Hi Bas

Unfortunately things work a lot different in our country. I'd like to 
take up your offer on the watchdog, but I know I won't be able to afford 
it, especially if you say I need to budget for it. Our currency is about 
8times the USD, so for USD100 I need to pay USD800 - which is a lot. And 
then we still need to pay for import duties, etc. Quite often, the 
USD100 components end up costing us about USD300's value.
P.S. What is IPMI2? Will it work on standard Pentium IV grade 
motherboards, or only on Xeon server grade motherboards? And does it get 
installed on the inside of the server, or how does it work?
