Hi,
I've just installed LegOS 0.2.5 and its working great! However, I'd like
to temporarily put the original lego firmware back on. How do I erase the
legOS firmware so that the ROM bootstrap code will permit the Mindstorms
software to download its firmware? I've tried removing the batteries (while
the power was still on) but to my surprise the memory wasn't cleared (even
after over 24 hours!). I've got the RIS 1.5. Is there some OS function to
reset the RCX to boot-mode? I'm amazed that leaving the batteries out doesn't
clear it. The RCX doesn't use FLASH RAM does it?
Thanks,
Rick

| Ok, big surprise: it turns out I'm a moron. It was cleared all along, for some strange reason I was expecting the "00:00" to come up in boot mode - I forgot that was part of the Lego firmware, not the boot code. I guess thats what happens when I (...) (24 years ago, 14-Feb-01, to lugnet.robotics.rcx.legos)
