; load_high:	loads (the remainder of) a file into high memory.

;		Assumes CS == DS.
;
; Inputs:	SI  = file handle/cluster pointer
;		EDI = target address in high memory
;		EAX = maximum number of bytes to load
;		DX  = zero-padding mask (e.g. 0003h for pad to dword)
;		BX  = subroutine to call at the top of each loop
;                     (to print status and check for abort)
;		[MyHighMemSize] = maximum load address
;
; Outputs:	SI  = file handle/cluster pointer
;		EBX = first untouched address (not including padding)
;		EDI = first untouched address (including padding)
;		CF  = reached EOF
