+; 32-bit bcopy routine for real mode
+;
+; We enter protected mode, set up a flat 32-bit environment, run rep movsd
+; and then exit. IMPORTANT: This code assumes cs == 0.
+;
+; This code is probably excessively anal-retentive in its handling of
+; segments, but this stuff is painful enough as it is without having to rely
+; on everything happening "as it ought to."
+;

+; bcopy:
+; 32-bit copy, overlap safe
+;
+; Inputs:
+; ESI - source pointer (-1 means do bzero rather than bcopy)
+; EDI - target pointer
+; ECX - byte count
+;
+; Outputs:
+; ESI - first byte after source (garbage if ESI == -1 on entry)
+; EDI - first byte after target
+;
+bcopy: jecxz .ret
+ pm_call pm_bcopy
+ add edi,ecx
+ add esi,ecx
+.ret: ret
+
+;
+; shuffle_and_boot_raw:
+; The new version of shuffle and boot.
+; Inputs:
+; ESI -> Pointer to list of (dst, src, len) pairs(*)
+; EDI -> Pointer to safe area for list + shuffler
+; (must not overlap this code nor the RM stack)
+; ECX -> Byte count of list area (for initial copy)
+;
+; If src == -1: then the memory pointed to by (dst, len) is bzeroed;
+; this is handled inside the bcopy routine.
+;
+; If len == 0: this marks the end of the list; dst indicates
+; the entry point and src the mode (0 = pm, 1 = rm)
