I have a X58 board that also does not work, but in a different way ichwd module loaded ichwd0: <Intel ICH10R watchdog timer> on isa0 ichwd0: Intel ICH10R watchdog timer (ICH10 or equivalent) ppc0: parallel port not found. watchdogd starts up fine, but a kill -9 to it does not result in the box resetting. isab0_at_pci0:0:31:0: class=0x060100 card=0x4f538086 chip=0x3a168086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' class = bridge subclass = PCI-ISA cap 09[e0] = vendor (length 12) Intel cap 1 version 0 features: SATA RAID-5, 4 PCI-e x1 slots ---MikeReceived on Mon Mar 16 2009 - 14:01:57 UTC
