I have now an easy setup after a complete MEMORY LOST. I connect over the PIL Box to an IL-Drive and load an Autorun/Program.
After 2 minutes my CL is configured as OSX3 with WARP, RAMBOX etc… and all RAM Pages are filled up with the PRGM-STORE’s.

Great!

Flash does not work like RAM, I am at the office right now and cannot give you the exact procedure but here is the pseudo code that you need to do.

1. copy Flash sector (64K) into 8 continuous RAM pages (ex.: 0x810..0x817)
2. update RAM pages (4K) that need to be updated (ex.: within 0x810..0x817)
3. erase Flash sector (64K)
4. copy back the 8 continuous RAM pages (ex.: 0x810..0x817) into the newly erased Flash sector (64K)
