No problem, I'm glad you could finally understand what was happening. In
fact, I remember a few similar reports of BIOS setup temperatures being
higher than under Linux. We knew that the idle loop in BIOS setup
screens were usually bad resulting in a slightly higher temperature. But
we had never seen a 20 degrees difference like you have. Maybe the idle
loop is particularly bad in yours (well, to that extent, I'd bet there is
no idle loop at all...)

Thanks for letting us know anyway.
