/usr/src/sys/arch/i386/conf/GENERIC:
#lm0 at isa? port 0x290 # other common: 0x280, 0x310
This matches the files.isa section:
# LM78 temp/fanspeed monitor
attach lm at isa with lm_isa
file dev/isa/lm_isa.c lm_isa
I believe this is the driver you're talking about here. I can't
answer the other questions, but I've used this driver on older x86
motherboards. Not recently, maybe P3 on 440BX.
