Is the E3's memory map documented anywhere? I've had a quick look back through the list archives and it doesn't appear on the Wiki anywhere...
I guess before I get too ambitious with the E3 I'd like to know what lives where. Is it possible, for example, to wipe out the PBL boot loader by mistake? And where does the Amstrad firmware fit in to all of this? I'm still using the example 'linux.pbl' file (or a derivative thereof) from http://the.earth.li/pub/e3/2.6.15/ . Is it possible to wipe out the Amstrad firmware to gain more space for custom stuff?
