Hi, I have install 4Gb of ram on this HP Pavilion dv6000 laptop:

The BIOS showed only 3Gb of RAM.

Then I have update the BIOS with last version released from HP.

Now the BIOS show correctly 4Gb of RAM, but Fedora10 x86_64 show only

3Gb of RAM (also smolt show 3Gb of RAM):
[root lesca ~]# free
             total       used       free     shared    buffers     cached

On this laptop I have test also Fedora9 with last kernel-PAE-x.x.x.i686
but also in this case the memori show is only 3Gb.

Some suggest?

Is a BIOS problem?

No, you need to turn on the PAE abilities in the kernel config and re-build & re-install.

On an x86_64 system? x86_64 is supposed to work without PAE. Check your BIOS.

Thanks for reply.
