Intel boards DG33FB is suposed to support 4Gb and more of memory and for that one will need a 64 bit OS.
Unfortunatly Intel has a bug in the bios that will prevent Fedora 8 x86-64 from installing or booting(after install) if the system has 4Gb memory or more. I belive the problem will show on a Win 64 OS too.
To install and run Fedora 8 -64bit, remove memory (2Gb works), or change to the 32 bit version of Fedora 8 but the OS can't use more then 4GB.
The problem can be described as an extremely slow system during instalation as well as at boot time after instalation, if one has 4Gb or more memory. Bios seems to be the problem but i tryied downgrading all the way to 0226 and still no resolution. Current bios 0326 still buggy.
Reported the probme to Intel, hope they listen.

You can use more than 4GB of memory in 32-bit Fedora if you install (after initial setup, of course, or during setup if you manually choose your packages) the kernel PAE version. All CPUs since the Pentiums MMX (I believe) support PAE or Physical Address Extension which will allow the CPU to address more than 4GB of memory (and up to 64GB IIRC), but this incurs in a small performance hit (some say it is actually negligible, but it is there). If the BIOS is the problem, wouldn't simple BIOS update solve the situation?

Have you seen this (http://www.suseforums.net/index.php?showtopic=39385&pid=202417&mode=threaded&show=&st=&) thread? I'm not sure if it will work or not but somebody claims to have a solution.
