Thanks for the information - I'll have to take a look at the Tyan
Other than the serial redirect function, which as has been pointed out
previously is not part of the IPMI 1.5 specification, the SuperMicro
IPMI option cards are excellent. Sensor readout, motherboard logs,
watch dog timer, etc. are all readily accessible via the KCS and
ethernet interfaces. Like all IPMI implementations, it too uses a
separate discrete processor ("BMC").
