Re: SuperMicro X6DHE-XG2 + 2x Irwindale in 2.4 SMP

[Frantisek Rysanek]

Dear everyone,

it seems that there is one BIOS SETUP option that escaped my 
attention: in the BIOS version 1.3a, it's called the
"C1 enhanced mode".
In order to make Linux 2.4 work on the SuperMicro boards with 
Irwindale CPU's, this toggle has to be disabled.
