New Ideas For BIOS Hacks
« Reply #180 on: September 03, 2003, 02:42:00 PM »

As Chinmi said in an earlier post, password-on-bootup would be nice.  Okay, so you can do it with an xbe, but this won't stop you booting games (or booting an Evox installer CD and removing the password xbe).  In the BIOS is more secure, if your Xbox gets nicked you can at least relax in the knowledge that the robbing bastards have gained no more than a big doorstop (unless someone reflashes or fits a new mod, but any reputable installer ought to refuse to do so unless the customer can prove ownership).

This one should be relatively easy to implement, as the Xbox already knows how to read it: the ability to format the F: drive using GDF instead of FATX, thus overcoming the 42-character limitation without having to resort to the Avalaunch method (not that I'm knocking it) or having to squeeze in NTFS/FAT32 support.

make the bios look for a dashboard in the F: or E: drive! so ms cant see it, and youll have an untouched C: drive smile.gif

Ummmm.......
I don't know if you're joking or not, but that already exists.

480p bootscreen, if its at all possible.  Most VGA users can't properly enjoy their custom bootscreens.

I know exactly shit about what the bios can and cant do, but how about this ( if it is even possible... ).

  How about a BIOS that can tell if the outgoing network traffic is local ( system link ) or now ( LIVE ), and if it is LIVE then don't allow it, ( Games should just display the "Can't reach live" message, and M$ can't ban your modded box cause they dont know it exists... )

Call me stupid, but it was a good idea I thought so be nice...

Now that we have an XBE in the bios and we can read if a button is pressed... I would like to see the XBE loaded on a 256KB partition.  This would allow us to use FlashX to flash a new XBE to the ROM... As modchips advance and the sizes grow, the XBE can get bigger and/or we could flash multiple XBEs to the ROM - mini-dashboards, FTP, BIOS defrag, etc...

The thing about this is that you can't just have an XBE in a BIOS bank...you still need a kernel that can dictate the primary functions of the XBE, and to get the kernel and an XBE inside of 256K would be a pressing task.

QUOTE
Along the same thought, why not allow us "simple" mod-chip users (X2 lite, Matrix, cheap-mod, etc) the ability to have multiple BIOS selection.  This could be done by flashing a different 256KB BIOS to the 2nd half of the 512KB bios bank.  By pressing a button on boot, the code would finish execution by loading the 2nd 256KB instead of the 1st 256KB. X2 lite users would then be able to have four 256KB BIOSes (or two 256KB & one 512KB) on the mod chip... it also seems possible that the BIOS could halt and wait for one of four buttons (like press F1 to continue) and then attempt to load any of 4 possible 256KB BIOSes.

What you're talking about doesn't have anything to do with the BIOS - it has more to do with either making a change to the X2.x hardware (a change present in the X2.x Pro family) or hacking the MCPX (to only download 256K from a starting point in the FlashROM...then halting).

The biggest feature would be an X2 BIOS that allows you to boot from DVD, REGARDLESS of the state of the hard drive or dash files. It should also have an option to "fix" the clock if it's invalid. This is one of the biggest flaws in the current X2/X3 BIOSes out.

how about a tool like XBtool that could inject a xbe into a bios. using that you could posibly put the whole evox dashboard in the bios, and with the tool to inject it in there you could put your own evox.ini file in there. i whold love that  beerchug.gif

Yes, I would love to see that.  That would be deserving of a 1mb BIOS.

i think your forgetting what a bios is... Basic Input Output System.  Keep in mind BASIC... this is comparable to wanting your Windows (or whatever operating system) loaded into your bios on your pc.  In all seriousness, it's a bad idea to even want to... imagine editing your "evox.ini" file on your xbox and the power goes out...bye bye bios...lmao

I would totally love to see a boot sequence, so u can choose from dvd or HDD.

reason why if u have a toast hdd, boot the xbox via dvd so u can ftp over to xbox and just maybe be able to save a few files on it.  this would be a huge help.

uh...you can ALWAYS boot from dvd, by putting a disc in and powering it off then back on.

Not true man, It usually works that way, but for alot of people that feature does not work.  DVD booting first always is critical.

unless a user has modified the bios to boot from a different file that the default.xbe off disc, it will boot to the dvd, please show me otherwise, as I don't believe what you are saying at all.

Um, I guess you don't understand the problem (though it's been described many times).

Lots of people cannot boot to DVD with "new" hard drives using X2 BIOSes. For some reason, the X2 hangs because it is looking at the hard drive, which isn't formatted yet. I don't know if this is 100% consistent, but it DOES HAPPEN. This happens if the unit is powered up with a disc in or if the disc is inserted afterward.

The end result is that it's impossible to "install" a new disc drive using an X2 BIOS. It never boots the DVD/CD.

Team Xecuter is working on the problem, though, so hopefully it will be solved soon.

Without creating a duplicate set of routines for a "FATY" for example, and using that on F: and G: to hold games (while using the standard FATX routines on C:, E: and the temp partitions), I think the task might be a bit out of reach for now.
