INT 31H 000fH: Set Multiple Descriptors

                                                    Compatibility: DPMI 1.0+ 
 Expects: AX    000fH
          CX    number of descriptors to set
          ES:DI (or ES:EDI) sel:off of buffer containing a series of 2-byte
                selectors and 8-byte LDT entries
          ──────────────────────────────────────────────────────────────────
 Returns: CF    NC (clear) if successful;
                else AX = DPMI Error Code
                     CX = number of entries copied
          ──────────────────────────────────────────────────────────────────
    Info: This fills one or more LDT entries with data you supply.

          The buffer must be formatted as:

            Offset Size Contents
            ▀▀▀▀▀▀ ▀▀▀▀ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀
             +0      2  wSel1       valid selector to define
             +2      8  rDesc1      descriptor for that selector
            +0aH     2  wSel2       valid selector to define
            +0cH     8  rDesc2      descriptor for that selector
              .
              :

    Note: If the call fails due to an invalid selector, the host will
          return CX as the number of valid selectors that it found before
          encountering the bad apple.
