WB installation fo both 1.3 and 2.04 ?

[Thomas]

2.0 FastFileSystem works perfectly on 1.3. Even 3.1 file system works on 1.3.

You need to install FastFileSystem into the RDB because 1.3 does not contain it in ROM.

And you need to check Kickstart version in the beginning of Startup-Sequence and then load either WB 2.0 or 1.3 depending on Kickstart version.

Why? You cannot boot WB 2.0 on Kick 1.3 and WB 1.3 does not work very well on Kick 2.0, either. Better boot the respective WB automatically depending on the active Kickstart version.
