Once you are registered (made the purchase, so to speak), you can come back and download at any time. I got in on the last round and have downloaded OEM, Developers and Live several times since. If you can be patient, once the promotion is over download times improve greatly. Make sure you get a good download of the iso before you burn. My first burn appeared to be good but Lindows refused to identify my video. I ran live with no problems and then tried a new download of Dev. Ed. burned at 8x and voila (thats French for Hot Damn!) it worked like a champ.
I am running a take over install on an old 20 Gig IBM HDD connected to a K7-810LMR motherboard(all in one Amptron, SiS 730 onboard graphics) and a 1.2 Thunderbird cpu. Lindows found everything including my NIC. I am impressed so far. It is just tough learning a new system.
I am going to try to get a DLINK 802.11a pci card to work next. I hear that there is a driver called MADWIFI that will work but have had no luck locating a download on the net. Any help with this would be greatly appreciated.
