MaxTransfer is required for the FFS. Since FFS will request the largest possible number of blocks it can (contiguous sectors in a data file to be read or contiguous free sectors for a write), the driver/controller needs to be able to handle that size of request. Most controllers are limited in the number of sectors that can be transferred at once, and if the driver does not allow for multiple operations to cover the requested data size, you will end up with errors. MaxTransfer simply limits the amount the FFS will request in one chunk. -larry -- "Intelligent CPU?
