Here three unknown Sharp ICs are shown.
Two chips marked as
SHARP
50752B26B2
F0703T588
and one marked as
RX-IX0032YCPZQ
I've found almost nothing about these chips on the net.
What can it be?

C1000/3x00 General discussions / C3200 Boot Process

Hi. I'm very interesting how zaurus boots up.
What does happen when power is applied?
There is no information about internal flash in PXA270 datasheet. So where is maintenance menu (and rescue mode) code located? What does handle special key pressing?
Unfortunately, I haven't found any really useful information.
