## AI overview

ReactOS Newsletter 66 covers work on a replacement FAT filesystem driver using the FullFAT library, including its prototype and ongoing implementation. It also describes ARM team improvements to the kernel memory pool and welcomes a new developer.

## Source excerpt

FAT A short while ago the FullFAT library was mentioned on the ReactOS forum and then brought to the attention of the developers by IRC regulars. Written by James Walmsley, it is a platform independent library for accessing FAT12/16/32 partitions and it was suggested that a new IFS driver could be written using it. The current FAT driver was written against an older, less NT compliant kernel and was never extensively tested on Windows to begin with.
