Where did you find that? I ran strings over the file RG54G2_1_0_7_0.gzh,
but all I could find were a relatively small number of (compiler?) debug
msgs at the end. I tried renaming it to .gz and using gzip -d, but that
didn't work.

Here's firmware that works with the ISL3893 CPU - no idea if it will work
with this unit...


One thing I noticed is that the pads for the extra SDRAM chip are still
virgin gold (rather than solder plated) and there also appear to be SMD
support components for that missing chip installed around it. Might just
need the single chip soldered in to double the RAM.

Of course, that's little use if you can't hack the firmware... :)
