BIOS setup needed for LBA48?
Hi.
Let's assume a certain IDE controller does LBA48.
Let's at the same time assume the BIOS doesn't know jack about LBA48.
Let's then assume that I can get a kernel to boot on it, what method I use doesn't matter. The BIOS doesn't lock up or anything but it doesn't use more than the fabled 137GB.
Can the Linux Kernel then use the full drive (160GB/250GB/whatever) even though the BIOS doesn't? (LBA48)
That's question number 1.
Question 2: Does the nForce chipset handle LBA48?
They are related but please answer question 1 even if question 2 is "no" :)
I tried looking for the answers myself but couldn't find a definite answer. If it's plain in sight somewhere, please point me in the right direction.

Usually, yes.

Usually, yes.
Is there anything that could make "usually, yes" become a "no"?

Usually no.

Yes, if the host controller can not handle the double pump for dma operations. Disable DMA int it has to work. If it does not, you have a nice pile of junk, and it should be come a door.
