Thanks, TTAV134 for the quick reply! Ok I'm gonna flash my other laptop now. Bummer the dv6t select edition isn't supported yet.... I hope hp just add the 6250 WiMax card in the BIOS' whitelist, otherwise I just bought another useless card Some say in another forum that the card will be supported, but I doubt the wireless card from an Alienware MX laptop would work on the hp even if the exact wifi card model is supported in the whitelist....
TTAV134, could you send me a copy of the patched iscflash.dll file? I have a Pavilion dm4 model and it seems that it suffered from the same problem.
Anyway you could try: Remove power cord and battery...wait....plug in power cord, switch it on, try to enter bios setup....try with battery second time.....check all plugs.
