George, >What do I try to clear up the mem conflicts for pcic next? I'm tempted >to try leaving it to the kernel to find these and not wire it to 5, but There are two memory addresses associated with pccard. One seems to be the address used by the controller, and the other to be the address used by an inserted card. /etc/rc.conf (overriding /etc/defaults/rc.conf) pccard_mem=0xd8000 default is 0xd0000, which is great if no other devices on the PC decide to use this memory area. 0xd8000 leaves some headroom for those other devices. This seems to be the controller address. /etc/pccard.conf (overriding /etc/defaults/pccard.conf) memory 0xdc000 64k default is 0xd4000 96 (I just made this new value up, since the default is 0x4000 more than the previous default) This seems to be the card address. These are the values you have to play with. And thankfully, you can keep changing them without recompiling the kernel. Although you may need to recompile once to remove an existing "iomem" specification for pcic. No need to change an IRQ to test this. The values are independent. Good luck, Greg P.S. Did you try Windows yet? That may shed some light on special memory addresses needed. It was what got my first FreeBSD laptop going, due to the pccard controller using an odd port address. At the least it will be informative. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
