Android's AutoExec equiv. (to launch a web site's Home page)?

So, on another Op Sys, an AutoExec file
- at the top of a cdROM'S file structure -
could be used to open an HTML page, to
display a list of that disk's contents, etc.

Is there an Android-specific counterpart,
preferably, one that works across all
versions of Android?

Tnx

Other sites like XDA for ROMS and such..??

Do you guys use other sites similar to XDA for flashing roms and stuff, or is this pretty much the lone ranger when it comes to doing what we all do here..??

Thanks
