I've got 16M of non-EDO RAM and my machine runs 2.0.13 nicely.
When I use 16M of EDO RAM, it also runs nicely.
When I use 16M of each, it freaks. X doesn't work. (3.1.2C)
Everything else works, but no X. Odd.
Thoughts? The motherboard appears to be able to handle it -- the BIOS
has a little note -- 'bank0 EDO: no' 'bank1 EDO: yes'.
