I'm not sure how I can tell what piece of = hardware /dev/fido is linked to but I think you're correct and I'm using = the geode watchdog and not the winbond chip. Maybe this has something do = with me not having 'device eisa' in my kernel config! >=20 > I'm going to start compiling a new nanobsd image right now with eisa = and the newer wbwd.c driver and see how it goes.... Thanks You probably don't need eisa but if using my variant make sure you have = the hint enabled or the hints file installed/updated to include it. You should see the debug sysctls for the watchdog or it did not attach = and is not used. --=20 Bjoern A. Zeeb You have to have visions! Stop bit received. Insert coin for new address family.
