Int 15 Fn D800  - Eisa System Rom - Read Slot Configuration Information    [X]

   AX = D800h
   CL = slot number (including embedded and virtual)

Return: CF clear if successful
       AH = 00h
   CF set on error
       AH = error code (80h,82h,83h,86h,87h)(see #0463)
   AL = bit flags (see #0462)
   BH = major revision level of configuration utility
   BL = minor revision level of configuration utility
   CX = checksum of configuration file
   DH = number of device functions
   DL = combined function information byte (see #0464)
   SI:DI = 4-byte compressed ID (DI = bytes 0&1, SI = bytes 2&3)

Note:  call with AL=80h if using 32-bit CS addressing mode instead of 16-bit

Bit(s) Description (Table 0462)
 7 set if duplicate IDs
 6 set if product ID readable
 4,5   slot type (00=expansion, 01=embedded, 10=virtual device)
