free RAM

[Brian]

Have you played around with drive buffers? You could remove addbuffers for the floppy and lower the buffers for the harddrive partitions (as every harddrive partition has it's own buffer you could also limit the amount of partitions on the machine or at least disable unused partitions when playing games). AVAIL FLUSH might also give a bit of extra memory.

A clean 3.1 setup in WinUAE have 190K in use with just a single floppy and a single HDD with minimal buffers (3) to each when started with no startup-seq after running avail flush, run add21k and it's 170K.
