# hfs-boot
GS/OS Boot block + loader for HFS
Limitations:
* Boot volume must use 512 byte allocation blocks (ie, max size is 32MB. This limit should be removed at some point)
* All file data / catalog data needs to be in the first 3 extents (no overflow extent checking)
* The HFS FST caches the volume block count before GS/OS knows what it is. This causes display issues in
Finder, etc. This could be fixed by the FST using the volume size information from the Master Directory Block or GS/OS
querying the device block count sooner.
