With PAE, a 36-bit address is available, allowing access to 64 GB of RAM. What does not change, however, is that with a 32-bit kernel no single process can address more than 4 GB of RAM. > You'd also do better with Apache 2.0 or 2.2, as long as you use the "prefork" > version (which is more compatible with PHP, if that's your chosen "P").

Any pain spent transitioning from Apache v1 to Apache v2 or 2.2 is well worth it. > If your RAID card is one of the ones that uses a binary-only driver, ignore it > and use the open source drivers with md RAID instead -- md is faster than any > manufacturer's proprietary alternative (anything that needs a driver is fake > RAID.

If you look, there are drivers in the kernel for megaraid (Intel), cciss (HP Smart Array) and 3ware. All of there are certainly hardware RAID. In fact, all of those are also in the kernel and free software drivers, developed primarly by the hardware vendors. In any case, your statement is equivalent to saying "A true video card never needs a special driver; the card just shows up as a video device." *Every* device on the system needs a driver of some sort or another.
