Dear Saifi, Thanks for the reply.
I know why it is giving LMC module loaded by PuppyLinux as I am using Sierra Air Card and in the lspci listing also it was giving the vendor id as 1011. But it is not able to detect the normal ethernet card which is there in the system. The same is able to be detected by SystemRescueCD (which is also in ISO format and I am running in the Virtual PC) and I am able to browse the net also thro' that. Both dmesg and lspci have not given any info regarding the ethernet card. Expecting your help in this regard. Regards Ravi Kumar
