RE: [iPAQ] Battery Life, Flash Writing, etc...

Thank You kindly....I forgot that they have been changed...

For future reference, where is the best place to look to see what the current partition numbers, locations and sizes are?

Linux/Kernel...
drivers/block/flash-mem.[ch]

Or is there a better place?

If the lk source is the best place, then what type of device is the ipaq (there are a bunch of if-defs in there)...

Remember, not all of us are kernel hackers....
