[tlinux-users 00413] Re: Qosmio G5-03M + 8GB RAM + Mandriva 2009.1 = only 4GB RAM found?

[Paul Wujek]

Thank-you HamRadio.

That is an option for using the 32-bit PAE extension to get 64-bit 
addressing in 32-bit kernels, and unfortunately doesn't apply because I 
am already using a 64-bit kernel.

There don't seem to be any BIOS updates for this machine, and I strongly 
suspect a BIOS problem because Memtest86+ cannot detect the additional 
RAM either.
