boxorox: It says "Ignore Hard Drive Partition Table" and if you don't understand what it means then you probably won't ever use it. So it doesn't really matter which one you choose, just leave it in default value.

Ozpaulb: Could you release some info how to hex-edit own partition tables to HD?

Dude, don't feel bad, I missed that too.  That drop down arrow is small and the scroll arrows to select the options is even smaller.  Especiall with 1280 x 1024 resolution set on my pc.

There's no need to modify evox.ini if you're only going to use drive F:. If you want to add drive G:, you'll have to wait until I've released my patched version of the EvoX dashboard (with G: support).


boxorox: PaulB needs to release a patch still if you want to utliize the G drive in Evox.. 

I think I may beable to do it with MXM.


BenJeremy said he will support the G drive in the next MXM release as well as formatting of that drive but as of right now, neither MXM nor Evox supports it....YET!

Paul,

Thanks for this great new hack!  I have a homebrew 29 wire mod that I'm updating today from an old bios version to a more current one (4977) and I'd like to put the large hard drive support on it as well since it's a pain to reopen my xbox and get to the mod.

My hd is a 120gig at the moment but I anticipate changing over to a 300 in the near future hence adding the large hd support.

My question is, will enabling lba48 create a problem for me when I use it with my 120gig?  When I made the 4977 bios I chose the "Partition 6 takes up the rest of the drive" option as I don't need drive G on my existing small HD and the new HD when I buy it.

Again, thanks for the great new feature.

no, select partion6 up to 137GB / partition7 takes the rest

Thanks, I know that already.  There is another selectable box, besides that, that is called "Ignore hard drive partitions".  
I don't think I should select it but I want to be sure. wink.gif

The "ignore hard drive partition table" option won't affect anything until we start seeing programs that write a partition table to the hard drive (since I'm the one who is defining the partition table format, I assume those programs won't come out until I release info on it).

As I've said before, I personally feel that you should NOT check the 'ignore' option.  If you don't have a partition table on your hard drive (which NOBODY (other than myself) has right now), then it won't have any effect.  If, in the future, some 'partition editor' program comes out that allows you to edit/move/resize partitions on your hard drive, the 'default' option in the LBA48 bios is to pay attention to those changes.  I think that the 'default' option should be the 'normal' option: pay attention to any (possible) paritition table on the hard drive (allows most flexibiilty).

If you check the 'ignore' option, then any changes/additions made to the hard drive's boot-sector partition table will be ignored.  This means that if a 'partition editor/resizer/etc' were to be released in the future, your bios wouldn't recognize those changes.

I think the only reason to 'check' this option is if you've written a 'bogus/garbage' partition table to your hard drive's boot sector.  'Checking' this option is a safeguard - no matter what (bogus) info is written to your hard drive's boot sector, it will be ignored/the 'default' partitioning will be used.  Again, it really should only be an issue if you've written a 'bogus' partition table to your hard drive.

But, as I said, since NO partition table tools have been released yet, it really makes no difference (for now) what you select for this option (since there is no hard drive partition table, it will always just use the built-in/'default' partition table - no matter what you 'check' on this option).

I hope this clarifies things.

If your hard drive is < 137GB, then my LBA48 patches should have NO effect (other than allowing for partition tables, which default to the same as EvoX).  

Once 'enabled', my LBA48 code still uses LBA28 commands to the IDE device unless the sector number of the hard drive is >= 0x10000000.  Since drives <= 137GB don't have sector #'s that high, then everything will remain LBA28 (old style), and should be 100% compatible with existing drives.

I hope to release this info in the next couple of days (YES, I know I keep saying 'in the next couple of days', but I've been busy @ work/haven't had time to finalize this stuff).

Paul,

Thanks for the reply and I thought I'd check in with my findings...  I used the 4977 bios with the "Partition 6 takes up the rest of the drive" option.

I installed it into my xbox with 120gig hard drive and all is well.  I copied a new game to the drive and I'm able to run it from there no problem.

So, no problems over here.  Now I gots to get me a 300gig drive.  Who needs to save up to buy a house anyways...

Quick question (I've skimmed both the other thread and this one, but may have missed it if it was mentioned): regarding the cutstom drive partition table: does this mean that we could potentially (when the tools are out there) have two partitions for c: and two partitions for e:, one set of which would be unchanged from retail and at the normal positions and one set of which would be loaded when the mod was enabled?  That way, when we disabled our mods, even if the new Live did a check for homebrew saves, they wouldn't be there since they'd be on a different partition that wasn't currently mounted as e:.

oz_paulb, first, congratulations on pulling off the "impossible" smile.gif

Yes, it will be possible to do this.

It doesn't mean that MS can't detect the situation, though, since they can read the partition table, too.

Has any one recovered their 23gb of a 160gb drive yet. (in the form of a G partition)

I sure have.  I patched 4977 and used Avalaunch to format the G drive.  Paul is working on a patch for evox, but until then, i'm using avalaunch as my default dash.

biggrin.gif  well im damn glad i didnt go out and get that 120GB drive i was gonna get.

Does this work on all versions of the xbox (1.1), modchip (mines a x-ecuter 2 lite), and dashboard(evo-x 1.8.3752)

Sorry if this has been covered but im very conscious of screwing up cus i seem to be so damn good at it.

Thanx
