INT 15 - EISA(Enhanced Industry-Standard Architecture) A 32-bit superset of the IBMInternational Busiuness Machines ATIBM PC AT's expansion bus (which is now known as the ISA or Industry-Standard Architecture bus). SYSTEM ROM(Read-Only Memory) A memory for program storage which may not be changed by the program as it runs. - READ SLOT CONFIGURATION INFORMATION
	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(Enhanced Industry-Standard Architecture) A 32-bit superset of the IBMInternational Busiuness Machines ATIBM PC AT's expansion bus (which is now known as the ISA or Industry-Standard Architecture bus). 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
