[Gta04-owner] New SD card setup

[Neil Jerram]

Hi all,

I'm about to setup a new SD card and am wondering about the detail of
the partitioning instructions.

The README at http://sourceforge.net/projects/qtmoko/files/GTA04/ says:

> * You need specially partitioned SD card. The partitioning is described
>   here: http://code.google.com/p/beagleboard/wiki/LinuxBootDiskFormat 

and that beagleboard link includes a section called "Set the Geometry of
the SD Card".

My question is whether that section really matters, and if so why.
IIRC, I followed it when setting up my last SD card, but then I found -
when printing the partition record again - that all those changes hadn't
stuck.  I.e. the numbers of heads, cylinders etc. had reverted back to
what they were initially.

Can someone explain whether and why those instructions are needed?

Thanks,
        Neil
