Alright, I'm going to make this thread to keep some of the info organized on it so that everyone who wishes to install it can go about it easier.
And I'm also going to include a mini-FAQ about it so that we don't get the redundant questions as often about it.
Q - Can I install FMCB with a PC/PS3 and a memory card adapter?
A - No. The FMCB installer requires the PS2 for it's built in MagicGate support as well as it's DVDPLAYER ELF file in the BIOS.
Q - If I install it on one region system, can I use it on another?
A - No. Once installed you can use the memory card on another region system, but Free MC Boot will not work on any system that is not the same region as the one you used to install it.
Q - I have a SCPH-9000x system. Why is it not working once I install it?
A - Sony has removed the DVD Player's upgrade feature within the BIOS on the newer versions of that system. FMCB requires that this function be active for it to work as FMCB hijacks that feature to operate. Note that SCPH-9000x systems that have a BIOS revision older than 230 (or the system has a date code older than 8B)
Q - Can I play backups with FMCB only?
A - No. You have to install ESR with it. Make sure it's in the INSTALL folder of the installer package. Also, you have to patch your ISO files before burning them.
Q - Can I add more apps to the main menu?
A - Yes. read the tutorial.
You can find the TUTORIAL HERE: bootleg.sksapps.com/tutorials/fmcb/noobie.php
I'm only linking to it since if it needs to be updated, JNABK or my self can do so by updating it in a single location instead of mulitple places.
Tutorials include the main body of information on the installer as well as methods to boot up the installer on completely unmodified systems.
Also, I'm including the current release of FMCB, uLaunchELF, and ESR, and the ESR patching utility (current as of Dec. 22, 2008) so that users can get a foot in the door on homebrew and the ability to save their original games from wear and tear.
FMCB - Primarily jimmikaelkael and neme
ESR - ffgriever
uLaunchELF - Primarily dlanor and E P
ESR patcher - not sure. no one documented that one by any read me or any of the source files.
