; 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)

; (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)
