The Locate DiskBuffer directive is required for all programs that boot from hard disk or diskette. The name of this entity is ignored by RTLoc, but must be present. The disk buffer is required by the disk loader to read the application from disk. It must reside in memory addressable in real mode, must have a size of at least 8k and needs a minimum alignment of one disk sector (512 bytes).

Example:

Locate  DiskBuffer  "Disk IO Buffer"  DOSMem

The disk buffer is a discardable entity with a default size of 64k. If booted from floppy disk, a disk buffer which does not span a 64k boundary may result in improved boot time.
