No, it's part of the base system. I've been using bktr _in_ kernel for many years (FreeBSD 5 and 7), but since 8.0, it does not build anymore. However, the module _does_ correctly build. The documentation is in "man 4 bktr". A typical use (with the PAL option, because I don't have "Never The Same Color" here), did work in the past like this: device bktr options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL options BKTR_USE_PLL options BKTR_GPIO_ACCESS options BKTR_USE_FREEBSD_SMBUS Today, I need to use /boot/loader.conf with those entry bktr_load="YES" Works for my Haupauge WinTV PCI video + tuner card, even the options (PAL) seem to magically work! :-) > I found that every loadable kernel module in the base system is, or at least > "was", rebuilt. That's correct so far. Additionally, all components specified by the kernel configuration file will be rebuilt, which in case of _no_ alteration is the content of GENERIC. As I said, there may be parts that one can safely drop (e. g. WLAN, floppy, ISDN or sound for a server). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
