[edit] FreeMiNT's buffer cache

FreeMiNT 1.15 has a new global block cache. It's currently used from the NEWFATFS, ext2fs and MinixFS 0.70.

The cache can be increased at boot time with the configuration keyword "CACHE=<size in kb>" in MiNT configuration file.

For example: "CACHE=500" sets the cache to a size of 500 kb (if enough memory is available). Default cache size is 100 kb. It's recommended to increase the cache if you use many MinixFS 0.70 and NEWFATFS partitions. Currently, the cache is first allocated from TT-RAM and then from ST-RAM.

Note for removable medias: the cache try to automatically lock the drive if there are unwritten sectors in cache.
