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 #00539) AL = bit flags (see #00538) 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 #00540) 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
Bitfields for EISA AL bit flags: Bit(s) Description (Table 00538) 7 set if duplicate IDs 6 set if product ID readable 4,5 slot type (00=expansion, 01=embedded, 10=virtual device) 0-3 duplicate ID number if bit 7 set
