Why FC3 doesn't see 4Gb of RAM?

[Andy Pieters]

IIRC, you need to use the hugemem kernel!  I don't seem to remember there 
being a combination of hugemen and smp, but that can be resolved by doing a 
compile-your-own-kernel, which isn't so hard after all.

I managed to compile my own kernel after only one month of Linux conversion, 
and I am sure, others on this list can give you usuable pointers on this.


With kind regards


Andy
