Since the T40 usually comes with 802.11a/b cards (no Linux support), we are getting these systems without wifi cards and were hoping to put prism2 based cards in them. ("IBM High Rate Wireless" IBM:22P7701, stock card in T30's) The bios locks the system with this nasty notice: ERROR 1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card. if you boot with either: a) an "IBM High Rate Wireless" (22P7701) (T30 wifi prism2) b) an "Broadcom BCM4301" (802.11b/g unsupported) It's clearly just an artificial BIOS limitation since we can swap the card in while waiting at a GRUB prompt (!) and it works perfectly. This implies that IBM has decided which cards to _allow_ users to put in their laptops, and in the process is rendering these T40's unable to have working wifi under Linux. ( preview TPCA ? ! ). We have of course updated the v1.03 bios (1RET32WW) to v1.04 (1RET33WW) to no avail, and searched IBM's site which revealed only the same "Error 1802" translation that the bios gives. What the Linux community needs from IBM is a BIOS update that does not cripple these systems. Does anyone know of a BIOS fix or other workaround for this problem? It seems uncharacteristic of IBM to simultaneously ship the machine with an unsupported card, and retard the system's ability to boot with a working card. Feel free to call or email me directly if need any more tech details. -- Lincoln *------------------------------------------------------------------* | Lincoln D.
