I can compile it. I suspect the code isn't SMP-compliant. Try forcing SMP=0 in Makefile.p4b, just to make sure this is the cause of the failure. Once confirmed, Mark D. Studebaker will take a look at it. > Here what setpci said: > > setpci -d 24C0:24C3 f2.w > setpci: Warning: No devices selected for `f2.w'. That's normal. The README.p4b file may not be really clear about this, but the -d parameter for ICH4 is 8086:24C0. 8086 is Intel's vendor ID, 24C0 is the PCI bus main ID, and 24C3 is the I2C bus (which we are trying to activate) ID. > Thanks for your fast respond, You're welcome. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
