(simular messages are posted in different groups at windrivers... sorry if i bore you... still haven't find the sollution, only other victims).

When i insert the PC Card, the screen turns black and the computer reboots. It continuously to reboot, until i remove the PC Card.

Windows XP-home (Dutch), running on My Dell Inspiron 5100 (2,4 Mhz intel) seems to be incompatible with a 802.11G network card. (211G(+) Tornado PC Card (www.tornado.nl))

Other PC Cards work. I tried a 3com network card and another 802.11G PC Card of another brand (i don't know the brand).
The 211G works in other computers with a different configuration running the same OS (i think it was XP Pro.)

It is impossible to adjust the BIOS to not allocate IRQ's.

Searching the net, i found people with similar problems especially the compaq Evo 1020N.

Both Dell and Compaq use the Texas Instruments TI PCI-4410 as CardBus driver. Software driver is signed by Microsoft. Version 5.1.2600.0 dated 1-7-2001.
I re-installed Windows and updated in stages, continuously trying to install the PC Card. All XP and Dell-BIOS where (re-)installed.

Tornado is looking for a solution. They think the CardBusdrive software driver is causing the problem.
Dell doesn't support cards that don't work... if one works, the device works. (sic.)

I don't want to guide your search in the wrong direction, but... support text 295629 describes more or less the same problem. But this is a fix for problems with windows 2000.
