Hey Guys..
Disclaimer:
I've googled the list... and didn't see anything...
I've got a guy running an Asus A8V Deluxe w/Ath64 3000+ and 4 sticks of 1GB
and his setup (with either RH-EL3 64bit or RH-EL4 64bit) seems to be
exhibiting the classic x86/32bit problem of not being able to map the memory
around the 512MB PCI memory/chipset mapping. I'm not sure about the 2.4
kernel, but I would think that the 2.6 64bit kernel (or the motherboard)
could map that memory high (beyond the 32 bit range) to access all 4GB, but
nothing stands out on how I should go about doing this (BIOS seems void of
any such "settings", and I know of no OS/kernel (sysctl) parameters that can
do this).
And no.. Running PAE is NOT desireable.. This is a 64bit system.. why can't I
either map-high, or around the PCI hardware limitation?! (and NO.. I don't
want to add another 1GB to "get around it"). This guys wants 4GB.. Not pay
for 5 get 4.5.
Am I missing something here... or is this system simply NOT going to be able
to get to that last PCI mapped 512MB?
Anyone?
