We have already featured the SpeedMod Kernel for Samsung Galaxy S I9000 and you can find most details there as this version is practically identical to that one when it comes to features. Just to give you a couple of highlights, this kernel is known for its stability, speed, compatibility with stock and custom ROMs and high battery life. It works with Android 2.2 and 2.2.1 ROMs.
The installation method is also identical to the one used in case of the Samsung Galaxy S I9000. However, the kernel file used is different and is specific to the Samsung Captivate. Do NOT attempt to flash the Galaxy S I9000 version on your Captivate. Instead, download one of the kernels from the link given below and flash them to your device using the procedure used for the Galaxy S I9000 here.
Once the kernel is installed, you can get best performance from it by enabling all tweaks from the recovery menu under SpeedMod features. In case of any issues with the installation, refer to this page at the developer’s website for some workarounds or visit this thread at XDA-Developers forums.
