First, start with:
www.linuxfromscratch.org
As for understanding the early boot process, this is probably a bit dated by
now, but it's what I learned from:
http://www.tldp.org/HOWTO/Bootdisk-HOWTO/
I'm told it's been replaced by this, now that floppies are passe:
http://www.faqs.org/docs/Linux-HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html
To understand the theory behind it all, the best resource is a touch out of
date (2.4 kernel) but still good. Chapter 1 (booting) for tigran Aivazian's
"Linux Kernel Internals":
http://www.faqs.org/docs/kernel_2_4/lki.html
The big things that have changed since then are that the boot sector at the
start went away (you now _have_ to use a bootloader like lilo or grub), and
initramfs got spliced in as an alternative to initrd (and initrd will
eventually be deprecated).
For PXE, this might have something useful:
