AX = D801h CH = function number to read CL = slot number (including embedded and virtual) DS:SI -> 320-byte buffer for standard configuration data block
Return:
CF clear if successful AH = 00h DS:SI buffer filled CF set on error AH = error code (80h-83h,86h,87h) (see #00539) BX destroyed
Note: Call with AL=81h if using 32-bit CS addressing mode instead of 16-bit. This function is also supported by the Compaq SystemPro 486, but it uses more than 1297 bytes of stack.
BUG: Some implementations appear to destroy the DF direction flag; the Novell DOS 7+ memory managers explicitly clear it afterwards.
