Progress update and INT2SD implementation request form!
With holidays starting, and more free time on my hands, I've decided to revive this project. Having my hard drive fail on me recently, and losing the request log, it has become obvious that I need a new system of handling requests, and it is here. If you have requested a ROM before, please send a request again, via this form.
Please submit all further requests via this form!

This is the INT2SD thread for Sense ROMs and their developers and users.
INT2SD thread for AOSP ROMs
What is INT2SD?
INT2SD doesn't use symlinks. It mounts ext partition on your SD to /data, thus eliminating the need for the mtd5 userdata partition. This makes the mtd5 userdata partition unneeded. It is used in conjunction with the fatsys HBOOT (more info later on), allowing most of the vital parts of a ROM to stay on the system partition without the need to symlink half of it to the SD due to memory shortage.
For now, there is only one ROM here, but more will come! If you wish to see INT2SD in your favorite ROM or in your own ROM, please post here!
INT2SD-S - "Speed" (default as of 29th Jun)
Main characteristics:
- /data on SD ext, /data/data on internal
- /data/data limited to 280 MB (probably enough for more than 100 user apps)
- noticeably faster on slower cards
- for use with CM7r2 HBOOT
Description:
The new "speed" flavour mounts ext to /data and userdata to /data/data, achieving great speed while still retaining excellent storage capabilities. It's used with the CM7r2 HBOOT. This is now the default flavour, offering great speed while still being able to hold a hefty amount of apps.
INT2SD-M - "Mass" (discontinued)
Main characteristics:
- /data on SD ext
- number of apps is only limited by ext size
- requires a faster card
- for use with fatsys HBOOT
Description:
The classic "mass" flavour mounts ext to /data, thus eliminating the need for the mtd5 userdata partition. It has proven to be slow even on some of the faster cards. Due to INT2SD-S being able to hold a very high number of applications, and still being much faster, this flavour is discontinued.
FAQ
For users: How to get this in your favorite ROM
For ROM developers: How to get this implemented in your ROM
Please fill out this form.
Cross-device implementations
For now, no. You may submit requests, but I won't be able to fulfill them for a while. I have quite a lot of real life work on my plate, not to mention a list of Desire ROMs I have to tend to. After that's done, I'll be happy to try blind-porting it to whichever device you wish, but my priority are Desire ROMs, primarily because it's a lot easier to implement INT2SD into ROMs for a phone I already have.
Universal update zips
Also, no. Each ROM is different, and due to the nature of INT2SD, it is simply not possible to make a one-for-all universal update zip. Every ROM requires tending to its peculiarities, especially Sense ROMs, and I would rather not take the change of trying to make one and end up with a flashable bootloop zip.
Why don't you just publish instructions on how to implement INT2SD for devs to use?
Before you download!
Although it is for the best part bug free, INT2SD is still a fairly fresh project so I'm looking for as much input as I can get to fix possible bugs I haven't yet uncovered.
If you try a ROM featuring INT2SD, please be sure to comment in this thread on your experience, even if it works great or doesn't work at all. If you wish to further support the project, there is a donate button in my signature. Although a nice sign of support and appreciation, donations are not obligatory!
Due to /data/data being on the SD, a high-class card is recommended.
Another thing is the HBOOT,
fatsys.
You must flash it before flashing any of the INT2SD Sense ROMs.

INT2SD Sense ROMs require a special HBOOT,
fatsys. This special HBOOT has 427 MB dedicated for /system, 5 MB for /cache and 5 MB for /data and there is probably no ROM without INT2SD that would work on it properly. It was made so that the largest part of Desire's internal memory can be used for quick access to vital system files by storing them in /system instead of symlinking them to /sd-ext, therefore slowing the entire system down. There is still plenty of space for your apps if you make a large enough SD ext partition, since SD ext gets mounted to /data and the real, 5 MB mtd5 userdata partition goes unused. So, /data on SD ext, huge /system and no symlinks!
Before flashing a Sense INT2SD ROM, make sure you have flashed the fatsys HBOOT!
