Want a FAQ for Medley

what's the difference between lde and ldex

In practical terms: If you start with lde, it will allow shell access using IL:ShellCommand and CHAT(SHELL). Otherwise you'll get an error: Failed to find UNIXCOMM file handles; no processes during startup, and more if you invoke unix communication

reading UnixPipeIn: Bad file descriptor Fork failed. d = 80, 47, 100, 4, 0, 0

The other differences are currently hypothetical (networking startup using 'ldeether' instead of 'lde'; color support didn't use X but rather a Sun specific device).

Can I make the vmem bigger than 256MB?

256 (MB) is as big as the VM can be.

D-machines and Medley 2.0 had 24 bit pointers and 8 bit CDR-codes. (pointer granularity Is 4 bytes so address space was 2^26 or 64 MB)

assuming the "new" CDR-coding with 28 bit pointers and 4 bit CDR-codes is still effective; 2^30 or 256 MB. Going beyond 2^30 would mean turning off CDR-coding which would eat into the gain.
