If you are new to OS development and think that this FAQ lacks information on some area, you could post your request for more info here:

A comprehensive guide to setting up paging, physical, and virtual memory management.
An article on memory management. Review Solaris slab allocator, what is a buddy system, how Linux does it, overview of the NetBSD uvm, etc. -- this is partially started in Page_Frame_Allocation.
The most important thing an OS does: load and run programs. Using PIC with ELF programs, loading and running Microsoft COFF-in-PE files (assuming they are not Win32 programs of course; link to MSDN "Inside Windows" articles on PE), link vs. load addresses, etc. Also loadable kernel modules (for monolithic kernels): how do the modules find the kernel symbols, etc.

Device driver interface, how to make/use one.
More on hardware programming. Demo ATA disk driver, demo ATAPI CDROM driver, or commentary of these drivers in Linux or one of the BSDs (or even Minix v3 http://www.minix3.org).

File systems. A look at traditional file systems on Unix systems (e.g. the v7 file system), then move on to the BSD FFS, a look at FAT12, FAT16 and FAT32, a look at modern Unix file systems like Ext2 and journaling file systems (NTFS, Ext3, ReiserFS), implementing a journaling file system.
more info on C heavy grub booted kernels (particularly at&t syntax asm style...).
A map of the BIOS data area (like http://www.bioscentral.com/misc/bda.htm)
Information on the theory behind command lines and text UI's.
Naming OSes - http://www.osdev.org/phpBB2/viewtopic.php?t=15250

This has been sort of started in Beginner Mistakes. Yayyak 23:18, 26 October 2007 (CDT)

Adding new object format to BFD (this is discussed in http://libosdk.berlios.de/wiki/index.php/Binutils).
Coding a delay(ms).
More on C++: what support is needed to fully use C++ in a standalone environment? Why? Example code?
C library stuff: examples of crt0.o and crt1.o (or crtbegin.o, crti.o and crtn.o whatever!) and what the purpose of these files is.
Some notes on the newer devices like HPET timers -- see this thread.
