894mb RAM appropriated in BIOS?

[Fullmetal Chocobo]

I am setting up a linux box using a Asus P5L-VM 1394 motherboard and 4gb RAM (2x2gb). In BIOS (I haven't even loaded up the OS yet), it says it detects 4gb, 894mb are 'appropriated', and there are 3.2gb available? I know the issues with having a 32-bit OS and 4gb RAM, but I have never heard of an issue like that in BIOS...

Am I missing something?

I would assume that would be the amount of memory addressed to devices in your system but I would be wrong.

You probably have a kernel without HIGHMEM4G enabled which means you only get up to 896M of memory. If you install and boot from a 32-bit kernel with HIGHMEM64G enabled or an AMD64 kernel you'll get all of your memory.

I did some searching, and I've found that there is supposed to be an option in BIOS for remapping RAM addresses, but I can't find the option, even after updating. I'll keep looking though. I installed 64-bit Ubuntu server, so I'll see what happens. Thanks.
