Okay... Took a flash card and downloaded OpenZaurus and OPIE...
Took the image labeled 64-0 and renamed it "zImage" as per the instructions.
Took the opie image and renamed it "initrd.bin" as pepr the instructions.
Got both files from
www.openzaurus.org ... That seems like a reliable source.
Those were the only two files on a known good 256MB SanDisk CF card.
Held down "C" and "D" and pressed Full Reset.
Both the mail and power lights were on for a few minutes, then they turned off...
Removed the Flash card, Hit Full Reset again, and closed the battery door.
My SL-5500 now says "Sharp" in red letters and has a blinking cursor in the lower right corner of the screen... No booting. Sits like that for maybe 15 minutes and then shuts down.
What'd I do wrong?
