Hi, Jan, and apologies for the late follow-up; been quite busy... On 07/12/10 06:38 am, Jan van Wijk thus wrote : Hi all, As some of you may heve noticed on several lists, I got myself a new Thinkpad W500 a while ago, to use with Windows mainly but in the hope to use it as well as possible with eCS too. (since my T42 was slowly dying on me :-) Sorry to hear about your T42 reaching EOL. I've decommissioned a number of T30's recently, myself, and luckily, the T43's in the field seem to be holding up. I have eCS 2.0 GA running on that machine now, with a usable display in 1680x1050 (panorama). Great! The wired NIC is being worked on (new gigabit driver) but does not work yet. The latest build *should* work for you. The wireles (an Intel 5300 AGN) does not work of course, and support by Genmac in the near future is quite unlikely. Indeed. That leaves open one more posibility to get wireless: swap the card for one that IS supported in eCS (and downgrade the windows driver too :-) :-) I have an Intell 2200 as well as an Atheros card available (both from T42's) so I was investigating the effort to put one of these in the W500. The downloaded HW-manuals (T42, W500) seem to indicate that these cards are NOT compatible, not even in physical dimensions/shape! The ones for the T42 have the miniPCI along its long edge, while the 5300 card from the W500 seems to be smaller alltogether, and has the miniPCI connector on the short side of the board. Seems to be a different 'miniPCI' to me :-( See the attached JPG's, taken from the HW-manuals. Anyone know for sure, before I start disassembling my W500 ? Per Aron's comments, the W500 has a mini-PCI-Express slot and the T42 has a mini-PCI, which are different architectures. Look for an Intel 3945abg (8086:4227) or a 4965agn (8086:4229, or 8086:4230) card to replace the 5300 in the W500. I have tested both of these with GenMAC with good results. The difference is really whether you need the 802.11n capability now or anticipate needing it in the future. I *believe* the 802.11b/g & 802.11a radios in both cards are about the same, at least in terms of performance (someone please correct me if my recollection is lacking). Also note that the 4965agn card supports *draft*-n, as it predates the ratification of the 802.11n standard. Thus, it may not be fully compatible with equipment which has been released more recently.
