RE: [iPAQ] extending memory

Andre,

It is possible to extend DRAM to 64MB using densest SDRAM chips available
and Flash to 32MB using densest Flash available. These are surface mount
parts. The existing Flash and DRAM have to be removed to make room for
denser parts. The new Flash parts must be programmed with a copy of the
contents of the current flash before being installed.

I have good reports from someone who sent their units to the company listed
below to have the work done.
