethX
Obviously replace the 'X' with the index of your wireless card you found above.
You will get a hex dump of the 256 bytes of EEPROM data. Post it here, you may want to remove your MAC address.
Note: There is nothing dangerous in the above steps at all.

If you want to writing to your EEPROM (You can seriously screw your card up - as I showed - so don't do this unless you know what you are doing!):
You will need to download the linux kernel sources for 2.6.11 and make them. This is what I did. Note you will need to be connected to the internet via the onboard ethernet:
#cd /usr/src
#wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.11.tar.bz2
#tar xvjf linux-2.6.11.tar.bz2
#cd linux-2.6.11
#make xconfig
Select save and exit on the GUI config screen that pops up
#make
I'm not really sure if the last two steps are 100% correct, but they enabled me to build the ipw2200 module that I needed in the next step! Note the last make takes quite some time, but you don't seem to have to wait for it to finish!:

Next you will need to download the ipw2200 sources, patch them and make that:
#mkdir /usr/tmp
#cd /usr/tmp
#wget http://mesh.dl.sourceforge.net/s ... 0/ipw2200-1.0.3.tgz
#tar xvzf ipw2200-1.0.3.tgz
#cd ipw2200-1.0.3
#wget http://stachon.webpark.cz/files/ipw-eeprom-write.patch
#patch -p < ipw-eeprom-write.patch
#make

Now you can unload the current ipw2200 module:
#sh unload

And reload your new one you have just patched:
#sh load

You can view the driver debug output:
#dmesg
Which is really useful if you have problems getting it to load.

Now you can write to your card EEPROM as specified in WhiteHeat's post, and Druid_cz's instructions here

楼上的兄弟你的卡是IBM原装的当然一切正常了.

micc

零售卡按国外网站的说法修改识别数据后（类似MAC地址，写在卡上的EEPROM中）和原装卡完全一样。不知那位有时间实践一下，造福广大黑友。

灯亮不亮，是电路监测的问题，与bios无关。 [/quo
能解决吗？

wzffree

呵呵，这个灯亮不亮很重要吗？用FN F5看一下点开启就行了，能用无线的话就挂个QQ，如果QQ没掉线就是好使，这不比硬件还得快？



                                                所以，不必强求。

williamszhao

把这个顶上去啊
那样的话就可以把非IBM的卡改成原装的了

qingdaoyaboo

我已经改完了，用的是DELL拆机的2200BG全高卡，就是灯不亮，其它都很好

msvcp60

用原装拆机的或者全新的，没问题。。。
