INT 1A - PCMCIA Socket Services - INQUIRE ADAPTER
        AH = 84h
        AL = adapter number
Return: CF clear if successful
            AH destroyed
            BH = number of windows
            BL = number of sockets (1-16)
            CX = number of EDCs
            DH = capabilities (see below)
            DL = status change interrupt used (only if DH bit 3 set)(see below)
        CF set on error
            AH = error code (01h) (see AH=80h"PCMCIA")
SeeAlso: AH=80h"PCMCIA",AH=85h"PCMCIA",AH=87h

Bitfields for capabilities:
 bit 0  indicators are per-adapter rather than per-socket
 bit 1  power management is per-adapter rather than per-socket
 bit 2  data bus width is per-socket rather than per-window
 bit 3  status change interrupt
 bit 4  status change interrupt is software shareable
 bit 5  status change interrupt is hardware shareable
 bits 6-7 reserved (0)

Values for status change interrupt usage:
 00h-0Fh IRQ level
 10h    NMI
 11h    I/O check
 12h    bus error
 13h    vendor specific
 14h-FFh reserved
